General Prohibitions  Prohibition to Dismantle the Unit
General Precautions
WARNING
(Negligence could result in death or serious injury to 
people)
1.  Do not connect any non-specified power source to the 
V, V terminals, and do not install two power supplies in 
parallel to a single input. Fire, damage to the unit, or 
system malfunction could result.
2.  The unit is not explosion-proof. Do not install or use 
near gases or flammable materials. Fire or explosion 
could result.
3.  Do not dismantle or alter the unit. Fire or electric shock 
could result.
4.  Do not allow the wires or DC output terminals to be 
shorted. Fire or electric shock could result.
5.  The unit must be installed and wired by a qualified 
technician.
CAUTION
(Negligence could result in injury to people or damage 
to property)
1.  When mounting the unit on a wall, install the unit in a 
convenient location, but not where it could be jarred or 
bumped. Injury could result.
2.  Do not install or make any wire terminations while 
power supply is plugged in. It can cause electrical 
shock or damage to the unit.
3.  Before turning on power, make sure wires are not 
crossed or shorted. Fire or electric shock could result.
4.  Do not install the unit in any of the following locations. 
Fire, electric shock, or unit trouble could result.
  *  Places subject to dust, oil, chemicals, hydrogen sulfide 
(hot spring).
  *  Places subject to moisture and humidity extremes, 
such as bathroom, cellar, greenhouse, etc.
  *  Places where the temperature is quite low, such as 
inside a refrigerated area or in front of air-conditioner.
  *  Places subject to steam or smoke (near heating or 
cooking surfaces).
  *  Where noise generating devices such as dimmer 
switches, invertor electrical appliances, are closeby.
GENERAL PRECAUTIONS
1.  This product, being a control unit of door release, 
should not be used as a crime-prevention device.
2.  This product is weather-resistant, but do not spray 
high-pressure water on it. Unit trouble could result.
3.  The product becomes inoperative during power failure.
4.  As to other manufacturer's devices, such as sensor, 
door releases, timer, used with this system, comply 
with the Specifications and Warranty conditions 
manufacturers or venders present.
5.  Keep the intercom wires more than 30 cm (12 inches) 
away from AC 100-240 V lines, particularly AC lines for 
invertor electrical appliances. Noise and malfunction 
could result.

connected. To determine the operating range, 
please refer to the specifications of each 
terminal.
(*1)  Use a separate power supply for the GT-AC, not 
the ones used to power the system.
(*2)  Two relays can be activated from GT-AC. 
However, only one relay can be activated from a  
residential station.

  External output setting
The alarm or security system connected to the terminal of relay 2 will be 
activated when the "Lockout" * or the forced entry* is carried out.   
* "Lockout": Refer to VIII below. *Forced entry: This function is linked with 
the door open/close sensor (N.C.) which is connected to PB2 and C, and 
carried out when opening the door without activating this unit. (For example, 
entry in an improper manner, manual unlock, etc.)
) If there is a way to open the door without activating this unit, such as 
manual unlock, do not make the external output setting for the forced entry.

If several incorrect access codes are attempted, the code input function is 
disabled for a programmed period of time.
·   When "Lockout" is activated, the LED (Orange) indicator and the keypad 
blink, and the buzzer sounds for 3 seconds. This is just a sound to inform 
you that the function has been activated. It is not a warning sound. If you 
want a warning to be sounded, please use the external output function to 
activate a commercially-available alarm device.
·  The unlock function will work when the request to exit/entry button is 
pushed, even while the "Lockout" function is operating.

 Auto-relock (Anti-tailgate)
After the door has been linked to the door open/close sensor (N/C), and 
unlocked, it will relock itself one second after being closed, thus preventing 
the entry of an unauthorized third party.

  Timer-linked unlocking setting
The system can be set to unlock the door by pressing the  key within 
the set time and linking it to the external timer (N/O). The operations for the 
LEDs and the buzzer after unlocking are the same as those used to perform 
user code unlocking. When the door is linked to the timer, unlocking can be 
performed using the user code and the request to exit/entry button. When 
latch output is performed for the relay settings, the relay turns ON/OFF 
every time the 
 key is pressed.

•  The setting can be saved even when the power is off. 
•  The system cannot be switched to the setting mode while the relay is unlocked.
•  When the setting mode has been activated and no operations are performed for approximately 120 seconds, the system 
will exit the setting mode. (If a key is pressed during that time, the timer will start over.)
•  Neither the request to exit/entry button nor the timer-linked unlocking 
 key can be operated, and unlocking using the 
user code cannot be performed while the setting mode is activated.
•  The volume (the check tone, operation tone, etc.) from the main unit may become lower according to the mounting status.
1 : When the auto-relock is used, the request to exit/entry button for relay 2 cannot be used. The output of relay 2 is 
only possible when user code unlocking is performed.

Input the master code twice.
(Default:                                                                )
The result of each operation is indicated by the 
lighting up of the LED indicators on the upper section 
of the unit, and by the sounding of the buzzer.
- 
When the         key is pressed, the green LED lights up, the buzzer beeps twice, and the system exits the setting mode. 
(If the         key is included in the user code and the master code, the system does not exit the setting mode.) 
- You can continue the setting up operation by entering an arbitrary setting code.
