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 VS1 and
VS4 Series Compatibility List (P/N 3102354-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.
• For a complete list of auxiliary/booster power supplies, refer to the VS1 and VS4 Series
Compatibility List (P/N 3102354-EN). Also refer to the REL Technical Reference Manual
(P/N 387515-EN) for a list of REL compatible power supplies, if you need to power REL
module.
