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 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 10 amp total alarm current.
(example: AUX1 = 1 amp, AUX2 = 1 amp, outputs up to 8 amp).
