The Kidde 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 in. (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.
