Addressable smoke & heat detector with short-circuit isolator The BSR-6157/MAR is an analogue addressable smoke detector which integrates functions of optical smoke and heat detection and it can work with any fire detection panel that supports Olympia A Protocol.

It can be adjusted to detect multiple levels of smoke and heat offering flexibility and rich functionality. Also, it integrates a short isolation circuit which is automatically activated and disconnects the defective node from the remaining loop, allowing it to be located by the panel.
