Double-Action

Fire Alarm Stations

278/279B Series — Non-Coded

Overview

The Edwards Cat. No. 278B/279B 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. 278B series are double action stations with terminals

for field wiring connections.

The Cat. No. 279B series are double action stations with six inch

(150mm) wire leads for field wiring connections.

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 tool (depending on station selected) is

required to reset mechanism. See specification chart for specific

catalog numbers and features. 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 ap-

plicable 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). For surface mounting use a

Cat. No. 276B-RSB surface back box.
