About Knight Fire & Security
Knight Fire & Security is a UK manufacturer of detection and alarm accessories, and this page lists the Knight products JEM Systems UK carries. The range centres on intruder alarm hardware: surface and flush magnetic door contacts in Grade 2 and Grade 3 versions, angled contacts for roller shutters and rebated doors, armoured-cable contacts for exposed positions, and seismic shock and tilt sensors.
You will also find panic buttons, including confirmable and double-end push versions, resettable call points and exit switches, internal sounders, resistor packs and mounting spacers.
When choosing a contact, check the following:
- the grade required by the system specification
- the operating gap and fixing style (surface, flush or angled)
- the resistor configuration your control panel expects, as many Knight contacts have selectable multi-resistor settings
- the cable length and whether armoured sleeving is needed
- the finish and any waterproof rating for outdoor doors
Each product page lists the full specification so you can match it to your panel. To build a complete installation, see our door contacts and sensors and intruder detection collections, or the wider sounders and beacons range.
