As with the criteria for NSI approval, ACPO also has necessary approvals alarm installation companies must meet in order that the public obtain a proper response to any genuine alarm activations.

• All “URN” applications to include full PD6662-EN50131/1 certification.

• The Installation Company to be certified by the National Security Inspectorate

• All Staff to be Fully Police Vetted

• All Alarm Systems to conform to DD243: 2004 False Alarm management

• The Alarm System and Installer to conform to ACPO Force Alarm Policy

• Liable to Random Police Inspection of Installations

• Use a Police Approved Alarm Receiving Centre

Digital Communicator
The remote signalling of your intruder alarm system will be controlled by Digital Communicator, Dual Com (combined Digi & Aerial), RedCARE Signalling Transmission Unit (STU) or RedCARE GSM GID transmitting to a 24 Hour Manned Communication Centre, noted below, via a Digital Communicator utilising a separated ex-directory incoming calls barred telephone line to dial the alarm receiving centre and signal an activation.

NOTE: If a line fault situation occurs, the system is unable to transmit the second signal required to generate a police response and this may not be acceptable to your insurers.

Dualcom
DUALCOM offers dual path signalling on any telephone network, ADSL or ISDN and can share a telephone line, with a back up radio signal over the Vodafone network to ensure transmission of alarm signals in the event of the telephone line being tampered with or proving faulty and indication of a signal fault on the alarm keypad.

NOTE: This service is subject to a signal strength test to verify availability in the area.

Redcare
REDCARE SIGNALLING TRANSMISSION UNIT using an existing standard exchange BT telephone line (provided no form of electronic data transmission exists on the line, i..e fax or modem, except for BT Broadband which is now compatible) to indicate both activations and line faults to the alarm receiving centre via a continuous electronic signal transmitted down the line.

NOTE: If a line fault situation occurs, the system is unable to transmit the second signal required to generate a police response and this may not be acceptable to your insurers.

Redcare GSM
REDCARE GSM offers dual path signaling via any existing standard exchange BT telephone line (provided no form of electronic data transmission exists on the line, i.e. fax or modem, unless a Modem Compatible Device is fitted and the REN value does not exceed 3, except for Broadband lines which are now compatible with RedCARE) to indicate both activations and line faults to the alarm receiving centre via a continuous electronic signal transmitted down the line, combined with BT Cellnet’s GSM radio network to ensure that if ever there is a break in the telephone line, the GSM network will continue to deliver alarm signals.

NOTE: This service is subject to a signal strength test to verify availability in the area.

Radio/Wireless Alarm Systems
With the introduction of PD6662-EN50131/1 all wireless interconnections from the alarm control panel to the radio detection equipment and control devices are now covered under this standard.

In simple terms as long as the alarm system complies with the DD243: 2004 standard and the installer utilises the recognised 868mhz radio band frequency, all radio systems will be deemed as a grade 2 system.

Radio/wireless alarm systems although quicker to install in terms of installation time and less disruption to the premises and décor, they are more expensive in terms of the technology and features they now have built-in. Today’s systems allow for greater use of features by the end-user and their friends and family.

Selecting a Wireless/Radio Burglar Alarm
In order to select the correct wireless/radio system, this is what you should look for:

• Correct Radio Frequency – Should conform to 868.6625 MHz frequency

• Rolling Radio Codes or Differs – At least 1,000,000 Differs.

• Independent Device Codes – Detectors can learn their own code or differ.

• Radio Jamming or Interference – Allow detection of these signals.

• Low Battery & Tamper – Alert of low battery or tamper, with zone identification.

• Signal Strength – Display Signal Strength for recording in system documentation.

• Ability to report these faults including mains failure to the Alarm Receiving Centre.
