1: Battery Accessory Cabinets - Honeywell 6820 Manual

Control Panel Installation
The control panel battery charge capacity is 7 to 35 AH. Use 12V batteries of the same AH rating. Determine the correct AH rating as per the
standby load calculation (see Section 3.5).
Wire batteries in series to produce a 24-volt equivalent. Do not parallel batteries to increase the AH rating. It is recommended to replace bat-
teries every five years.
4.5.1 Battery Accessory Cabinets
Model RBB accessory cabinet can be used when your backup battery requirements use 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).
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 4.7 for the four cabinet mounting holes.
• If mounting onto drywall the accessory cabinet must be mounted onto 3/4-inch plywood. This is necessary because the weight of the
batteries inside the accessory cabinet could cause the cabinet to pull away from the drywall.
• When mounting on concrete, especially when moisture is expected, attach a piece of 3/4-inch plywood to the concrete surface and
then attach the RBB cabinet to the plywood.
• If using the battery cable extenders provided (P/N 140643), mount the RBB cabinet no more than 18" away from the main control
panel cabinet. This will ensure that the battery cables reach the battery terminals.
