SETTING THE ADDRESS 

Each sensor must have it’s address set before system operation. 

Using the installation plan which shows the proper location for each sensor, find the address for the sensor to be installed. 
Ensure that the address and location on the plan match correctly. 

Address is set to 127,when shipping from a factory. 

For address setting, use the address programmer and write the number on the label of the sensor after setting. 

Address must be set within the address setting range of the connected panel. 

When address changing, renew the number on the label. 

See the instruction manual of the Hand Held programmer(TCH-B100/TCH-B200) about detail of setting method. 

WIRING 

The wiring diagram for the analogue sensor base should be made as shown in Fig. 2.

HOW TO USE OF SENSOR HEAD REMOVER 

1) In case of sensor head mounting to the base.

a) Adjust the remover for sensor sizes.
b) Grip sensor and push

 

the sensor to the sensor base softly.

c) Twist clockwise for secure fitting of the sensor head and base.

2) In case of sensor removal from the base.

a) Adjust the remover for sensor sizes.
b) Grip sensor, twist counterclockwise and pull down for removal of the sensor head from the base.

HOW TO USE THE TAMPER LOCK OF THE SENSOR 

1) Take any sensor and turn it over to view the bottom as shown in Fig. 3.
2) Using a small slot type screw driver break the prong as shown in Fig. 4.
3) Mount the sensor to the base bringing seams of the sensor and base into line for secure tamper locking (see Fig. 5).

HOW TO REMOVE THE TAMPER LOCKED SENSOR 

1) Take a small slot screw driver and insert it into the larger hole on the outer rim of the sensor (see Fig. 6).
2) While pushing the tab down rotate the sensor counter clockwise enough to clear the base security locking tab.

Only use enough force to remove the sensor.
CAUTION: DO NOT USE EXCESSIVE FORCE WHEN UNLOCKING THE BASE SECURITY LOCKING TAB
