Connect the alarm input/output terminals to external devices such as sensors and buzzers.

1 Loosen the screws on both edges of the terminal block using a flathead screwdriver, followed by dismantling it as shown in the left diagram.

2 Strip the coating of the alarm signal cable by about 4mm before inserting it into the terminal.

3 Turn the screw on the side to fasten the alarm signal cable.

4 Upon fastening the alarm signal cable, re- install the terminal block that has been dismantled in Step 1.

Note

Cable Specifications

50 m or shorter in length UL1007, UL1015 or equivalent AWG#22 to AWG#18 or equivalent

Caution

Due to external noise, the cable may not function properly even when the cable length is less than 50 m. In this case, use a shielded cable or take measures such as keeping the cable away from the noise source.

This terminal is for connecting with a sensor, infrared, door or metallic, or a manual switch.
