Changing detector alarm sensitivity
Your fire alarm system can be programmed with two different alarm sensitivity
settings. The alarm sensitivity setting determines how easily automatic fire
detectors can sense a fire alarm condition. Typically, the primary alarm sensitivity
setting is programmed for daytime operation and the alternate alarm sensitivity
setting is programmed for nighttime and weekend operation.
To activate the alternate alarm sensitivity settings:
1. From the Main Menu, choose Activate.
2. Choose Alt Sensitivity.
3. Enter the access level password.
To restore the primary alarm sensitivity settings:
1. From the Main Menu, choose Restore.
2. Choose Primary Sensitivity.
3. Enter the access level password.
Changing event message routes
Your fire alarm system can be programmed with a primary message route and an
alternate message route. The message route setting determines where event
messages are displayed. Typically, the primary message route is programmed
for daytime operation and the alternate message route is programmed for
nighttime and weekend operation.
In most applications, a time control is used to automatically switch event
messages over to their alternate route setting. When the time control is restored,
event messages are automatically switched back to their primary route settings.
To activate alternate message routing:
1. From the Main Menu, choose Activate.
2. Choose Alt Message Route.
3. Enter the access level password.
