Alarm System Accessories

Alarm system accessories are the parts that let an intruder alarm be armed, extended, kept in repair and tested. This range covers keyfobs and proximity tags, wireless receivers, repeaters and zone expanders, plug-on communicators and speech diallers, replacement bell-box covers and dummy backplates, detector brackets and housings, backup batteries and power modules, and installer tools such as walk testers and a break-glass tester. Match any part to the panel or detector it has to work with.

Choosing Alarm System Accessories

Start from the system on the wall: a cover, receiver or keyfob is usually made for one maker’s panel or sounder.

Keyfobs and tags

Keyfobs arm and disarm from a pocket. The Pyronix KEYFOB-WE is a two-way four-button keyfob graded EN50131 Grade 2, and the Ajax SpaceControl S 110753.04.WH1 has arm, disarm, night and panic buttons on 868 MHz Jeweller radio. Proximity tags are presented to a reader or keypad instead, such as the Ajax Tag 38228.90.BL, a pack of 3 MIFARE DESFire fobs.

Receivers, expanders and communicators

The Pyronix UR2-WE brings two-way wireless devices onto a wired panel, taking up to 20 devices and switching 2 alarm relays. The Pyronix EURO-ZEM8+ adds 8 wired zones on RS-485, and the GJD392 D-TECT X receiver has 4 channels, expandable to 16. Communicators send the alarm off site: the Pyronix DIGI-GPRS adds a GPRS path to Enforcer and PCX panels with a SIM that is not supplied, and the Texecom CGA-0001 speech dialler calls up to 8 standard or mobile numbers over a PSTN line.

Bell-box covers and dummy boxes

Replacement lids keep a sounder weatherproof and tidy: Pyronix FPDELTA lids for Deltabell bases come in colours such as white, red, blue, yellow and chrome, and the Texecom WDA-0005 is an Odyssey X1 cover with a black frame and red lens. Dummy backplates such as the Texecom FCE-0033 contain no electronics and act as a decoy.

Installing and testing

For commissioning, the Pyronix FP05130 reproduces the flex and shatter signals of breaking glass, so glass-break detectors can be tested without breaking a window. The Optex BAU-4 aligns SL Series beams automatically, so one technician can set up a 200 m beam. Ajax, Pyronix and Texecom make most of the accessories on this page.

Frequently asked questions

What accessories does an alarm system need?

Accessories extend or maintain an alarm rather than replacing the panel. Common examples include keyfobs and tags for arming, receivers and zone expanders for adding devices, communicators for remote signalling, standby batteries, and mounting brackets or replacement covers. Check that an accessory is made for your panel's brand and radio type. The range here includes keyfobs, expanders, brackets, enclosures and batteries.

Can you replace individual parts of an alarm system?

Yes, many alarm parts can be swapped on their own, such as a detector's mounting bracket, a sounder cover, a hub's backup battery or an internal power board. Match the replacement to the exact device family, because brackets and housings are usually made for one model range. The range here includes replacement brackets, housings, sounder covers and internal batteries.

What components make up an alarm system?

An intruder alarm usually combines a control panel, a keypad or keyfob for setting, detectors such as motion sensors and door contacts, and an internal or external sounder. Many systems add a communicator to signal an app or monitoring centre. Accessories such as expanders, repeaters and power modules help the system grow. The range here includes repeaters, expanders and power modules.
