1X-X3 Operation Manual 17
Out of service
The control panel is out of service when there is insufficient mains or battery
power. In this state there are no further fire alarm or fault signals from detection
zones and no activation, deactivaton, or fault signals from input devices are
processed.
The out of service state is indicated as follows:
• Out of Service LED: Steady indicates that there is no mains power and the
battery power is insufficient. Flashing indicates that the mains power is
insufficient and there is no battery power.
• Supply Fault LED: Steady indicates that there is no mains power. Flashing
indicates that there is no battery power.
The control panel buzzer sounds intermittently.
When power is re-established, the control panel returns to its former status after
being reset. (The Out of Service state is latched.)
Note: When the control panel indicates out of service, the fire alarm detection in
your system is inactive and your site is not protected. Contact your installation or
maintenance contractor immediately to solve the problem.
