Aux 1 Auxiliary Supply (supervised, regulated)
Aux 1 resettable auxiliary power is used to power the remote annunciators and smart relay
modules.
This filtered circuit is supervised for shorts.
A short will:
•
Disconnect the power until the “RESET” button is pressed.
•
Generate a trouble signal
The circuit must be supervised for opens utilizing the End of Line Relay Model EOLR-1(A) as
shown in Figure 15. This supply is rated at 24VDC regulated/500mA max/1V voltage drop
maximum.
Unfiltered Supply (unsupervised, unregulated)
This unregulated supply is not supervised. When supervision is required, the circuit must be
supervised for opens utilizing the (UL listed - S3705) End of Line Relay Model EOLR-1(A).
This supply is rated at 24V FWR/1.7A max. If there is a short on this circuit, the auxiliary power
does not recover automatically when the short is removed. The main power and the battery
must be disconnected, then reconnected and the panel reset to re-establish the auxiliary
power supply.
