Offered here are industry standard alarm/fire/security addressable monitor modules. Type M500CFS by Edwards ESI. This is an addressable module that fits in a double outlet box. It can be used in several different modes. It can activate an SPDT relay pair upon receiving its programmable address 0-159 from a host alarm controller. Only the panel line is required for power in this use. Alternately, an external 24 volt power source must be applied. This power in turn can be passed on to any smoke detectors, PIR devices, or whatever that require system power.

Speaker supervision and switching can also be accommodated. Each module is addressable with two internal selector switches for up to 150 unique channels. The host controller interrogates its modules sequentially for open, short, fault, or normal operation. Wholesale price of these are typically in the $40 range. Units fit a normal double outlet box.
