Refer to Fig. 5 on page 5 for wiring of the OCI option. 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). When the temperature of the secondary sensor is exceeded the damper closes and remains closed thereafter (Fig. 6) 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 page 6, Fig. 6 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.

(see Fig. 7) • 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. 8) • All construction and fasteners must meet the requirements of the appropriate wall design (See UL Fire Resistance Directory) and/or local codes.
