Maintaining the Alarms
The smoke alarms are designed for easy field service and
maintenance. When installed and used properly, they
require minimal maintenance.
The smoke alarms should be tested weekly. See Testing
the Alarms Sensitivity and Smoke Testing the Alarms.
When an alarm requires maintenance, it extinguishes its
LED and sends a signal to the control panel as described
in the following table.
