H V A C S Y S T E M S M O N I T O R I N G Series Intelligent Duct Smoke Detectors Intelligent Model Available ED-DPR: Duct Housing ED-DP(I): Duct Sensor Head *I denotes isolator version Product Overview Air velocity rating from 500 to 4000 feet per minute (2.54 to 20.32 m/sec.) Operates from the control panel communication line Continuous sensitivity monitoring from the panel Intelligent photo isolator or non-isolator heads with twist-in/twist-out removal Easy to clean UL recognized field-replaceable power boards Transparent cover for convenient visual inspection UL 268A listed 3-year warranty Has outputs for remote LED display, remote test Requires com line power only Powered outputs for remote LED, and remote test and sounder Remote test station and remote annunciator accessories APPROVED S911 The System Sensor Eclipse™ Series photoelectric air duct smoke detectors are capable of sensing smoke in air velocities from 500 to 4,000 feet per minute (2.54 to 20.32 m/sec). The Eclipse Series ED-DPR duct housing can accommodate either the ED-DP or ED-DPI Intelligent Photoelectric Sensor. The twist-in, twist-out heads allow for quick and easy cleaning or application changes without removing the duct housing. The Eclipse Series Detector samples air currents passing through a duct and gives dependable performance for shutdown of fans, blowers, and air conditioning systems, preventing the spread of toxic smoke and fire gases through the protected area. These intelligent sensors communicate and are continuously monitored through the communication line. Detector sensitivity changes caused by dirt, temperature, or humidity are reported to the panel, allowing compensation algorithms to maintain the sensor’s set sensitivity. An advance indication at the panel specifies the sensor address, allowing for selected maintenance to be performed as needed. Remote alarm annunciation can be accomplished by using the RA400Z Remote Annunciator or the RTS451 or RTS451KEY Remote Test Station. Both these devices allow testing of the detector from a remote location. The Eclipse Series is designed for simplified installation and easy maintenance. WARNING: Duct smoke detectors have specific limitations. DUCT SMOKE 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 smoke detector application information. Architect/Engineer Specifications The duct smoke detector shall be a System Sensor Model ED-DPR Intelligent Duct Smoke Detector to be used with compatible control panels. The duct smoke detector shall be UL listed per UL 268A, Standard for Smoke Detectors for Duct Applications, specifically for use in air handling systems. The detector shall operate in air velocities from 500 to 4000 feet per minute. The detector housing shall be equipped with an integral mounting base capable of accommodating either the EDDP or ED-DPI photoelectric detector head. It shall be capable of remote testing from the RTS451 or RTS451KEY Remote Test Station. The duct smoke detector housing shall incorporate an airtight smoke chamber in compliance with UL 268A. 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, thereby reducing maintenance and servicing. Sampling tubes shall be easily installed after the housing is mounted to the duct by passing through the duct housing. Terminal connections shall be of the strip and clamp method suitable for 14-18 AWG wiring.
