Termination Diagram
To connect the wires between GH-MS1 and other components of the system, the terminals of GH-MS1 should be connected with correct
wire to ensure optimum performance. Each terminal block of GH-MS1 are described as follow in the left to right sequence.
SLA
This terminal and terminal “GND” are for connection with the N.O. output of slave sensor. If multiple slave sensors are used,
the connection should be made in parallel.
GND
This ground terminal normally pairs with SLA or DSW for connection of slave sensor or door switch.
DSW
This terminal and terminal “GND” are for connection with the door switch. If multiple door/window switches are used, the
connection should be made in series.
-OCC+
These two terminals provide occupancy status output for guest-in-room detection.
-24V+
These two terminals are for the input of 24V power supply from power pack.
NC
This terminal and terminal “COM” form the Normally Closed (NC) output of GH-MS1.
COM
Common pole of relay output.
NO
“NO” and terminal “COM” form Normally Open (NO) output of GH-MS1.
