Battery Power

The batteries must be sealed lead acid type. Before connecting the batteries to the FACP, make certain that the
interconnect cable between the batteries is not connected. Do not connect the battery jumper cable until the
system is completely installed. Observe polarity when connecting the batteries.
Battery contains sulfuric acid which can cause severe burns to the skin and eyes and can destroy fabrics. If
contact is made with sulfuric acid, immediately flush the skin or eyes with water for 15 minutes and seek
immediate medical attention
The control panel battery charge capacity is 7.0 to 35 AH. Use 12V batteries of the same AH rating. Determine
the correct AH rating as per your current load calculation (see Section 3.7).
Wire batteries in series to produce a 24-volt equivalent. Do not parallel batteries to increase the AH rating. It is
recommended that you replace batteries every five years.

Battery Accessory Cabinet

The Model RBB Accessory cabinet can be used when your backup batteries requirements use backup batteries
that are too large to fit into the main control panel cabinet. The RBB cabinet holds batteries up to the 35 AH size.
The RBB dimensions are 16" W x 10" H x 6" D (40.64 cm W x 25.4 cm H x 15.24 cm D).

4.3.1.1 Installing the RBB Accessory Cabinet and Batteries

To properly install the accessory cabinet and backup batteries, follow these steps:
1. Mount the accessory cabinet. See Figure 4-4 for the four cabinet mounting holes.
• If mounting onto drywall the accessory cabinet must be mounted onto 3/4-inch ply-
wood. This is necessary because the weight of the batteries inside the accessory cabi-
net could cause the cabinet to pull away from the drywall.
• When mounting on concrete, especially when moisture is expected, attach a piece of
¾" plywood to the concrete surface and then attach the RBB cabinet to the plywood.
