Installing the Battery
Place the battery upright in the base of the enclosure. Locate the red and black leads supplied in the literature pack. Connect the black battery lead to terminal 4, and then to the negative
Warning, High Current Arcs 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.
Replacement
Radionics recommends battery replacement every 3 to 5 years under normal use. Exceeding the maximum output ratings, or installing the transformer in an outlet that is routinely switched off, causes heavy discharges. Routine heavy discharges can lead to premature battery failure.
D8132 boosts battery backup: Adding a D8132 Battery Charger Module supports additional batteries of up to 36 Ah capacity if required.
Warning: The transformers for the D9112 and any D8132 modules connected to it must be powered from the same 120 VAC circuit. The D9112 supervises AC power by monitoring the power from the transformer connected to terminals 1 and 2. It cannot supervise the AC power for D8132 modules if their transformers are not plugged into the same AC circuit as the transformer for the panel.
Battery Supervision
When the battery voltage drops to 13.8 VDC, the yellow Charging Status LED lights. When the battery drops to 12.1 VDC the red Low Battery LED lights and the panel, if programmed for power supervision, transmits a BATTERY LOW report in the Modem II transmission format. It transmits a TROUBLE ZN 9 report in the BFSK format.
If the battery is missing or shorted, the red Low Battery LED flashes at the same rate as the green Operation Monitor LED. If the panel is programmed for power supervision, it transmits a BATTERY MISSING report in the Modem II transmission format, or TROUBLE ZN 9 report in the BFSK format.
