8.8 Auxiliary Power Supplies
8.8.1 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 17. This supply is rated at 21.1 VDC regulated / 300 mA max / 1 V
voltage drop maximum.
8.8.2 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 17. This supply is rated at 21.1 VDC regulated / 500 mA max / 1 V voltage
drop maximum.
8.8.3 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 17. This supply is rated at 24 VDC / 1.7 A 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.
