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 95 dB (at 1 m) 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 synchronization 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.
