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.
An isolator base for System Sensor 200 analogue addressable detectors that stops a short circuit from disabling the whole loop and restores the loop automatically once the fault is fixed.
A plug-in base for System Sensor smoke and heat detector heads in 2-wire systems, with screw terminals for power and remote annunciator connections.
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.
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.
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.
