EDWARDS 2453BSA are indoor bell/strobe adapter plates that come equipped with an electronic strobe signal and have provisions for mounting a fire alarm bell. The units are intended for indoor use only with compatible fire protective signaling systems. The strobes are self-synchronized to flash at 1 fps across their full operating voltage range. The strobe operates on any existing 2-wire signal circuit. Separately installed "sync control modules" are not required.

Installation Instructions for Bell/Strobe Adapter Plate
CAUTION
Electrical supervision requires wire run to be broken at each device.
Do not loop signaling circuit field wires around bell/strobe leads.
3. See Figure 2 for wiring connections. Use wire nuts (not provided) to
connect wires. The strobe must be connected to a signal circuit that outputs
a constant voltage. Polarity must be observed for the unit to function
properly. Figure 2 details wiring for connecting the bell and strobe to the
same circuit or to separate circuits.
For additional wiring connection details, see the applicable installation
instructions for the signaling modules or circuits used in the fire alarm
control panel.
4. Mount the bell/strobe adapter plate to the electrical box using the 3/4" (19
mm) phillips head screws provided.
5. Mount the bell onto the adapter plate and fasten the assembly to the
electrical box with the screws provided with the bell.
6. Replace the gong and fasten with the gong support bolt.
7. Apply power and activate the unit to verify that it is operating properly.
MAINTENANCE
CAUTION
Should the unit fail to operate, do not attempt repair. Contact the
supplier for replacement.
Perform a visual inspection and an operational test twice a year or as directed
by the local authority having jurisdiction.
DESCRIPTION
The bell/strobe adapter plates come equipped with an electronic strobe signal
and has provisions for mounting a fire alarm bell (not supplied). The units are
intended for indoor use only with compatible fire protective signaling systems.
The strobes are self-synchronized to flash at 1 fps across their full operating
voltage range. Studies show that people with photosensitive conditions may
experience a photoconvulsive response from multiple random flashes of light.
This risk is minimized with these strobes. The strobe operates on any existing 2-
wire signal circuit. Separately installed "sync control modules" are not required.
The bell/strobe adapter plate is to be installed in accordance with the latest edi-
tion of NFPA 72, National Fire Alarm Code. It is recommended that these prod-
ucts be installed in accordance with the requirements in the latest recognized
edition of national and local fire alarm and electrical codes.
Synchronization of less than 200 milliseconds will be maintained for no less
than 60 hours supervision followed by 30 minutes in alarm.
See Table 1 and Figures 1, 3 and 4 for specifications.
INSTALLATION
WARNINGS
This device will not operate without electrical power. As fires
frequently cause power interruptions, discuss further safeguards with
your local fire protection specialist.
To reduce the risk of shock, always disconnect all power before
handling the unit.
To reduce the risk of shock, do not tamper with unit when circuit is
energized. Disconnect all power and allow 5 minutes for stored energy
to dissipate before handling.
1. Select any standard electrical box. Install the electrical box using suitable
hardware.
2. Bring signaling circuit field wiring into the electrical box.

NOTE: This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instruction manual, may cause
harmful intereference to radio communications. Operation of this equipment in a residential
area is likely to cause harmful interference in which case the user will be required to correct
the interference at his own expense.
CAUTION: Changes or modifications to this equipment not expressly approved by the party
responsible for compliance could void the user's authority to operate the equipment.
Same Signal Circuit
The bell and strobe can be connected to the same
signal circuit (as shown) if the circuit is configured for
continuous signal operation.
Caution: Electrical supervision requires wire run to be
broken at each device. Do not loop signal circuit field
wires around the Bell/Strobe unit leads.
Separate Signal Circuits
The bell and strobe can be connected to different
signal circuits (as shown). The strobe is designed to
be used on circuits that output a constant voltage. Do
not connect the strobe to a coded or pulsating voltage.
Caution: Electrical supervision requires wire run to be
broken at each device. Do not loop signal circuit field
wires around the Bell/Strobe unit leads.
