Auxiliary/smoke power output wiring
The control panel provides resettable and continuous AUX power output circuits. Use the
resettable AUX power output for devices such as four-wire detectors or beam detectors. Use
the continuous AUX power output for devices such as remote annunciators or door holders.
Notes
• If you do not need resettable AUX power, you can configure the resettable AUX power
output to supply continuous power.
• For a complete list of devices that can be connected to this circuit, refer to the FX-64 and
FX-1000 Series Compatibility List (P/N 3102355-EN).
Circuit specifications
• Circuit voltage range: 21.9 to 28.3 V
• AUX 1 + AUX 2 can supply 0.5 A of standby current. If more than 0.5 A of standby current
is required, you must use a power-limited and regulated 24 VDC auxiliary/booster power
supply that is UL/ULC and FM Listed (if the installation requires FM regulation) for fire
protective signaling systems.
• Continuous circuit (AUX power 1): 24 VDC nominal at 500 mA (up to 1 Amp of alarm
current is available on AUX 1 if you reduce the total available control panel NACs alarm
current by the total amount of AUX 1 + AUX 2 alarm current over 500 mA).
• Resettable circuit (AUX power 2): 24 VDC nominal at 500 mA (standby and alarm). Use
this circuit to provide 24 VDC resettable power. You can configure AUX power 2 as a
continuous circuit if you do not need a resettable circuit.
• Special application circuits
• Ground fault impedance: 0 to 5 kΩ
• Supervised and power-limited
