2453BSA Series

The Edwards 2453BSA Series Bell/Strobe Adaptor Plate contains a

30, 15/75, or 110 candela strobe. The unit is specifically designed

for use with the 439D-AW-R series of 6" (152mm), 8" (203mm) and

10" (254mm) red fire alarm bells (ordered separately). The Adaptor

Plate is available in red.

The strobes employ a unique microprocessor design that assures

all units operate at the same time and at a rate of one flash per

second thereby reducing the risk of causing disorientation of a

small portion of the population having photosensitivity. Wire leads

are provided for easy installation of the strobe. The units are rated

for indoor use. The strobes require a continuous (non-pulsed) DC

source.

The 2453BSA Series is designed for indoor wall mounting on a vari-

ety of standard, flush mounted, North-American electrical boxes.

These include 1-gang, 2-gang, 3-1/2" & 4" octagon and 4" square

boxes. Edwards recommends that these fire alarm bell/strobes al-

ways be installed in accordance with the latest recognized edition

of national and local fire alarm codes.
