Wiring Technique
CAUTION
•
HVAC units may contain AC mains power. To prevent electric shock, ensure that AC mains is OFF before
connecting with HVAC units.
•
Do NOT take shortcuts when connecting the HVAC power circuits.
Wiring Techniques
Conceal the sensor wiring by “fishing” the wire from hollow wall or partition.
Drill an adequate hole behind the sensor, so that the sensor can cover the hole.
Drop a string with a small weight inside the wall to bottom.
Drill another hole on wall at the carpet level. Use a stiff wire with a hook to pull the string out from the hole.
Pull the cable to the door switch, HVAC unit and slave sensor, if necessary
Use proper tool to tuck the wire under the edge of carpet.
Alternatively, staple the wire in the corner and cover it with vinyl corner molding to match room decor.
Wiring should be completed and concealed in a manner that it will not be damaged by hotel guest or housekeeper.
Mount the Sensor (GH-MS1)
1. Remove the sensor cover by releasing the locking screw at the bottom of the housing.
2. Carefully remove the circuit board by releasing the fixing screw.
3. For corner mount (recommended), use the mounting holes on both 45° slopes to mount the base.
4. Lead the cable into the base. Replace the circuit board on the base and fixed with screw.

Mounting Guide
Mount the sensor without bracket
1. Open the front cover by loosening the locking
screw.
2. Remove the PCB from the bottom case with
care.
3. Mount the bottom case on the wall with proper
knockout holes.
4. Lead the cable into the case and replace the PCB
for wiring connection
Mount the sensor with bracket
1. Mount the base of mounting bracket on the
selected position as shown.
2. Lead the cable through the central tunnel of
mounting bracket.
3. Open the front cover by loosening the
locking bolt. Lead the cable into the case and
fix the mounting
bracket with the bottom case of sensor.
4. Connect the cable to the corresponding
terminals.
