Chapter 4: Testing and troubleshooting
GSA-REL Technical Reference Manual 47
Verify that the ‘Prerelease_1’ and ‘Prerelease_2’ LEDs extinguish after a panel
reset. If not, a second Reset switch activation may be necessary.
Avoid using the Drill switch to test the GSA-REL. If you activate a Drill, press the
Reset switch to deactivate it. The deactivation of the Drill switch, alone, does not
silence the prerelease tones.
Testing MIR2 systems
Allow the system sufficient time to stabilize after the initial startup or download.
Before you test the system, access the SDC Status tool in the MIR2-SDU. Do not
test the system if the status LEDs indicate activity that is in progress or pending.
This includes:
• Mapping
• Device new starts
• Resets
• Restarts
Testing QuickStart systems
Allow the system sufficient time to stabilize after the initial startup or download.
Before you test the system, check the Status tab of the Signature Series
Configuration Form in the QS-CU. Do not test the system if the counters or
Current Status messages indicate activity that is in progress or pending.
Connecting the releasing solenoids
Caution: Do not connect the releasing solenoids until the system has been
programmed and tested, and the Signature loop controller and GSA-REL have
reached their normal state. Failure to follow the instructions given below can
result in unexpected release of the fire suppression agent.
Follow these steps before you connect the releasing solenoids.
Before you connect the releasing solenoids:
1. After connecting all devices to the Signature data line (including the GSA-
REL), verify that you have downloaded the database to the correct panel and
Signature loop controller.
2. Using your SDU or CU, browse to the Signature Series status tool. Verify that
the loop is in its normal, inactive state.
