---

A maximum time period should be permitted to complete the unsetting procedure. When the maximum unsetting period is exceeded an alarm condition should be notified.

NOTE EN 50131-1:2006, 8.3.8.2, specifies a maximum period of 45 s shall be permitted to complete the unsetting procedure.

When setting or unsetting of l&HAS is to be carried out in two stages, the route between these two points should be carefully considered and be as short as possible.

EXAMPLE Setting started at the CIE or ACE and completed at the entry/exit point.

Indication provided during the setting and unsetting procedures, when setting or unsetting is achieved in two stages, should be perceivable throughout the entry/exit route and immediately outside the entry/exit point.

The CIE should be configured such that signals or messages from detectors on the exit/entry route, activated during the setting or unsetting procedure, are not processed as intruder signals or messages. Detectors located on the exit/entry route should be monitored and l&HAS should not set until l&HAS is in the normal condition.

When a detector that is not on the exit route is activated during the setting procedure an indication should be provided and completion of the setting procedure prevented.

When a detector that is not on the entry route is activated during the unsetting procedure an alarm condition should be notified.

Mandatory requirements for indications are included in EN 50131-1:2006. These require all mandatory indications to be available together at one location. Indications may be repeated, in whole or in part, at other locations.

Individual indication should be provided to indicate the alarm status of each detector including processing capability, e.g. movement, vibration, acoustic or infra-red beam detectors.

Not more than ten detectors not including a processing capability may share a common means of indication, e.g. magnetic or mechanical contacts.

Individual detectors may be identified individually or grouped together for control or other purposes.

EXAMPLE To provide part setting/unsetting facilities, isolation of several detectors using a single command or operation, or to simplify the identification of the origin of an alarm condition.

Minimum requirements for notification are included in EN 50131-1:2006. Depending on the grade of l&HAS notification may be by WD or ATS or a combination of both.

When notification is by two WD consideration should be given to installing the two WD at positions remote from each other.

Consideration should be given to enabling the sound of l&HAS WD to be differentiated from the sounds of WD’s of other alarm systems.

When a WD is used to supplement an ATS, operation of the WD may be delayed for a period not exceeding ten minutes or suppressed completely, providing the ARC has confirmed receipt of the alarm signal from the ATS.

NOTE National regulations may require a delay in the operation of the WD. The duration the WD is permitted to operate may be similarly subject to National regulation.

Many communication formats exist for the transmission of messages between SPT and an ARC. Care should be taken to ensure the ARC can accept signals from the SPT to be installed and process all signals correctly.

Care should be taken to ensure power supplies used in l&HAS are adequate for the load under both normal and alarm conditions including when the APS is being recharged.

When power is normally derived from a mains supply with an alternative power source (APS) as backup, care should be taken to ensure the capacity of the alternative power source is capable of powering the l&HAS, for the required standby period as specified in EN 50131-1:2006.

The electrical load of l&HAS should be measured with the system in the normal, i.e. non-alarm, condition and the information recorded in the as fitted document.

The maximum electrical load should also be measured when l&HAS is in an alarm condition, i.e. when WD(s) are operating and SPT(s) transmitting and the information recorded in the as fitted document.

The APS should be capable of powering l&HAS for the period specified in EN 50131-1:2006, 9.2, Table 23 in both normal and alarm condition.

Where the APS is a battery, allowance should be made for loss of capacity during the lifetime of the battery and when the current drawn exceeds the manufacturer’s “20-hour” discharge rate.

The planned response (intervention) following the activation of l&HAS should be clearly agreed and documented between the parties.

8. Installation planning

   1. General

Prior to commencing the installation of system components the following issues should be considered.

All system components should be installed in accordance with the manufacturer’s recommendations. If installation of a component in accordance with the manufacturer’s recommendations is not possible advice should be sought from the manufacturer or supplier.

System components should be suitable for the environmental conditions in which they are to operate.

To ensure the performance of l&HAS is consistent with the requirements as detailed in the system design proposal a technical survey of the premises to be supervised should be carried out.

The objective of the technical survey is to ensure, as far as is possible, that l&HAS provides the performance specified in the system design proposal. Examples of issues, which should be considered during a technical survey, are included in Annex H.

NOTE Depending on the size and complexity of the planned l&HAS the technical survey may be carried out at the same time as the location survey or may be carried out by the installer prior to commencing installation of l&HAS or may be carried out independently.

