System Sensor DH200RPL Manual

INSTALLATION AND MAINTENANCE INSTRUCTIONS Intelligent Air Duct Smoke Detector Extended Air Speed Range installing detectors please thoroughly read the NEMA Guide for Use of Smoke Detectors in Duct Applications which provides information on detector spacing placement zoning wiring special applications Copies of this manual are available from National Electrical Manufacturers Association 2101 L Street NW DC 20037 NFPA Standards 72 and 90A should also be ref for detailed information This manual shall be left with the owner user of this This detector must be tested and maintained regularly fol NFPA 72 requirements The detector should be cleaned at least a year Description HVAC system supplies conditioned air to virtually every area of building Smoke introduced into this air duct system is distrib to the entire building Smoke detectors designed for use in air systems are used to sense the presence of smoke in the duct 3825 Ohio Avenue St Charles Illinois 60174 FAX 630 377 6495 DH200RPL air duct smoke detector is photoelectric detector This detection method combines with an efficient housing design that air passing through a duct and allows detection of a developing condition When sufficient smoke is sensed an alarm signal is at the fire control panel monitoring the detector and appropriate can be taken to shut off fans blowers and change over air handling etc This can prevent the distribution or it can isolate toxic smoke fire gases throughout the areas served by the duct system LEDs on each detector may illuminate if programmed by the system panel to provide a local alarm indication There is also a remote output for use with auxiliary devices The DH200RPL has remote capability with the RTS451 RTS451KEY Remote Test Station DH200RPL incorporates a cover tamper feature When the cover is for more than 20 minutes the unit loses communication at the a trouble is indicated at the panel and the alarm relay switches thereby shutting down fans dampers and blowers In the case the sensor is removed or when there is no power to the unit only a is indicated at the panel alarm relay does not work any longer of the Duct Smoke Detector Housing Kit DH200RPL Duct Smoke Detector consists of the following items Figure 1 1 Exploded View Of Duct Smoke Detector Components HOLES TUBE TUBE BOARD Of The Duct Smoke Detector Complete duct smoke detector assembly with sensor Two 10 x 11 sheet metal mounting screws Two sampling tube filters One test magnet Drilling template Two foam gaskets Four 6 self tapping mounting screws for the sampling tube and optional exhaust tube extension One sampling tube end cap One plastic sampling tube One 8 self tapping screw for plastic sampling tube A detector sensor board DOES NOT need to ordered separately STRIP BOARD MOUNTING For ducts over 11 feet 0.46m longer sampling tubes must be ordered to complete the installation They must be the correct length for the of the duct where they will be installed See Table 1 on page 3 to determine the sampling tube required for different duct widths 1 I56 1977 004R of Duct Detectors National Fire Protection Association has established that DUCT MUST NOT BE USED AS A SUBSTITUTE FOR OPEN AREA PROTECTION as a means of providing life safety Nor are they substitute for early warning in a building regular fire detection system is strongly recommended that the user read NFPA Standards 90A 72 101 device will not operate without electrical power Fire situations cause an interruption of power The system safeguards should be with your local fire protection specialist device will not sense smoke unless the ventilation system is operat order to function properly this detector must be installed according to instructions Do not exceed the electrical or ambient specifications or detector will not function properly This detector must be protected the elements Sequence 1 Verify duct air flow direction and velocity 2 2 Drill the mounting holes 2 2.1 Install the sampling tube for

Maintenance and Test Procedures 5 Verify Duct Air Flow Direction And Velocity DH200RPL duct smoke detector is designed to be used in air han systems having air velocities of 100 to 4000 feet per minute 0.5 to Be sure to check engineering specifications to ensure that the velocity in the duct falls within these parameters If necessary use a meter to check the air velocity in the duct See Air Flow Test 9.1 paper backing Drill The Mounting Holes Affix the template to the duct at the desired mounting location sure the template lies flat and smooth on the duct Center punch A and B Drill the holes as indicated on the template mounting Sampling Tube Installation for Ducts Less Than 11 Feet Wide see Figure 2 Remove the front cover Slide the plastic sampling tube into the housing bushing Align the holes in the bushing with the holes in the sampling tube Make there are 6 exposed holes on the plastic sampling tube Secure with the self tapping screw into the bottom of the permanent tube shown in Fig ducts greater than 11 feet 0.46m in width refer to sec 4 4.1 and 4.2 Secure The Detector Housing To The Duct the foam gaskets over the tube bushings as shown in Figure 3 Use two 1 1 long sheet metal screws to screw the detector housing to duct Do not overtighten the screws Sampling Tube Installation for Ducts Greater Than 11 Feet Wide sampling tube is identified by a series of air inlet holes on the tube plastic tube is included for ducts up to 11 feet 0.46m wide All other must be purchased separately Order the correct length as speci in Table 1 for width of the duct where it will be installed It is recom that the sampling tube length extend at least 2 across the duct for optimal performance The exhaust tube is molded onto the base the duct housing and the A2440 00 Exhaust Tube Extension is available an accessory in those cases where the molded exhaust port does not at least 2 inches 50mm into the duct sampling tube is always installed with the air inlet holes facing into air flow To assist proper installation the tube mounting flange is with an arrow Make sure the sampling tube is mounted so that arrow points into the air flow see Figure 4 Figure 5 shows the combinations of tube mounting configurations with respect to air Mounting the detector housing in a vertical orientation is acceptable that a metal sampling tube is installed and the air flows directly the sampling tube holes as indicated in Figure 4 2 Plastic sampling tube to duct smoke detector Installation For Ducts Greater Than 11 Feet 0.46m But Than 8 Feet 2.4m Wide If the tube is longer than the width of the air duct drill a 3 19mm in the duct opposite the hole already cut for the sampli
