Model SK-5208 Installation Manual 151204

3-7

Note: Note: All conduit and wiring connected to the SK-5208 must meet the applicable National Electric Code,

NFPA Standards, state, and local building code requirements. In all cases, the authority having jurisdic-

tion takes precedence.

3.8 Backup Batteries

The control panel battery charge capacity is 7.0 to 35.0 AH. Use 12V batteries of the same AH rating. Determine

the correct AH rating as per your current load calculation (see 3.6.2).

Wire batteries in series to produce a 24-volt equivalent. Do not parallel batteries to increase the AH rating.

Batteries larger than 18 AH (not to exceed 35 AH) use the RBB Remote Battery Box. It is recommended that you

replace the batteries every five years. The following steps and diagram explain how to connect the batteries.

1. Connect the black wire to the negative (-) side of battery #1.

2. Connect the jumper wire provided (P/N 140694) from the positive (+) side of battery #1 to the negative side

of battery #2.

3. Connect the red wire to the positive (+) side of battery #2

Warning

To reduce the risk of electrical shock, make sure that all power has been turned off or disconnected before attempting
