  When the emergency alarm switch is pressed and locked (or 

when there is a line-off activation), an alarm will sound from the 
residential/tenant station, and a warning signal will be sent to the 
guard station.

  When there is a call from the guard station, the alarm sound will 

change to a call tone.

•  The Tone off LED will flash.

  Press the TALK button to communicate with the guard station. 

The emergency alarm will sound again when communication has 
finished.

  Release the lock position of the emergency alarm switch to return 

to standby (restore the system to normal status), then the alarm 
will stop.

NOTES:  1.   On the residential/tenant station, the emergency alarm and 

call tone will be emitted at a loud (HIGH) volume, regardless 
of the volume setting.

 

2.   The emergency alarm function can be activated even when the 

system is in use. (Alarms can be activated at the same time by 
up to 5 units.)

 

3.   Residential/tenant stations within the same residence will be 

unable to receive normal calls or doorbell calls while the 
emergency alarm is sounding. It is only possible to respond to 
calls from the guard station.

 

4.   During the emergency alarm, the entrance station cannot 

make calls to the residential/tenant station or to the guard 
station that are producing emergency alarms.
