Burglar & Intruder Alarms

A burglar alarm pairs a control panel with detectors, contacts, keypads and sounders, and a way of signalling when it goes off. This page brings the whole system together: wireless, wired and hybrid panels and kits, indoor and outdoor motion detectors, glass-break and shock sensors, door, window and shutter contacts, keypads, key fobs and panic buttons, internal and external sounders, communicators, standby batteries and the brackets and covers that finish an installation.

Choosing Burglar & Intruder Alarms

Choose how the system connects, then the detection for its rooms and openings, then the warning and signalling.

Wireless, wired or hybrid panels

The Ajax Hub 2 Plus 22925.40.WH1 is a wireless control panel with Ethernet, Wi-Fi and dual-SIM LTE, support for up to 200 devices and photo verification from MotionCam detectors. The Pyronix Enforcer V11 ENF32UK-WE is a hybrid panel with 32 wireless zones onboard, expandable to 64, plus 2 wired zones, and it is rated Security EN Grade 2.

Motion and perimeter detection

Indoors, the Optex FlipX FLX-S-DT pairs PIR with microwave, and the Ajax Superior MotionProtect G3 Fibra 117717.09.WH1 is an EN 50131 Grade 3 wired PIR with anti-masking and a 15 m range. Outside, the GJD D-TECT 50 IP (GJD250) is a PoE detector with a programmable range of up to 50 metres, and the GJD509 laser forms a curtain up to 10 m × 10 m. The Hikvision DS-PDSK-P(B) shock detector guards doors, windows and safes against impact.

Doors, windows and shutters

The Elmdene by Potter 6RSA-100-GN is a Grade 2 roller shutter contact with a 55mm operating gap and 1m of stainless steel conduit. The Aritech DC115 is a sealed overhead door contact with 2 m armoured cable for metal doors, gates and fences.

Sounders and signalling

The Ajax StreetSiren Fibra 44412.07.WH1 adjusts from 85 to 113 dB with an LED frame for visual alerts, and the Elmdene by Potter RAPIER-G3S-NC is a stainless steel Grade 3 sounder with twin strobes. The Pyronix DIGI-LAN module sends alarm signals over an existing broadband line and push notifications to a phone. For standby power, the Power Sonic PS-12170VDS M5 is a 12 V 17Ah sealed AGM battery.

Frequently asked questions

What types of intruder alarm sensor are there?

Intruder alarm sensors include PIR motion detectors, dual-tech detectors that add microwave, door and window contacts, glass-break and shock sensors, and outdoor beams and curtain detectors. Roller shutter contacts and panic buttons cover other risks. Pick motion detection for rooms and contacts for openings, and add perimeter detection outside if early warning is needed. The range here includes wired and wireless sensors for indoor and outdoor use.

How is a burglar alarm installed?

A burglar alarm is installed by fixing the control panel inside the protected area and placing detectors and contacts on likely entry routes. Wired devices are cabled back to the panel, while wireless ones are paired with it. The external sounder goes high on a visible wall. A system that needs police response must be fitted by an accredited installer.

How do burglar alarms work?

A burglar alarm uses detectors and contacts to sense movement or an opening door or window while the system is armed. The control panel then sets off internal and external sounders and can send an alert to a phone, a keyholder or a monitoring centre. Users arm and disarm it with a keypad, keyfob or app, and a standby battery keeps it running in a power cut.

How do you turn off a burglar alarm?

Turn off a burglar alarm by entering a valid user code on the keypad, presenting a tag or keyfob, or disarming it in the app. That stops the sounders and disarms the system. If the alarm keeps sounding or will not reset, contact the installer or maintenance company rather than cutting the power, because standby batteries keep the panel and external sounder going.

What is a burglar alarm?

A burglar alarm is an intruder detection system that warns of a break-in with a loud siren and, often, an alert to a phone or monitoring centre. A system can be wired, wireless or hybrid, depending on how its devices connect to the panel. The range here includes panels, detectors, sounders, communicators and standby batteries.
