Greenheck Test Switch (474102) - Manual

Greenheck Test Switches (GTS-1, GTS-3, and GTS-4) are
used in dynamic smoke management systems containing
Combination Fire Smoke, Smoke, or Fire Dampers.
GTS-1
The GTS-1 can be used with combination fire smoke
dampers equipped with Greenheck’s TOR option. It has a
red indicator light to show that the damper is in the closed
position and green indicator light to show that the damper
is in the open position. The GTS-1 also has a three position
control switch with the following options:
• Normal position - power is routed to the actuator
through the primary, low-temperature, thermostat
• Closed position - power is cut to the actuator closing the
damper
• Override position - power is routed to the actuator
through the secondary, high - temperature, thermostat.
This position is used to reopen the damper for smoke
control purposes after the damper’s primary thermostat
has tripped and closed the damper. The damper will
close when the secondary thermostat’s temperature
is reached, when a smoke detector senses smoke or
when power is cut by a smoke or building management
system.
GTS-3
The GTS-3 can be used with combination fire smoke
dampers equipped with Greenheck’s RRL/OCI option
or with smoke dampers equipped with Greenheck’s
OCI option. The GTS-3 has the same red indicator light
to show that the damper is in the closed position and
green indicator light to show that the damper is in the
open position as the GTS-1. It also has a push-button
momentary switch that can be pushed and held in place to
cut power to the actuator and close the damper. When the
button is released power flows back to the actuator and
opens the damper.
GTS-4
The GTS-4 can be used with combination fire smoke
dampers equipped with Greenheck’s RRL/OCI option or
with smoke dampers or multi-blade fire dampers built with
Greenheck’s OCI option. The GTS-4 has the same red
indicator light to show the damper is in the closed position
and green indicator light to show that the damper is in the
open position as the GTS-1.