The technical survey should consider the operation of the system, particularly setting and unsetting procedures, to ensure operation of l&HAS is as simple as possible.

The technical survey should verify the selection of components specified in the system design proposal and should also confirm the proposed siting of the components is consistent with the optimum performance and manufacturers recommendations.

The siting of components to be operated by a user should be checked to ensure ease of operation.

Interconnection requirements should be considered and the means specified in the system design proposal verified.

The pre-installation survey may identify issues which may require the modification of the system design proposal. Any such changes should be agreed with the client and be recorded.

Subject to the size and complexity of the planned l&HAS consideration should be given to preparing an installation plan. The installation plan should be based on the system design proposal and consider any issues identified in the technical survey.

The installation plan should specify where each system component is to be located and how it should be sited.

1. Height from floor level.

Details of the interconnections required and, if wired, cable types and routing should also be specified.

The system configuration should be finalised and agreed.

2. Setting/unsetting procedures, circuit programming, WD delay (if any) and duration periods.

The installation plan should include an equipment schedule detailing all equipment to be installed including cable (if any).

9. System installation

   1. Installation process

The system should be installed and configured in accordance with the system design proposal. Any deviations from the system design proposal should be agreed, in writing, with the client.

9. Inspection, functional testing and commissioning

   1. Inspection

An inspection of the system should be carried out on completion of the installation of l&HAS to confirm l&HAS has been installed in accordance with the system design proposal and the installation plan (if prepared). Any deviations from the system design proposal should be recorded for inclusion in the as-fitted document.

The performance of each detector should be tested and compared with the requirements included in the system design proposal and the installation plan (if prepared). Particular care should be taken with movement and vibration detectors which may require adjustment of range or coverage. Other types of detectors may also require final adjustment prior to commissioning.

The configuration of site-specific data should be checked to confirm the indication and notification provided is as required in the installation plan.

Finally a complete operational test should be carried out, including activation of any WD and SPT. Where SPT is installed a check should be made with the ARC or other receiving centre to ensure these signals were successfully received.

On completion of the tests l&HAS should be placed into operational mode.

Handover of l&HAS to the user should be carried out by a person with the appropriate training and experience.

A full demonstration of l&HAS should be provided including the operation of detectors, the use of hold-up devices and how these should be tested.

An explanation of the functions of the CIE, ACE and ATS should also be provided. Communication procedures with the ARC (if any) should be explained.

Clear and concise operating instructions should be provided, these should include both how the CIE is operated and the specific setting and unsetting procedures for the l&HAS. These instructions should be provided to all users responsible for operating the l&HAS.

Depending upon the complexity of l&HAS users should be offered training in the operation of the l&HAS. The level of training given should be commensurate with the complexity of the l&HAS.

The training should emphasize how unwanted alarms can be avoided, e.g. the proper closing of doors, windows and the switching off of equipment which might adversely influence detectors.

Following the handing over of l&HAS it is recommended that l&HAS is tested for a period to be agreed with the client. During this period l&HAS should be operated normally.

To minimise the risk of unwanted alarms being generated during the test period the means of notification should be inhibited.

Alternatively when an ATS has been installed, only the operation of any WD may be inhibited, the ATS remaining operational. The ARC should be instructed to inform only the installation company, alarm company or client in the event of an alarm condition being generated.

Any alarm conditions occurring during the test period should be investigated by the installation company, alarm company or client and corrective action taken. Following completion of the agreed period without unwanted activations l&HAS should be fully commissioned.

Following the successful completion of the test period, where applicable the ARC should be informed that l&HAS is fully operational. The responding authority, if any, should also be informed and where necessary provided with any keys or access codes.

The client should be requested to sign an acceptance certificate stating l&HAS has been installed in accordance with the as-fitted document and operates accordingly and that sufficient instruction and training has been provided to ensure the proper operation of the l&HAS.

Documentation should be prepared, based upon the system design proposal, amended to reflect any changes to l&HAS design found to be necessary during the installation process. The as-fitted document should be an accurate record of the installed l&HAS including all information relating to the equipment installed and its location. If warranted by the size and complexity of l&HAS the as-fitted document should also include details of the types of cables used and their routing.

The as-fitted document should be made available to maintenance and service personnel.

The installation company should provide the client with a certificate of conformance stating l&HAS has been installed in compliance with the as-fitted document.

When the l&HAS, or any components of the l&HAS, are claimed to comply with any legislation, regulation(s), National or European Specifications, any such claims should be included in the certificate of conformance.

