Simplex 4906-9202 ceiling strobes multi candela provides convenient installation to standard electrical boxes. Also, the strobe is individually addressed and individually controlled with power, supervision, and control supplied from a Simplex fire alarm control panel providing IDNAC Signaling Line Circuits (SLCs).

Simplex 4906-9202 provides separately visible notifications using a single two-wire circuit that also confirms connection to the individual notification appliance’s electronic circuit. Besides, this operation increases circuit supervision integrity by providing supervision that extends beyond the appliance wiring connections.

In fact, reduced current allows efficient IDNAC SLC operation. With IDNAC SLCs, a constant 29 VDC source voltage is maintained, even during battery standby, allowing strobes to operate at a higher voltage with lower current and ensuring a consistent current draw and voltage drop margin under both primary power and secondary battery standby. Efficiencies include wiring distances up to 2 to 3 times farther than with conventional notification; or support for more appliances per IDNAC SLC, or use of smaller gauge wiring, or combinations of these benefits, all providing installation and maintenance savings with high assurance that appliances that operate during normal system testing will operate during worst-case alarm conditions.
