Note: Unit is equipped with two (2) 1 amp max. auxiliary outputs: “AUX1” will automatically disconnect when AC

is lost. “AUX2” will remain battery backed up during the power outage. For loads connected to “AUX2” please

refer to battery “Stand-by Specifications” above for ratings. When loads are connected to the “AUX1” and/or

“AUX2” outputs during alarm condition, the remaining outputs may not exceed 8 amp total alarm current.

(example: AUX1 = 1 amp, AUX2 = 1 amp, outputs up to 7 amp).
