A 4 inch standard European flangeless mounting base for a plain detector position, UL/ULC listed.
A sounder base that takes the same address as its detector but uses its own device type on the loop, and recognises the System Sensor synchronisation protocol.
An intelligent isolator base for detectors, 6.2 inch in diameter, for loops that need short circuit isolation at the detector position.
The plug-in base for Morley Advanced intelligent sensor ranges, in the ivory version. The standard MI-B501AP is white and the BK version is black.
The standard base for System Sensor 500, 200, 200+ and 200 Advanced intelligent sensors, with a tamper-resistant option and a break-off address tag.
A two-wire heated base for System Sensor 200 analogue addressable detectors, used where frost or condensation could otherwise cause false alarms.
A universal detector base that fits all Apollo detectors in the Soteria, Discovery and XP95 ranges. It supports isolated and non-isolated devices and has a wide interior for easy access to cables and terminals.
A white flame-retardant polycarbonate mounting box for flush fitting Soteria Dimension detectors into a ceiling opening. It is held in place by self-aligning fixing tabs.
Mounting base for all Intelli-Sense detectors, 110 mm across and 16 mm deep, with device locking and remote indicator connections.
