d800-02-00 1 i56-2026-02r ed-p, ED-PT, and ed-dp intelligent photoelectric smoke detectors installation and maintenance instructions 3825 ohio avenue, st. charles, illinois 60174 1-800-sensor2, fax: 630-377-6495 www.systemsensor.com before installing this detector must be installed in compliance with the con - trol panel system installation manual. the installation must meet the requirements of the authority having jurisdiction (ahj). detectors offer maximum performance when installed in compliance with the national fire protection association (nfpa); see nfpa 72. general description models ed-p, ED-PT and ed-dp are intelligent photoelec - tric, spot-type smoke detectors utilizing sensing chambers that are designed to respond rapidly to a broad range of fires. the sensing chamber employs features that minimize the effects of settled dust on performance. model ED-PT uses a thermistor based, 135f heat detection circuit in addition to the photoelectric sensing chamber. ed-dp is designed for use inside the ed-dpr duct housing only. ed- dp should not be used in open area applications. the detector is designed with tri-color leds to indicate detector status. the detector can be programmed to make the leds blink or be steady green, amber or red. the detec - tor remote output can be configured to follow the led or be independently controlled. a remote led annunciator is available as an accessory (ra400z). the ed-p, ED-PT and ed-dp require compatible address - able communications to function properly. connect these detectors to listed-compatible control panels only. spacing system sensor recommends spacing detectors in compli - ance with nfpa 72. in low air flow applications with smooth ceilings, the detectors should be spaced 30 feet specifications normal operating voltage: 15 to 30 vdc standby current: 481a max. @ 24 vdc (continuous broadcasts) alarm current: 2 ma max. @ 24 vdc (leds on) humidity range: 10% to 93% relative humidity, noncondensing temperature range: 32f to 120f (0c to 49c ); ed-p, ed-dp 32f to 100f (0c to 38c); ED-PT heat detector: 135f fixed temperature electronic thermistor height: 2.1 inches (51 mm) installed in ebf base diameter: 6.1 inches (155 mm) installed in ebf base 4.1 inches (104 mm) installed in eb base weight: 5.2 oz. (147 g) apart. for specific information regarding detector spacing, placement, and special applications, refer to nfpa 72 or the system smoke detector applications guide, available from system sensor. duct applications: ed-p and ED-PT are listed for use in ducts. see duct applications guide a05-1004-xx for details on pendant mount applications. wiring guide all wiring must be installed in compliance with the national electrical code, applicable local codes, and any special requirements of the authority having jurisdiction (ahj). proper wire gauges should be used. the installation wires should be color-coded to limit wiring mistakes and simplify system troubleshooting. improper connections will prevent a system from responding properly in the event of a fire. 1. wire the detector base (supplied separately) per the wir - ing diagram, see figure 1. 2. install the detector into the base. push the detector into the base while turning it clockwise to secure it in place. 3. set the desired address using the ir configuration tool (model no. eaCct). note: maximum range for the eaCct is 30 ft. (9 m). 4. test the detector(s) as described in the testing section of this manual.
d800-02-00 2 i56-2026-02r caution dust covers provide limited protection against airborne dust particles during shipping. dust covers must be removed before the detectors can sense smoke. remove detectors prior to heavy remodeling or construction. tamper-resistance models ed-p and ED-PT include a tamper-resistant capabil - ity that prevents their removal from the base without the use of a tool. refer to the base manual for details on mak - ing use of this capability. testing before testing, notify the proper authorities that the system is undergoing maintenance, and will temporarily be out of service. disable the system to prevent unwanted alarms. all detectors must be tested after installation and periodi - cally thereafter. testing methods must satisfy the authority having jurisdiction (ahj). detectors offer maximum per - formance when tested and maintained in compliance with nfpa 72. the detector can be tested in the following ways: a. functional: this detector can be functionally tested by using the eaCct. following the instructions, initiate the detector test sequence. the detector will then send a test alarm message to the panel. refer to the control panel techni - cal documentation for further information. c0113-00 + ? ? + listed compatible control panel optional return loop optional remote annunciator + ? 1 2 3 4 1 2 3 4 b. smoke entry: smoke entry testing should be performed immediately following the functional test. the functional test initiates an approximately 5 minute period when the detectors signal processing software routines are not active. failure to do so will introduce a time delay before the detector alarms. home safeguard model 25s smoke detector tester can be used to verify smoke entry into the sensing chamber and the corresponding alarm response. aim the aerosol can at the detector and spray for one to two seconds from a distance of two to four feet until the panel alarms. another method is to use the gemini model 501 aerosol generator for smoke entry testing. set the generator to represent 4%/ft. to 5%/ft. obscuration as described in the gemini 501 manual. using the bowl shaped applica - tor, apply aerosol until the panel alarms. c. direct heat (ED-PT only): a hair dryer, heat gun, or test apparatus designed for this purpose should be used to test the thermistors. direct the heat toward either of the two thermistors, using care to avoid damaging the plastic housing. the detector will reset only after it has had sufficient time to cool. make sure that both thermistors are tested individually. a detector that fails any of these tests should be cleaned as described under cleaning, and retested. if the detector fails after cleaning, it must be replaced. when testing is complete, restore the system to nor - mal operation and notify the proper authorities that the system is back in operation. figure 1. wiring diagram: caution: do not loop wire under terminal 1 or 3. break wire run to provide supervision of connections.
