2440S-15/75-R Edwards 2400 Series temporal horns and temporal horn-strobes are designed for use with compatible life safety communication and control equipment to alert occupants of a life safety event. The horn emits up to a 95dB (@ 1meter) low frequency sound, and must be connected to signal circuits that output a constant (not pulsed) voltage. A diode is used to allow full signal circuit supervision. The strobes are designed to flash at the same rate (synchronize) when used with a compatible sychronization source, such as the EG1M-RM synchronization module, E-FSC and E-FSA fire panels, and EBPS series booster supplies. The plastic housing is made from durable and fire retardant, high impact plastic with a slightly textured surface. The mounting plate firmly holds the device in place with a single screw. A separate trim plate is not required. Terminals accept up to #12 AWG (2.5mm2) wire for polarized connections. 2400 Series strobes are shipped with standard wall mount style âFIREâ lens markings. Where ceiling orientation, other languages, or different lens markings are required, Edwards offers optional 2440KTW and 2440KTC series Lens Marking Kits.
