FIRE ALARM EQUIPMENT
Chime/Strobe
2457CS Series
FEATURES
> Low current draw synchronous
strobe
The Edwards 2457CS series is an audible/visual signal designed for
> Control modules not required
that is often preferred over the harsh noise of bells and horns. It is
> Red or white flame resistant
housing
often used in low ambient noise areas.
> Strobe available in 15, 30, 15/75,
and 110 candela models
all units operate at the same time and at a rate of one flash per
second.
> Chime may be pulsed up to 6
times per second
The 2457CS is designed for indoor wall or ceiling mounting. For
flush mounting use a 4" (102mm) square box with a depth of 2 1/8"
> Engineered thermoplastic
housing UL flame rated 94V-0
(54mm).
AGENCY APPROVALS
for installations that operate in conjunction with an installed fire
> Strobe - UL 1971 Listed for the
hearing impaired
alarm panel and detection devices.
> Strobe - UL 1638 Listed for
Private Mode Signaling
> Chime - UL 464 Listed for Private
Mode Signaling
use with life safety control equipment. The chime has a gentle tone
The strobes employ a unique microprocessor design that assures
The 2457CS chime/strobe is an audible/visual signaling appliance

† Insert "R" for Red or "W" for white.
Note 1: Use the mean current rating to establish the maximum number of strobes, wire gauge and standby power requirements. 2400 Series uses 24V DC. Fire Shield uses 24V DC FWR.
Note 2: From a FILTERED DC source.
Note 3: From an UNFILTERED (Full Wave Rectified) DC source.
Note 4: When chime and strobe are connected in parallel to the same circuit the currents for each must be added together.
