Fire Circuits
When a zone is programmed as a fire zone, the zone becomes normally open and requires an EOL resistor. If a line short occurs or if the smoke detector becomes
active, whether the system is armed or disarmed, the control panel will generate an alarm. If a trouble occurs on a fire zone, the Fire Loop Trouble will appear in the
keypad’s trouble display (See “Trouble Display” on page 55.) and the control panel can transmit the Fire Loop Trouble report, if programmed, in section
[866]
.

AC Power
Do not use any switch-controlled outlets to power the transformer to avoid accidental user AC shut off. Connect the transformer as shown in Figure 1. Use the below
table for appropriate transformer.
Use only a safety approved transformer with rated output voltage of 16.5 Vac and rated power of 40 VA (minimum).
Backup Battery
To provide power during a power loss, connect a 12 Vdc 7 Ah or 4 Ah rechargeable lead acid or gel cell battery. Verify proper polarity as reversed connections will blow the
battery fuse.
Use only safety approved rechargeable battery with rated voltage of 12 Vdc and rated current of 7A maximum.
Battery Test
If the battery is disconnected or if the battery fuse is blown, a No/Low Battery failure will appear in the keypad’s trouble display
(See “Trouble Display” on page 55.).
This trouble will also appear if the battery’s capacity is too low or if the voltage drops to 10.5V or lower while the control panel is running on the backup battery.
At 8.5V or lower, the panel shuts down and all outputs close. A battery protection disconnect occurs at 9.1 volts. If output voltage drops below 11.3 volts, a fault
signal is generated.
Demonstration or Emergency System Power-up without an AC Source
To power-up the control panel for demonstration or emergency purposes only, use a standard 12 VDC, 4 Ah/7 Ah backup battery. To power the control panel using
a backup battery:
1.
Connect the battery to the control panel's
BATT
terminal.
2.
Use a wire to short the battery's negative terminal to the panel's
AUX
-
terminal.