9. Documentation and records

   1. Documentation

The following documentation should be provided to the client. The client or user should be requested to make this documentation available should l&HAS require modification, repair or maintenance and should also ensure the documentation is kept up to date. Where applicable the documentation should be prepared in accordance with EN 61082-1:

1. as-fitted document;

2. system operating instructions;

3. operating instructions should be provided in sufficient detail to minimise the possibility of misoperation. Consideration should be given to dividing the instructions into two sections:

• actions required to set and unset the system and carry out a limited range of control functions e.g. setting, unsetting, resetting, isolating, inhibiting or testing;

• detailed instruction covering all the other functions of the l&HAS;

4. installation company:

the name, address and telephone number of the individual or installation company;

5. maintenance and repair:

the name, address and telephone number of the company or individual responsible for maintaining and/or repairing the l&HAS, including details of how these organisations or individuals may be contacted at all times;

6. monitoring:

vii) verification:

details of any procedures relating to the verification of alarm conditions;

viii) intervention:

the name, address and telephone number of the organisation responsible for attending the supervised premises following the generation of an alarm condition;

9. acceptance certificate;

10. certificate of conformance.

11.2 Records

A system record should be provided to record any information necessary to ensure l&HAS operates as intended. The record should include details of the time and date of any alarm conditions, which detector was responsible for generating the alarm condition and in the case of an unwanted alarm condition, details of any remedial action initiated to prevent the occurrence of further unwanted alarm conditions. The record should also include details of any modifications or additions to the l&HAS.

The system records may be recorded in any medium or at a location remote from the supervised premises providing it is easily accessible to persons maintaining the l&HAS. An example of the items to be recorded and the format of a system record (log book), which could be located at the supervised premises, are shown in Annex I.

The records should be supplied in a manner suitable for the long term preservation of the records. When the records are stored at the supervised premises the client should be requested to make the records accessible to those responsible for maintaining l&HAS and also to ensure the records are securely stored when not in use. The client should also be made aware of the need to ensure the records are kept up to date

12. .Operation of l&HAS

The client and/or user of l&HAS and those responsible for the maintenance and service of l&HAS should be made aware of their responsibility to

1. ensure that only individuals trained to operate the system are allowed to operate it and that l&HAS is operated in accordance with operational instructions and training,

2. ensure the premises are used and maintained in a manner such as not to cause unwanted alarms,

3. report any defects in l&HAS promptly to the responsible alarm company,

4. report any changes to the construction or to the use of the premises which might adversely influence the performance of the l&HAS,

5. maintain the relevant documents and records.

12. Maintenance and repair of l&HAS

    1. General

It is the client’s responsibility to arrange for l&HAS to be properly maintained (inspected and serviced) and repaired as necessary. An arrangement should be made between the client and a competent organisation for the maintenance and repair of the l&HAS. The arrangement should specify the method of liaison necessary to provide access to the supervised premises. The name and telephone number of the maintenance and repair organisation and the alarm company should be prominently displayed at the location of the CIE or ACE. Examples of issues, which should be considered when maintaining IAS, are included in Annex J.

To ensure the continued correct functioning of the IAS, l&HAS should be periodically maintained (inspected and serviced). A maintenance schedule should be agreed immediately upon the completion of the installation.

The user of l&HAS should be informed of those parts of the system that will be inoperable during maintenance.

Any batteries should be replaced at intervals not exceeding the battery and equipment manufacturers recommendations. Care should be taken that all equipment is properly reinstated after testing.

All intervention during maintenance or repair, including testing, should be recorded in the system record, e.g. log book.

It is important to ensure when maintaining an l&HAS that maintenance operations do not result in the generation of an unwanted alarm. Special care should be taken when testing hold-up devices because of the high risk of false alarms.

If a link to an ARC or other remote manned centre is to be used during the test, then it is essential to notify the ARC or other remote centre before undertaking the test.When the transmission of signals to an ARC or other remote manned centre is prevented during testing, a visual indication of this state should be given, either automatically or manually, at the control and indicating equipment.

The occupants of the premises should be notified of any test of l&HAS which may result in the operation of the WD.

In the event of any indication of a malfunction or damage to any part of l&HAS the user should immediately inform the organisation or individual responsible for the maintenance and repair of l&HAS so that any necessary remedial action may be taken. The time within which repair of l&HAS will commence, following a request to the organisation or individual responsible for carrying out the repairs, should be agreed.Annex A
