In the MIR2-SDU choose Tools > Signature Series > Status, then select the
Current Status tab. All LEDs should be off.
In the QS-CU choose Configure > Cabinet, then select the Cards tab. Select
the Signature loop controller card, then choose Configure to open the
Signature Series Configuration Form. Select the Status tab. In the Mapping
Progress group, the Expected and Actual numbers should match.
3. Check the DS1, DS3, and DS7 LEDs on the GSA-REL to make sure that it is
not active. There should be no red or yellow LEDs. Check the output
terminals with a voltmeter prior to connecting the releasing solenoids. The
voltage should be 10 VDC or less.
When all yellow and red LEDs are off and all output voltages are 10 VDC or
less, it is safe to connect the releasing solenoids to the RELA-EOL relays.
Note: When testing the system, make sure that it is safe to do so and that testing
will not result in the release of agent.
GSA-REL fault messages on MIR2 panels
WARNING: Disconnect all wiring on TB4 of the GSA-REL (release circuits 1
and 2) when servicing the system. Disabling points does not prevent activation of
the release circuits. Failure to follow these instructions may result in loss of life,
serious injury, or property damage.
After the successful completion of the programming process, the fire alarm
control panel resets itself. Upon reset, device supervision may cause the panel to
generate a Dev/Line fault for each GSA-REL circuit. This is a normal indication,
and it should go away within minutes. Table 19 lists the indications you may see
for the GSA-REL on the 2-LCD.
