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.
