30 3003 Smoke Detector Pyrotector Model 30 3003 Explosion Proof Smoke Detec is a sensitive yet rugged protection device that is designed use in hazardous industrial and commercial locations The is designed to operate effectively with both slow smol and fast burning fires Rugged construction Self checking and compensating circuitry maintains desired Heightened sensitivity triggered when smoke is increasing has not yet reached the preset sensitivity setting Form A SPST N O contacts for connection to alarm out circuitry SPST N C contacts for supervision of input power 2.3 fixed sensitivity Combustible storage facilities Munitions manufacturing Volatile chemical storage Chemical processing plants Petroleum refineries Turbine enclosures Operation photoelectric smoke detector uses a solid state infrared diode IRED and a light sensing photovoltaic cell in a labyrinth assembly The labyrinth permits free to smoke but restricts external light Because of its function to the operation of the detector each IRED is with extreme care and is subjected to rigorous pre testing to ensure long term reliability and perfor normal operation no smoke the detector samples the approximately every four seconds for a period of less than millisecond The photovoltaic smoke cell which is placed an angle to the pulsed invisible light source is sensitive to infrared light in the specified frequency emitted by the light source and is designed to receive a signal only the pulsed IRED source is activated See Sec of Sensing Chamber Assembly at top of opposite column smoke enters the chamber the light from the IRED off the smoke particles and reaches the photovoltaic cell When the amount of light reflected by smoke the factory set threshold level the smoke alarm circuit actuated detector will respond to a slow smoldering fire when in the chamber reaches the preset sensitivity setting 2.3 a fast burning fire should occur including fires in flammable and other materials such as plastics that generate black the abnormally rapid movement of smoke into the chamber is sensed by a special rate compensating Initiating Devices Section of Sensing Chamber Assembly An increase in smoke within the detection chamber exceeds a preset rate causes the rate compensation cir to increase the intensity of the light source which detector sensitivity If the smoke continues to build this rate an amplifier circuit is triggered and the unit gener an alarm If not the detector reverts to normal sensitivity normally smoky atmospheres the detector will not go into as long as the concentration is less than the fixed sensi of the detector This results in a sensitive and positive with a very low potential for unwanted alarms main enclosure of the detector contains the electronic cir alarm relay and supervision relay Operation To ensure reliable operation the Model is equipped with self checking circuitry A regulation which is matched to the smoke detection circuit monitors the output intensity of the IRED and it as necessary to compensate for an accumulation of or other contaminants or any other variation that can with temperature and time A power supervision relay in detector provides a trouble output signal in the event of an power failure detector uses extensive filtering against RF and transient In addition there is a two second time delay an alarm is generated printed circuit board inside the detector is coated to mini the possibility of problems caused by moisture accumula Outputs The detector provides a set of Form A N O contacts for connection to the alarm output cir and a set of SPST N C contacts for supervision of input An auxilliary set of Form C SPDT NO NC alarm relay is also provided for controlling remote annunication 03 21 2012 Page 1 of 2 Specifications detector shall be a 2.3 fixed sensitivity photoelectric detector providing minimum response time to all fire detection chamber shall extend beyond the main housing the area to be protected to provide maximum smoke entry into the chamber from any direction detector light source shall be an IRED Infrared Emitting Typical detector current consumption in the standby shall be 10 milliamperes detector shall lock in on alarm and have a visible alarm LED detector shall have SPST alarm relay contacts for connec to the fire alarm control panel and also power supervision detector enclosure shall be an explosion proof flanged designed to meet CSA certification for use in Class 1 2 Groups A B C and D hazardous locations detector shall be intended for surface mounting and con to the system wiring shall be within a rated enclosure Line Information Explosion Proof Smoke Detector The alarm output latches on in the event of an alarm an LED located on the outer surface of the housing is illu to provide a visual indication that an alarm condition occurred The detector is reset by momentarily interrupt input power The Model 30 3003 is designed to meet NEC for Class I Division 2 Groups A B C and D areas CSA certified for use in Class 1 Division 2 A B C and D hazardous locations Certification The Model 30 3003 is certi by the German Electric Industry Association VDE to Standards 0171 Protection Ex sG5 sand and PTB CENELEC approved as EEx q II T5 Voltage 20 to 28 volts DC Current Standby 10 milliamperes Alarm 35 Range to 140 to 60 and Supervisory Relay Contact Rating 1.0 ampere 30
