draw, and include on worksheet.
‡
Figures are for relays OFF/relays ON.
In UL installations, maximum current draw from the Auxiliary Output and the Alarm Output combined
**
must not exceed 600mA.
1. Use the battery standby formula (shown on previous page) to select the
appropriate battery for the installation.
Remember, when calculating the battery size needed, you must add the
100mA drawn by the control itself to the total Auxiliary current draw in the
worksheet below.
Do not connect the battery until all devices have been wired to the control.
2. Attach the Red and Black wires on the battery connector cable as follows:
a) Red to the positive (+) battery tab on the control board.*
b) Black to the negative (–) battery tab on the control board.*
*
This not required if wires are already connected to the battery tabs on the control.
3. Attach the Red and Black wires at the other end of the battery connector
cable to the battery, as follows:
a) Red to the positive (+) terminal on the battery.
b) Black to the negative (–) terminal on the battery.
