Edwards 276B-1120 Pull Station, Noncoded, Single Action

The Edwards Cat. No. 276B/277B series noncoded fire alarm stations are contemporary styled Lexan stations and are flexibly designed to meet a wide variety of application requirements and operational sequences. The Cat. No. 276B series are single action stations with terminals for field wiring connections. The Cat. No. 277B series are also single action stations but use 6” (150mm) wire leads for field wiring connections. 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 Cat. No. 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 Cat. No. 276B-RSB surface back box.
