Testing the Installation
Test the fire control panel to confirm basic operation before connecting devices and providing
programming.
To test the installation of the Sigma A-CP Fire Control Panel:
1
Apply power to the fire control panel from the source.
2
Confirm that the Power On lamp on the fascia is illuminated.
3
Confirm that the fire control panel is not reporting trouble conditions.
4
Correct conflicts before proceeding with the testing.
5
Program and test the configuration to ensure that the control panel operates as intended.
Troubleshooting
Troubleshoot the Sigma A-CP Fire Control Panel when conflicts exist after installing or configuring.
Monitor the lower fascia indicators of the fire control panel to determine the cause of the trouble
condition. The lower indicators of the fascia are visible after opening the cabinet-door of the Sigma A-
CP Fire Control Panel.
The table below describes lower fascia indicators of the Sigma A-CP Fire Control Panel:
Indicator
Description
Mains Fail
An AC power failure exists and the fire control panel is operating on standby batteries.
Check for a loss of power at the source and then check the fuse enclosed in the
main terminal block.
Batt Fail
Standby batteries are disconnected or the charging circuit of the fire control panel has
failed. Check connections at the standby batteries. Disconnect the standby battery
leads from the fire control panel and then test for 28 V on the standby battery leads.
CPU Trbl
The central processor unit has failed to execute code and has been re-started by the
system watchdog. The watchdog reset switch must be pressed to clear the CPU
trouble condition. Press watchdog reset. If system does not return to normal then the
panel is probably damaged and needs the circuit board replaced.
Aux 24V Trbl
The 1.1 Amp fuse protecting the AUX 24 V output has operated. Power down the fire
control panel and then correct the cause of the excessive current draw. Restart the fire
control panel to reset the electronic fuse of the AUX 24 V output. The AUX 24 V output
supports a maximum current load of 500 mA during AC operation.
Reference “Operating Limits” of this section for current loading limitations of this output
that occur during standby operation.
