Data Sheet 2106 T" AsB_�u � tt Engineered Systems - - Discove PhotoelectricP Detector �. • DISC-P - - r 0_eserip-tion The AsBuilt intelligent analog addressable photoelectric detector(DISC-P) operates seamlessly with the AsBuilt IP Fire SeriesTm network fire control. The DISC-P communicates to and is managed and controlled by the IPF SeriesTm analog loop module(ALM). The Disc-P is physically distinguished from the Discovery ionization IF.eatures detector(DISC-])by the clear colored dual LED's.The LED's light steady when in an alarm condition and flash briefly when polled by the ALM.The Improved detection capabilities with dual LED's provide for 360 degree visibility. smoldering,smoky fires • Discovery detectors distribute O eration intelligence across the installed system The DISC-P constantly monitors its sensing chamber and its internal e Patented infrared smoke sensing electronics utilizing a patented smoke chamber and infrared smoke design sensing design. . Sleek,non-fading white polycarboriate An infrared light emitting diode with its collimator is arranged at an obtuse enclosureZero insertion force base angle to the photo-diode.The photo-diode has an integral daylight blocking filter.The IR LED emits a burst of collimated light every second. i 5 user selectable modes In clear air the photo-diode receives no light directly from the IR LED 0 Powerful transient rejection algorithms because of the angular arrangement and the chamber baffles.When 0 Conventional device mode smoke enters the chamber it scatters light from the emitter IR LED onto . Patented XPertprogramming card the photo-diode in an amount-related to the smoke characteristics and eliminates addressing errors during density.The photo-diode signal is processed to provide an analog value for transmission when the detector is interrogated by the ALM. system installation and maintenance • Alarm flag sends signal to system Upon crossing the alarm threshold the detector will make the even when device is not being determination that an alarm condition exists and send a signal to the ALM interrogated that interrupts the normal polling process to signal the alarm condition. 9 Wide variety of addressable The ALM puts the changed state on the IP network and all outputs input/output devices associated with the specific detector are activated. 0 Relay and synchronized temporal sounderbases The DISC-P manages its own automatic drift compensation thereby 0 Green/RoHS Compliant accelerating overall system performance by offloading the management of the device compensation values from the ALM to the DISC-P. Compensation is made to adjust the detector for the infiltration and Listings accumulation of dirt and dust over time.By compensating the detector alarm thresholds the sensing window is adjusted to remain at original UL File: S5022 factory specifications. CSFM:7272-1394:118 MEA:294-95-E-4 Like all Discovery devices,the DISC-P has five pre-programmed user settings that may be accessed and changed from the IPF Series network control.Further,the pre-programmed settings are utilized in establishing the automatic sensitivity values in place with the IPF Day/Night sensitivity programming.
