Power Terminals - Secondary

3.2.1

Secondary (DC) Power

A 12 V, 7 Ah (up to 14 Ah) sealed lead-acid rechargeable battery supplies secondary power for
auxiliary and alarm outputs, and powers the system during interruptions in primary (AC)
power.
WARNING!
Use Lead Acid Batteries Only: The charging circuit is calibrated for lead-acid batteries. Do not
use gel-cell or nicad batteries.
Extra Batteries Increase Back-up Time
To increase battery back-up time, connect a second 12 V battery in parallel to the first battery.
Use a D122 Dual Battery Harness to ensure proper and safe connection. Refer to the Standby
Battery and Current Rating Chart in the D9412GV3/D7412GV3 Approved Applications
Compliance Guide (P/N: F01U143069) or in the D7212GV3 Approved Applications Compliance
Guide (P/N: F01U143080) for battery standby time calculations.
D1218 Battery
The D1218 is a 12 V, 18 Ah battery for use in applications requiring extended battery standby
time. Up to two D1218 batteries can be connected when used with a D122 Dual Battery
Harness.
WARNING!
When connecting two D1218 Batteries to the control panel, both must have the same capacity
(use two 17.2 Ah batteries or two 18 Ah batteries).
NOTICE!
When using two D1218 batteries, use a separate enclosure, a D122L Dual Battery Harness,
and long leads.

WARNING!
High current arcs are possible. The positive (red) battery lead and Terminal 5 can create high
current arcs if shorted to other terminals or the enclosure. Use caution when working with the
positive lead and Terminal 5. Always disconnect the positive (red) lead from the battery
before removing it from Terminal 5.
WARNING!
The battery terminals and wire are not power limited. A 6.4 mm (0.250 in.) space must be
maintained between the battery terminals, battery wiring, and all other wiring. Battery wiring
cannot share the same conduit, conduit fittings, or conduit knock-outs with other wiring.
Refer to Figure 3.1, Page 18.
