Description
49VO-WRFO SIMPLEX, VO, WALL RED FIRE WP.
49VO-WRFO Simplex, TrueAlert ES weatherproof addressable appliances provide visible and audible/visible notification for indoor and outdoor, extended temperature and extended humidity applications. They are individually addressed and receive power, supervision, and control signals from a Simplex fire alarm control unit providing IDNAC Signaling Line Circuits (SLCs).
TrueAlert ES Operation
Separate visible and audible notification TrueAlert ES addressable appliances on IDNAC SLCs provide separate visible and audible notification using a single two-wire circuit that also confirms connection to the individual notification appliance’s electronic circuit. This operation increases circuit supervision integrity by providing supervision that extends beyond the appliance wiring connections.
Reduced current allows efficient IDNAC SLC operation
With IDNAC SLCs, a constant 29 VDC source voltage is maintained, evenduring battery standby, allowing strobes to operate at 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.
Reduced Installation and Testing Time.
With separate controls on the same two-wire SLC, installation time and expense for both retrofit and new construction can be significantly reduced. When Class B wiring is used, wiring can be “T” tapped, allowing more savings in distance, wire, conduit (size and utilization), and overall installation efficiency. Use of Self-Test and Magnet Test features improves installation efficiency. TrueAlert device reports conveniently identify information about each connected appliance.
