Chapter 2: Basic operating instructions
28 VM-1 User Guide
• May not turn off visible notification appliances
• May not silence notification appliances if water is flowing through the sprinkler
system
• May automatically silence notification appliances after 1 to 60 minutes
Silenced alarm signals automatically turn back on when:
• The Alarm Silence button is pressed a second time
• Another alarm input activates
• Another alarm input in the same zone activates, unless the system is
configured to prevent it
To silence alarm signals:
1. Press the Alarm Silence button.
2. If prompted, enter the access level password.
Acknowledging events
Acknowledging an event confirms that you have seen the event message. When
you acknowledge an event, the VM-1 control panel places a check mark and the
word “Acknowledged” next to the event. On proprietary systems, you cannot
silence the panel until all events have been acknowledged.
To acknowledge an event:
1. Press the Ack/Panel Silence button.
Resetting the fire alarm system
WARNING: Risk of death or serious injury. The protected premises may be
occupied. Do not reset the fire alarm system until the proper authorities have
determined that the threat of fire is no longer present.
Pressing the Reset button restores the fire alarm system to its normal state —
provided that all latched inputs have been restored. If alarm signal initiating
devices have not been restored, active alarm signals remain active and silenced
alarm signals remain silenced.
