1.1.1 Relay Tests (Test - Address 000-127)
Diagnostic Menu
This function tests the connection of the Command Module or detector to an alarm panel by operating the
alarm or fault relay currently selected. Assuming proper connection, this should give appropriate
indications on the fire panel. The test runs through the sequence
Aux –> Pre-Alarm + Fault –>
Fire 1 + Fault –> Fire 2 + Fault –> Fault
, stepping to the next test on the list when
<ENTER> is pressed. Although the relevant relays are activated at each stage, the associated lights on
the front panel are not illuminated or recorded in the event log.
1.1.1 Watchdog Trip Count (Display)
Diagnostic Menu
The watchdog is a circuit built into the controller that restarts the controller in the event of a failure to
function properly. This could be as a result of electrical spikes. This count shows the number of
interruptions found and the details of each problem can be found in the event log (see section
185619544.01.1.1 “View Event Log (Display - Address 000-127)” on page 25 and section 8 “Event Log”
on page 44).
