Relay contact rating 1 Amp @ 24 VDC resistive
0�0 to 20�0 mA (Non-isolated source or sink, user selectable)
0�0 mA (<0�6 mA) = Fault
2�0 mA (±0�6 mA) = Dirty window
4�0 mA (±0�6 mA) = Normal, safe (no fault, no fire)
2, 3
Analog current output
8�0 mA (±0�6 mA) = Background IR
12�0 mA (±0�6 mA) = Background UV
16�0 mA (±0�6 mA) = Fire alarm
20�0 mA (±0�6 mA) = Verified fire alarm
Screw terminal wire sizes 12 AWG to 22 AWG (2�50 mm to 0�762 mm; use stranded
conductors, not solid core)

If the "verify time" is not zero, the alarm level = 16 mA and the verify level = 20 mA� If the verify time
is zero, alarm level = 20 mA and the verify level = 20 mA�
