SYSTEM DESIGN PROPOSAL FOR INTRUDER AND HOLD-UP ALARM SYSTEM INCORPORATING REMOTE SIGNALLING
The following system design proposal is for an Intruder and Hold-up Alarm System, incorporating Remote Signalling, this will be installed in compliance with PD 6662:2010 (PD 6662:2010 is the UK implementation of BS EN 50131-1:2006+A1:2009) and BS 8243:2010.
In accordance with the DD CLC/TS 50131-7:2010, a site survey and risk assessment of your property has been carried out. The risk assessment relates solely to the grading and design of the proposed intruder alarm and is based upon information and any valuations available at the time of survey, a copy of the risk assessment is attached for your information. As a result the system has been specified and designed as security grade 2, notification option C.
You should consult with your insurer in relation to any new I&HAS, or modification of an existing I&HAS, conforming to this British Standard.
Design objectives for intruder alarm
All equipment will be environmental class 2 unless otherwise stated.
The system is capable of generating confirmed alarms for the purposes of obtaining Police response, note that no confirmation will be provided from any activity in the entrance foyer. (See notes on confirmation).
The supervised premises consist of a small, brick built, commercial unit used as a design centre.
Note: Locations (Front, Rear, Left and Right) are given as an observer standing outside, and facing the front of the premises. (See attached schematic).
Circuit 1 Final exit/entry.

A surface mounted magnetic door contact to be fitted on the rear door. This is designed to initiate an entry timer of 10 secs to allow the system to be unset using a digital key.
Circuit 2 Alarm.

A passive infra-red detector, incorporating anti-mask technology, capable of providing an area of unobstructed cover of 12m by 90 degrees, is to be retained in the rear right corner of the workshop, to provide general trap protection to the area.
Circuit 3 Alarm.

A passive infra-red/microwave detector, incorporating anti-mask technology, capable of providing an area of unobstructed cover of 12m by 90 degrees, is to be retained in the front right corner of the workshop, to provide general trap protection to the area.
Circuit 4 Alarm.

A heavy duty magnetic contact (Environmental class 3) is to be fitted to the roller shutter in the workshop area
Circuit 5 Alarm.

An inertia detector, with a detection radius of 2.5m, is to be fitted to the window in the finishing workshop.
Circuit 5 24 hour.

A Hold-up device to be sited at the trade counter left hand side.
Circuit 5 24 hour.

A Hold-up device to be sited at the trade counter right hand side.
Note for Installer: You may not require confirmation of HUD for new systems. Check the requirements of your ACPO(S) policy.
Control equipment

The system will be controlled by a XXX Control Panel, fitted on the rear wall of the design shop.

The control panel will be fitted with a standby battery which will power the system for up 12 hours in the event of a mains power failure.

Operation of the system will be by a Digital key/Keypad, located adjacent to the rear door.

A (13 amp) un-switched fused spur should be provided and installed on the rear wall of the design shop adjacent to the position marked for the control unit. This will provide mains power for the system and should be installed by a qualified electrician.
Unsetting

The system will be unset by means of a Digital Key (prox tag) once the entry door has been opened (BS 8243:6.4.5). See attached notes.
Notification

The system will notify alarm conditions to XXXXXXX Ltd, Alarm Receiving Centre, via the redcare/GSM located adjacent to the control equipment. See attached notes.

The ARC will contact the keyholders when the following signals are received:- Unconfirmed and confirmed alarm, tamper and fault condition, mains fail, ATS fail and detector inhibited on system reinstatement.

A self-powered audible warning device, XXXXXXX (environmental class 4), is to be retained and rewired internally, high up on the rear wall. This unit is designed to cut-out after 15 minutes.
Installation notes

An unswitched fused spurs are already provided, by the customer, adjacent to the Control/Signalling equipment.
Certification

Upon completion of the installation a Certificate of compliance will be issued.
Intervention

The system is designed to expect police response in the event of a confirmed alarm condition, otherwise response will be keyholder only.
Maintenance

Preventative maintenance and corrective maintenance will be provided in accordance with the requirements of DD 263:2010 and the terms and conditions of our maintenance contract. Preventative maintenance will consist of 1 site visit and 1 remote system check to be carried out alternately on a 6 monthly basis.

Should you require any help or assistance during normal office hours, please contact us on XXXX. For emergency repairs out of hours please call XXXX.
SPECIFICATION NOTES FOR THE INSTALLATION OF AN INTRUDER ALARM SYSTEM
DESIGNED TO GENERATE A SEQUENTIALLY CONFIRMED ALARM.
INSTALLED IN COMPLIANCE WITH PD 6662:2010 and BS 8243:2010.
ALARM CONFIRMATION
“IAS incorporating alarm confirmation technology”
In order to be eligible for a URN for police response, the current ACPO policy requires all new alarm installations to be capable of providing confirmation of the alarm condition
A sequentially confirmed alarm is one which results from the activation of two or more independent detectors or Hold-up devices. These must be configured so that an activation means there is a high probability that a genuine intrusion or attempted intrusion or a personal attack has occurred. The second activation must occur within a fixed period of the first event, known as confirmation time.
Confirmation time for the Intruder Alarm system will be 30 minutes.
Confirmation time for the Hold-up Alarm system will be 15 hours.
Activation of a single Intruder detector will generate an unconfirmed alarm and at this stage only the Key Holders will be informed.
Activation of a second Intruder detector within the confirmation time, will generate a confirmed alarm and both the Police and Key Holders will be informed.
If a second activation does not occur within confirmation time, the system will reinstate itself.
If a detector is in alarm at the time of reinstatement, it will be inhibited to prevent a further alarm being generated. A signal will be sent to the Alarm Receiving Centre to indicate that detector inhibition has occurred, and the keyholder will be informed. The action to be taken on receipt of this signal may need to be discussed with the user’s Insurance Company as it may not be acceptable to them for a detector to be left inhibited.
Should a further activation occur after reinstatement, this will generate a further unconfirmed alarm, requiring a further independent activation within the confirmation time to generate a confirmed alarm.
UNSETTING THE ALARM
The system will be unset by means of a Digital key (swipe card, proximity device, etc) once the entry door has been opened (BS 8243:6.4.5)
Opening the entry door starts the entry timer and inhibits confirmation the system is unset by means of the portable device. Once the entry timer expires the means of confirmation are restored.

Notes:-

a)     If the digital key fails, it will be possible to complete the unsetting by means of a user code, but only after the entry time has expired. This action should only be used as an exception and evidence of repeated use may affect both police response and your insurance.
b)     Care should be exercised when using this method of unsetting as it is possible to generate confirmed alarms from devices not on the entry route once the entry timer has expired.
NOTIFICATION
The redcare/GSM will transmit alarm information to an Alarm Receiving Centre and have the use of two independent signalling paths a BT landline and a Cellular Telephony channel.
Failure of a single path is reported to the Alarm Receiving Centre as an ATS path fail, with the second path still being available to transmit alarm information.
Failure of both paths, within 96 hours, will result in the Alarm Receiving Centre contacting the emergency services.

Notes:-

1.     Redcare will only operate over a BT line so you should advise your alarm provider/maintainer if you wish to change your telecom service provider.
2.     It is also recommended that the line used for redcare is not used with fax machines, other modems, credit card terminals, or other similar data transmission devices as these may interfere with the redcare signals, without the provision of additional equipment, available through your alarm provider/maintainer.
