Kidde’s Integrity Series life safety and mass notification/emergency communications (ECS/MNS) re-entrant speakers and speaker- strobes are high quality appliances for emergency voice communications, as well as alert and alarm tone signals. Integrity’s rugged plastic housing is made from durable and fire retardant, high impact plastic with a slightly textured surface. Housings are rated for outdoor use and are available in red or white. Integrity’s ingenious mounting plate firmly holds the device in place with a single screw. This ensures quick and attractive installation. A separate trim plate is not required. Speaker terminals accept up to #12 AWG (2.5mm2) wire for polarized connections. Strobe connections are made to color-coded wire leads. Life safety strobes are shipped with standard wall mount style FIRE lens markings. Where ceiling orientation, other languages, or different lens markings are required, Kidde offers optional LKW and LKC series Lens Marking Kits. These optional lens markings simply snap on to the strobe. Integrity strobes are designed for 16 to 33 Vdc operation and must be connected to signal circuits that output a constant (not pulsed) voltage. A diode is used to allow full signal circuit supervision.
