Description

The Edwards 279B-1110 series non-coded fire alarm stations are contemporary styled Lexan stations and are flexibly designed to meet a wide variety of application requirements and operational sequences. Also, the Edwards Est 279B-1110 series is a double-action station with six-inch (150mm) wire leads for field wiring connections.

In general, all types are available with single or double pole alarm contacts, which can be normally open, normally closed, or a combination of both. Either a key or a tool (depending on the station selected) is required to reset the mechanism. Where a manual station is installed on a circuit that also includes smoke detectors, a resistor may 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’s. 276-R and 276-RT series resistor kits permit field installation of the series resistor on applicable stations.

For semi-flush mounting, use a standard North American four-inch square box with a single gang plaster cover having an overall minimum depth of 2-1/4 inch (57mm). Besides, for the surface, mounting uses a Cat. No. 276B-RSB surface backbox.
