tor - The TOR (temperature override device) option
incorporates two thermostats with fixed settings (usually 165°F
and 350°F). The primary sensor (the sensor with the lower
temperature setting) can be bypassed by an external electrical
signal allowing the damper to reopen until the temperature
reaches the setting of the secondary sensor (the sensor with
the higher temperature setting). See Figure 8.
When the temperature of the secondary sensor is exceeded the
damper closes and remains closed thereafter.
The TOR assembly also contains a single pole, double throw
switch used to indicate damper blade position. The switch
provides a positive open or closed signal when used in
conjunction with remote indicator lights. See Fig. 8 for wiring of
the TOR thermostats and indicator switches.
If either the TOR or the RRL is ordered with a pneumatic
actuator, an EP switch is required with an appropriate electric
power circuit to allow the electric thermostat to control the
pneumatic actuator.
prV - The PRV (pneumatic relief valve) option is heat
responsive device used with pneumatic actuators. This can
be used in place of EP switch where a RRL is used. The PRV
activates when temperature in excess of the temperature of the
fusible link are detected. When the fusible link melts, air from
the actuator is exhausted to close the dampers. Pneumatic
actuators are to be piped per local code.
8. recommended preparation of openings in Wood
and metal stud Walls
• Frame wall openings as shown below. (see Fig. 9 & 10)
• Double vertical studs are not required for openings 36 in. x
36 in. or smaller.
• Gypsum wall board must be fastened 12 in. on center to
all stud and runner flanges surrounding opening.
(see Fig. 11)
• All construction and fasteners must meet the requirements
of the appropriate wall design (See UL Fire Resistance
Directory) and/or local codes.
