Edwards BC-1 Installation Sheet

BC-1(R) Battery Cabinet
Installation Sheet
Description
The BC-1(R) Battery Cabinet is used for a system requiring a battery
rated above 17 Ah. The BC-1(R) consists of a surface mount wall box
and door. The cabinet can house up to two 24 Ah or two 40 Ah
batteries.
The BC-1(R) provides an internal terminal assembly for wiring the
batteries to the fire alarm control panel power supply terminals.
Installation
Install the battery cabinet in accordance with CAN/ULC-S524
Installation of Fire Alarm Systems.
Install the battery cabinet in the same room as the fire alarm control
panel. We recommend the space between the cabinet and the panel
be 3 in. (7.6 cm) minimum and 10 ft. (3.4 m) maximum. Run battery
wiring in conduit or equivalent protection against mechanical injury.
Refer to Figure 4 for BC-1(R) cabinet dimensions.
To install the battery cabinet:
1. Attach the wall box to the wall using the mounting holes on the
back of the wall box. See Figure 1.
Use fasteners that can support the full weight of the cabinet,
including the batteries.
2. Mount the door onto the wall box by aligning the mounting holes in
the door hinge to the wall box threaded studs. See Figure 2.
3. Secure the door to the studs using the #6-32 locknuts provided.

Wiring
Connect wiring to the BC-1(R) internal terminal assembly in
accordance with applicable national and local codes, ordinances, and
regulations.
WARNING: Electrocution hazard. To avoid personal injury or death
from electrocution, remove all sources of power and allow stored
energy to discharge before installing or removing components.
Notes
• The 3-BC-1(R) internal terminal assembly (P/N 235019) can
connect to only one fire alarm control panel power supply. If more
than one power supply is required, replace the internal terminal
assembly with a 3-BTSEN or 3-BTSEN-E battery distribution bus.
For 3-BTSEN(-E) installation and wiring details, refer to the
3-BTSEN Battery Distribution Bus Installation Sheet (P/N 387337)
or 3-BTSEN-E Battery Distribution Bus Installation Sheet (P/N
3100030).
• All battery wiring must be the same length and gauge.
• If two batteries are installed in the cabinet, make sure that:
– the battery model, manufacturer, and rating is the same
– the battery date codes differ by no more than one month
To connect internal terminal assembly wiring:
1. Place the batteries inside the cabinet.
2. Wire the terminal assembly as shown in Figure 3.
