High strength airfoil blades ensure the lowest resistance to airflow in HVAC systems with velocities to 2000 fpm (10.2 m/s ) and 4 wg (1 kPa). Model SMD-401M may be installed vertically (with blades running horizontal) or horizontally and is rated for airflow and leakage in either direction. RATINgS Leakage Class: I Model SMD-401M meets the requirements for smoke dampers established by: National Fire Protection Association NFPA Standards 92A, 92B, 101 & 105 IBC International Building Codes ICBO

The standard mounting locations provide enough space for the mounting of actuators, controls and allow space for installation of retaining angles and duct connections. The standard location of a damper mounted in a factory sleeve ("A" dimension) is shown below. The damper can be positioned at other locations within a range of 6 in. (152mm) to 12 in.

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 exceede

Sometimes smoke can be of such quantity as to be a serious hazard to life safety unless blowers are shut down and dampers are actuated. The primary purpose of duct smoke detection is to prevent injury, panic, and property damage by reducing the spread (recirculation) of smoke. The detector samples air currents passing through a duct and gives dependable performance for management of smoke and combination fire smoke dampers. Duct smoke detection can also serve to protect the air conditioning syst

SAFEty CAUtION ! Verify power before wiring actuator. Greenheck is not responsible for any damage to, or failure of the unit caused by incorrect field wiring. SAFEty DANGER ! : to avoid causing death or serious bodily harm to building occupants, follow all instructions carefully. Dampers must close completely to preserve the integrity of the fire smoke separation. Installation - Failure to follow these instructions will void all warranties. These instructions apply to 11/2 hour rated combination

Maximum is 3000 fpm. 2. Model 2151 low profile smoke detector is mounted to a standard electrical box within the duct. The twist-in/ twist-out head allows easy removal from the base for quick cleaning and maintenance. 3. Smoke detector specifications are: Operating temperature rating: 32°F to 120°F (0°C to 49°C) Operating humidity range: 10% to 93% RH Operation voltage: 120 VAC 4.
