If any door is opened in the armed state, entry delay will occur
for 14 seconds.
During this time, the mode transfers to disarmed state if the

(b) Answer back:
The buzzer and taillights respond as answer back under
the following conditions.
(1) When the system is set:
Arming preparation is set from disarmed state using
the wireless door lock, the buzzer and taillights.
(2) When the system is released:
Disarmed state is set from either arming prepara-
tion, armed state or alarm sounding using the wire-
less door lock, the buzzer and taillights.
4. PANIC ALARM CONTROL
(a) The panic alarm control makes it possible for you to volun-
tarily set off the panic alarm by pressing the PANIC switch
on the wireless transmitter. However, this control oper-
ates independently from the alarm control by the theft de-
terrent system (switched to the alarm sounding state from
the armed state).

(1) Conditions that cause the panic alarm control to set
off the panic alarm:
The panic alarm control sets off the panic alarm by
pressing the PANIC switch on the wireless transmit-
ter under the following conditions.
The ignition switch is OFF.
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).
(2) 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-
ter (PANIC/LOCK/UNLOCK) is pressed.
The panic alarm ends (60 seconds have
passed).
The theft deterrent system switches to the
alarm sounding state (common to active arm-
ing mode and passive arming mode). Condi-
tions for canceling the panic alarm are the
same as for the alarm control.
HINT:
Active arming mode: See step 2
Passive arming mode: See step 3

6. 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.

7. 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.
