Structure and Installation
1) Fix the base onto the wall. The pitch of holes is 60mm.
2) Use a dedicated electronic encoder to set its address (1-200).
3) Signal lines use ZR-RVS-2×1.5mmtwisted pair cable. Terminal L1 and L2 connect to the cable.
4) Check the wiring first. Mount the sounder beacon on the base after that to prevent product damage from possible false wiring.

Structure and installation dimensions:

•  Secure the wiring to prevent loose contacts that may cause inactivation.
•  A single loop can connect to up to 30 sounder beacons.
