Low Voltage / Dry Contact Switches
General Information
The GM series of low voltage dry contact switches are
available in a three wire momentary (SPDT), three wire
momentary locking (SPDT), and a two wire maintained
style (SPST). These switches can be used with any
Greengate lighting controller.
Getting Started
1. Do not discard these installation instructions. Please
keep for future reference and operation information.
2. It is recommended that all low voltage wiring be
done with power removed to the logic board to
protect components from potential shorts during the
wiring process.
3. Use only as intended and at the listed voltage.
4. All installation and service must be performed by
qualified personnel or service technicians.
5. Install in accordance with the National Electrical Code
and any other codes which may apply.
6. Installation and wiring information contained in this
document is based on industry-accepted standards
and practices. If conflicts exist between these
instructions and any applicable codes or ordinances,
please contact Greengate before proceeding with the
installation.
7. High voltage is present inside the lighting enclosure.
Use extreme caution when performing maintenance
on this equipment.
8. Document all wiring and device terminations and
locations so that devices can be properly configured
and programmed for operation.
Mounting Detail
1. Rough-in the appropriate size wall box for the switch
plate ordered.
2. Once wiring is complete, install the switch into the
wall box with the provided screws.
3. Mount the switch face plate to the wall switch with
the provided screws.
Wiring Detail
All low voltage wiring is Class 2 wiring and must enter
the lighting controller enclosure through the low voltage
section of the enclosure. All low voltage wiring must be
run in separate conduit from line voltage wiring. Failure to
separate high voltage from low voltage wiring may cause
interference with logic board function.
For all momentary SPDT switches, cabling should be 18
AWG twisted, three-conductor, unshielded cable. For all
maintained SPST switches, cabling should be 18 AWG
twisted, two-conductor unshielded cable. Maximum
length for dry contact closure device wiring is 1000 feet.
