- 3-year warranty System Sensor DH100 2-wire duct smoke detector is available as either an ionization or photoelectric model. This new design allows for simplified cleaning and maintenance, or a change in application without removing the duct housing. The DH100 samples air currents passing through a duct and gives dependable performance for management of fans, blowers, and air conditioning systems, preventing the spread of toxic smoke and fire gases through the protected area. WARNING: Duct smoke detectors have specific limitations. DUCT DETECTORS ARE: NOT a substitute for an open area smoke detector, NOT a substitute for early warning detection, and NOT a replacement for a building’s regular fire detection system. Refer to NFPA 72 and 90A for additional duct detector application information. Specifications Length: 14 3/8 inches (37 cm.) Width: 5 1/2 inches (14 cm.) Depth: 2 3/4 inches (7 cm.) Shipping Weight: 3.75 lbs. (1.7 kg.) Operating Temperature Range: 23 ° to 131° F (–5° to 55° C) Operating Humidity Range: 10% to 93% relative humidity Air Duct Velocity: 500 to 4000 ft./min. *Patent pending
System Voltage: 12/24 VDC Ripple Voltage: 4 Volts peak to peak Start-up Capacitance: 0.02 µF maximum Standby Ratings: 8.5 VDC minimum
35 VDC maximum
µA maximum Alarm Ratings: 4.2 VDC minimum at 10mA
6.6 VDC maximum at 100mA
Alarm current must be limited to 100mA or less by the control panel. If used, the RA400Z remote lamp operates within the specified alarm currents. Reset Voltage: 2.50 VDC minimum Reset Time: 0.3 Sec. maximum Start-up Time: 34.0 Sec. maximum Architectural/Engineering Specifications The air duct smoke detector shall be a System Sensor Model DH100 Series Duct Smoke Detector. The detector housing shall be UL listed per UL 268A specifically for use in air handling systems. The detector shall operate at air velocities of 500 feet per minute to 4000 feet per minute. It shall be capable of local testing via magnetic switch or remote testing using the RTS451KEY Remote Test Station. The unit shall be reset by local reset button or RTS451KEY. The duct detector housing shall incorporate an airtight smoke chamber in compliance with UL 268A, Standard for Smoke Detectors for Duct Applications. The housing shall be capable of mounting to either rectangular or round ducts without adapter brackets. An integral filter system shall be included to reduce dust and residue effects on detector and housing, thereby reducing maintenance and servicing. Sampling tubes shall either be telescoping or be easily installed after the housing is mounted to the duct by passing through the duct housing. The enlosure shall meet all applicable NEC and NFPA standards regarding electrical junction boxes. Terminal connections shall be of the strip and clamp method suitable for 12-18 A WG wiring.
