2. Simulate activation of the Manual Call Point (if fitted)
 The “MCP Alarm Activated” LED flashes
 Monitored 24V
DC

in the Main Control board.
2. Simulate Monitored Valve alarm input by bridging the Monitored Valve input
terminals (MV/IN)
 “Monitored Valve Tamper” red LED flashes
 Monitored 24V
DC
Monitored Valve alarm output is activated if the output is
not disabled
