2452THS Series
Field Programmable
Electric Horn/Strobe
 Edwards is a registered trademark of UTC Fire & Security


The Edwards 2452THS Series temporal horn/strobe are especially designed for use with compatible life safety communication and control equipment to alert occupants of a life safety event. The horn emits a piercing low frequency sound that is easily heard above moderate ambient noise levels. The flash from its strobe can be noticed from almost any position in the room, corridor or large open space.

Its rugged plastic housing is made from durable and fire retardant, high impact plastic with a slightly textured surface. Its ingenious mounting plate firmly holds the device in place with a single screw.

HORN: During installation, the horn is configured for steady or temporal tone signal and either low (94dBA) or high (98dBA) output. When temporal output is selected, all horns on a common two-wire circuit are self-synchronized. External control modules are not required for audible synchronization.

STROBE: The strobe exceeds UL synchronization requirements (within 10 milliseconds over a two-hour period) when used with a separately installed EG1M Signal Master. Fully compatible with Genesis signals.

Synchronization is important because a small portion of the population have a condition which may cause them to become disoriented from multiple random flashes of light. This strobe minimizes the risk.

The 2452THS horn/strobe is for use in rest rooms, meeting rooms, lobbies, hallways, sleeping rooms or work areas intended for use by the hearing impaired, or any area where a visual alarm signal is required.
