Conventional Fire Alarms Pull Stations 270 Series

The Edwards 276B/277B series non-coded, single-action fire alarm stations are UL listed, contemporary-styled Lexan stations. The 276B series feature terminals for field wiring connections, and the 277B series use 6" (150mm) wire leads for field wiring connections.

All types are available with single 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 is 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 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). For surface mounting use a 276B-RSB surface back box.
