DI 3 DI A3 and DI B3 Smoke Detector AND ARCHITECT SPECIFICATIONS Adjustable Sensitivity Dual Chamber Sensitivity Test Points Simple Twist Lock Assembly Optional Auxiliary Relay Screw Clamp Terminals Alarm LED ULC Listed NYMEA CSFM Approved Cerberus Pyrotronics DI 3 DI A3 and DI B3 fire smoke operate on the ionization principle The detectors to the first traces of fire in the form of visible or invisible products of combustion The DI 3 DI and DI B3 have been developed for the wide range of industrial and institutional fire detection and applications The DI 3 DI A3 and DI B3 are in environments covered by UL 268 UL 268A DI B3 must be utilized with a Series 3TM air duct DI 3 Series detector is a plug in ionization detector is designed for two wire system operation The DI 3 is with adjustable sensitivity while the DI A3 and DI B3 have a fixed sensitivity designed for their indi high air flow applications DI 3 DI A3 and DI B3 consist of self compensating ionization chambers and a highly stable solid state circuit One chamber detects the of combustion products the second chamber as a reference to stabilize the detector sensitivity changes in environmental conditions As products of enter the sampling chamber the chamber is reduced producing a voltage change At the time voltage range exceeds the pre determined threshold alarm is signaled to the control unit The detector locks upon alarm and must be reset from the control panel sensitivity of the DI 3 DI A3 and DI B3 is preset at the The electrical sensitivity can be monitored in the using the Cerberus Pyrotronics sensitivity tester test TM I3 The sensitivity test jack on the DI 3 DI A3 DI B3 and the adjustment screw on the DI 3 are from the front of the detector housing enabling user to perform all sensitivity adjustments and tests removing the detector from its base detectors utilize a low profile surface mounting base DB 3S which may be attached to either a 4 single gang outlet box or 4 square wiring box or the audible base model ADB 3 which must be to a 4 square deep wiring box The DB 3S base ADB 3 audible base utilize screw clamp terminals for electrical connections self wiping contacts for reliability contain provision for an optional concealed locking to prevent unauthorized removal of the head DI 3 Series ionization detector has been designed to a wide range of system design parameters The DI 3 is designed for open area protection in areas with velocities up to 300 feet per minute NUMBER Data is recommended for use in high air velocity applica such as computer room underfloor areas The model contains a specially designed internal chamber and a pre selected fixed sensitivity setting which extremely stable operation Model DI A3 has UL listed for operation in air velocities of 0 to 1200 per minute Since air velocity has an effect on detector and performance the DI A3 should be used only applications which meet this established air velocity DI B3 is designed specifically for use with the Pyrotronics Series 3 air duct housings and like DI A3 contains a specially designed internal chamber and a pre selected fixed sensitivity setting The DI must be utilized with the Series 3 air duct housing in air applications with air velocities of 400 4000 FPM DI 3 DI A3 and DI B3 are also available for high applications 3000 to 8000 feet above sea level model numbers DI 3H DI A3H and DI B3H DI 3 and DI A3 are capable of operating a remote lamp RLI1 RLI2 RL 30 RL 40 or auxiliary relay RR 3 The model RR 3 3S relay contains one set of pole double throw contacts rated at 120 VAC 2 Resistive and requires a deep outlet box when to the DB 3S The DI B3 is capable of utilizing the relay as supplied in the Series 3 air duct housing AD 3 with a DA 3SR Relay Board which contains set of double pole double throw contacts rated at 125 VDC 3 Amp Resistive multiple detector relay combinations are used on the circuit the zone module current limit will restrict the of guaranteed detector relay actuations to one per DI 3 DI A3 DI B3 DI 3H DI A3H and DI B3H detectors are Underwriters Laboratories Inc The series is also FM CSFM and NYMEA ap FM approved intrinsically safe DI 3 is available under DI 3IS The DI 3IS must be utilized with the intrinsi safe System 3 zone module model ZS 30 or MXL module CZM 1 Data DI 3 DI A3 DI B3 DI 3H DI A3H and DI B3H detec are fully compatible with other Cerberus Pyrotronics 3 compatible detectors and may be intermixed on same zone circuit No more than thirty 30 detectors of type of combination other than thermals or manual may be used on any one Cerberus Pyrotronics circuit detector is applicable to the 30 foot center spacing sq ft as referred to in NFPA 72 This spacing is based on ideal conditions namely smooth no air movement and no physical obstructions the fire source and the detector This spacing be used as a guide or starting point in the detector layout Do not mount detectors in areas close ventilating or air conditioning outlets Exposed joists or ceilings may also affect safe spacing limitations detectors It is mandatory that engineering judgment be regarding detector location and spacing and Architect
