Isolated Spdt Alarm
Terminals (Optional)
Alarm 3A at 24 volts, or 1A at 120 volts, in a suitable wiring enclosure.
a
When ignition is connected to terminal 3, terminal 4 cannot be used.
NOTE: Allowable inrush can be up to ten times the pilot
duty rating.
Example:
Pilot duty rating = 125 VA.
At 120V, running current is 125/120 = 1.05A.
Maximum allowable inrush is 10 times 1.05 = 10.5A.
