The theft deterrent system is not in the alarm
sounding state (common to active arming
mode and passive arming mode).



The panic alarm control is not operating (the
alarm is not set off).

Conditions that cause the panic alarm control to
shut off the alarm:
The panic alarm control shuts off the panic alarm
when any of the following conditions is met during
panic alarm operation.



The ignition switch is turned ON.



Any of the switches on the wireless transmit-

The panic alarm ends (60 seconds have
passed).

SWITCH TO THE ACTIVE ARMING MODE

HINT:
In each state of the passive arming mode, when the switch
condition transferring to active arming mode (disarmed state of
active arming mode 

→

 arming preparation state of active arm-

ing mode) is satisfied, the system will switch to each state of the
active arming mode. In this case, the active arming mode will
continue until the system switches to the disarmed state.

OPERATE GLASS BREAKAGE SENSOR

HINT:
The glass breakage sensor functions only during the active
arming mode.
(a)

If the glass breakage sensor detects that the glass is bro-
ken (1st time), the sensor will set off an alarm for 20 se-
conds (pre–alarm). If the glass breakage sensor detects
that the glass is broken furthermore (at 2nd time), the sen-
sor will set off an alarm for 60 seconds.

HINT:
If the 2nd detection is performed during the pre–alarming time
(20 seconds), the sensor will continuously set off the 2nd alarm.
At this time, the total alarming time of the 1st alarm (pre–alarm)
and 2nd alarm is 60 seconds.
(b)

The sensitivity of the glass breakage sensor can be ad-
justed by the volume switch in the glass breakage sensor.

HINT:
Because the glass breakage sensor has a high sensitivity, it
might set off a wrong alarm if the volume switch is adjusted too
high.
