Auxiliary power output
circuit
AUX 1 power: 500 mA (standby), 24 VDC. Up to 1000 mA of alarm current is
available on AUX 1 if you reduce the total available control panel NACs alarm
current by the amount of AUX 1 + AUX 2 alarm current over 500 mA )
AUX 2 power: 500 mA (standby and alarm), 24 VDC (resettable)
AUX 1 + AUX 2: Total maximum standby current = 500 mA
AUX 1 + AUX 2: Total maximum alarm current = 500 mA; (1000 mA is available if
you reduce the total available control panel NACs alarm current by the amount of
AUX 1 + AUX 2 alarm current over 500 mA)
Output: 28.3 to 21.9 VDC, special application
Note: For a complete list of devices that can be connected to this circuit, see the
VS1 and VS4 Series Compatibility List (P/N 3102354-EN).
