Auxiliary Power Supplies
Aux 2 Resettable Auxiliary Power (supervised, regulated)
The AUX 2 resettable auxiliary power supply is supervised for shorts, therefore a short will disconnect the power
until the “RESET” button is pressed. A trouble signal will be generated if there is a short. The circuit must be
supervised for opens utilizing the End of Line Relay Model PAM-3 as shown in Figure 15. This supply is rated at
21.1VDC regulated/300mA max/1V
voltage drop maximum.
Auxiliary Supply (supervised, regulated)
Supervised auxiliary power is used to power the remote annunciators and smart relay modules. This filtered circuit
is supervised for shorts, therefore a short will disconnect the power until the “RESET” button is pressed. A trouble
signal will be generated if there is a short. The circuit must be supervised for opens utilizing the End of Line Relay
Model PAM-3 as shown in Figure 15. This supply is rated at 21.1VDC regulated/500mA max/1V voltage drop
maximum.
Unfiltered Supply (unsupervised, unregulated)
This unregulated supply is not supervised. When required, it is recommended that the circuit be supervised for
opens utilizing the (UL listed - S3403) End of Line Relay Model PAM-3 as shown in Figure 15. This supply is rated
at
24VDC/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.
