BC-1EQ Seismic Kit
Installation Sheet
Description
The BC-1EQ Seismic Kit is used to restrain standby batteries in a BC-1
battery cabinet, and other components in fire alarm system cabinets
when the BC-1 is used to house their standby batteries.
The kit provides cross brackets and the necessary mounting hardware,
cable ties, cable mounts, and alcohol wipes.
The table below lists the affected cabinets and shows how the BC-1EQ
is used in the cabinets.

Installation
WARNING: Shock hazard. To avoid personal injury, remove all
sources of power and allow stored energy to discharge before
installing or removing equipment.
Restraining standby batteries in a BC-1 battery cabinet
WARNING: Shock hazard. Do not touch the battery terminals with the
battery brackets when installing the brackets. Cover the exposed
terminals with electrical tape during installation. Failure to follow these
instructions can result in personal injury or equipment damage.
Notes
• Do not drill the bracket mounting holes into a knockout.
• If a 3-BTSEN Battery Distribution Bus is installed in the cabinet, do
not obstruct it when installing the bracket.
This section describes how to install the BC-1EQ Seismic Kit for the
battery configurations listed below.
Battery configuration
Description
17 Ah
Supports two 12 V, 17 Ah batteries
24 Ah
Supports two 12 V, 24 Ah batteries
40 Ah
Supports two 12 V, 40 Ah batteries
To install the battery brackets:
1. After de-energizing the unit, set the batteries in the bottom of the
cabinet and push them against the back wall.
2. Rest a cross bracket (P/N 9000842-3) across the top of the
batteries, at least 1/2 in. away from the battery terminals, and mark
the mounting holes. See Figure 1.
3. For a 40 Ah battery configuration, go to step 5.
4. For a 17 or 24 Ah battery configuration, position a cross bracket
(P/N 9000842-3) against the front of the batteries, at least 1/2 in.
below the battery terminals, and then mark the mounting holes.
5. Remove the batteries. Drill bracket mounting holes where marked,
using a number 18 drill bit.
6. Replace the batteries and install the brackets using the hardware
provided. See Figure 1.

Securing the data cable connections in 3-CAB or 3-RCC series
fire alarm cabinets
When using the BC-1 battery cabinet to house standby batteries for
3-CAB or 3-RCC series fire alarm cabinets with rail chassis installed,
you must secure the data cable connections on the rails. The
connections on the 3-CHAS7 or 3-CHASS4 chassis must be tied down
to ensure that the cables will not disconnect.
Figure 2 provides an example of how to wrap a cable tie diagonally
around two data cable connectors and the rail. If you choose a different
method of wrapping the tie, make sure you encompass the connectors.
To secure the data cable connections:
1. Wrap a cable tie over the data cable connectors and around the
rail. See Figure 2.
2. Make sure the cable tie is over the connectors and then pull it tight.
3. Cut off any excess cable tie.
4. Repeat the procedure for each rail.

Securing the SA-ETH Ethernet card ribbon cable in
analog/addressable fire alarm cabinets
Caution: Equipment damage hazard. This product is sensitive to
electrostatic discharge (ESD). To avoid damage, follow accepted ESD
handling procedures.
When using the BC-1 battery cabinet to house standby batteries for
analog/addressable fire alarm cabinets with an SA-ETH Ethernet card
installed, you must secure its ribbon cable to ensure that the cable
does not disconnect.
Figure 2 provides an example of how to secure the cable. If you
choose a different method, make sure the cable cannot move.
To secure the SA-ETH Ethernet card ribbon cable:
1. Open an alcohol wipe and clean the top of the ferrite on the
SA-ETH ribbon cable where a 1-inch square cable mount will be
placed. See Figure 3.
2. Clean an area on the cabinet rear wall for a second cable mount.
The area must be located so a cable tie can loop from the ferrite
cable mount to the wall cable mount.
3. Remove the adhesive paper from the backs of the cable mounts
and attach the mounts to the cleaned areas.
4. Thread a cable tie through the slot in the cable mount on the
ferrite, and then through the cable mount on the wall.
5. Loop the cable tie back and tighten it. Cut off any excess. Do not
overtighten the cable tie, to avoid pulling the cable mounts away
from their surfaces.
