SIGA-REL fault messages on EST2 panels
WARNING: Disconnect all wiring on TB4 of the SIGA-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 SIGA-REL circuit. This is a normal indication,
and it should go away within minutes. Table 21 lists the indications you may see
for the SIGA-REL on the 2-LCD.
