Edwards 279B-1120 Pull Station

The Edwards 279B-1120 series non-coded, double-action fire alarm stations UL listed, and also contemporary-styled Lexan stations. Additionally, the 278B series feature terminals for field wiring connections, and the 279B series use 6” (150mm) wire leads for field wiring connections.

All types are available with single or double pole
alarm contacts that can be normally open,
normally closed or a combination of both. Either
a key or tool (depending on station selected) is
required to reset mechanism. Where a manual
station installed on a circuit that also includes
smoke detectors, a resistor can be added in
series with the alarm initiating contacts on the
station so the operation of the station does not
extinguish alarm LEDs on operated detectors.
The 276-R and 276-RT resistor kits permit field
installation of the series resistor on applicable
stations.

For semi flush mounting, use a standard North American 4 inch square box with single gang plaster cover having an overall minimum depth of 2-1/4 inches (57mm). Furthermore, for surface mounting use a 276B-RSB surface back box.
