Fire-Lite BAT-121000 — a single 12 V, 100 Ah sealed lead-acid battery for fire alarm secondary power.
Fire-Lite specifies BAT Series cells as the standby power source for its fire alarm control equipment, and this is the largest single block in that series. It is reached for when the 24-hour standby plus alarm calculation outgrows the 18 Ah and 26 Ah cabinet batteries. Panels use two 12 V blocks in series for a 24 V bus.
- 12 V, 100 Ah at the 20-hour rate (5.0 A to 10.8 V)
- Fire-Lite BAT-121000 is the Power-Sonic PS-121000
- Sealed, maintenance-free, overcharge protected, high-impact case
- 12" (305 mm) wide × 6.6" (168 mm) deep × 8.2" (208 mm) high; 8.98" (228 mm) over the terminals
- Weight 68 lb (30.84 kg)
- UL Recognized Component MH20845; UN2800 non-spillable
This is one battery, not a pair, and at 68 lb it is heavy — check your cabinet depth and shelf rating first. Confirm the terminal style your harness needs, as the PS-121000 is built in more than one terminal configuration.
