Cerberus Pyrotronics DF-30 Ultraviolet Flame Detector 6129

Ultraviolet Flame Detector AND ARCHITECT SPECIFICATIONS DF 30 DF 30 Simple Twist Lock Assembly Alarm LED Two Wire Operation Cerberus Pyrotronics Model DF 30 Flame Detector directly to the presence of flame It senses ultra radiation emanating from flames which must be for at least 5 seconds flame detector is intended to protect hazards where anticipated fire will develop quickly with little or no or smoldering stages where ignition is almost e g flammable liquids combustible gases etc detector utilizes an ultraviolet sensitive cold cathode which operates on the Geiger Mueller Principle gas filled detection tube consists of an anode and a which is sensitive to ultraviolet wavelength of Angstroms Both electrodes are energized by voltage When ultraviolet rays reach the cathode pho are emitted toward the anode by forcing the gas to emit electrons As the number of ionized begin to increase an electrical current will flow the electrodes As ultraviolet rays continue to the detection tube a pulsed electrical signal is gen which is digitally Upon completion of the delay cycle if the electrical signal is still present detector locks into an alarm condition and can only be at the control panel by an interruption of power detector utilizes a low profile surface mounting base DB 3S which may be attached to either a 4 octa 4 square wiring box or single gang outlet box The base utilizes screw clamp terminals for all electrical self wiping contacts for reliability and con provisions for an optional concealed locking mecha to prevent unauthorized removal of the detector unit is capable of operating a remote alarm lamp RLI RL30 RL40 or auxiliary relay Model RR 3 The Model relay contains one set of double pole double throw rated at 120 VAC 2 amps resistive and requires a electrical box when mounted to the DB 3S NUMBER Data detectors are essentially line of sight devices there special care must be taken in applying them to insure their ability to respond to fire in the area which is to be will not be compromised by the presence of structures or other opaque objects or materials detectors should be installed at a point which provides most direct line of fight with the anticipated source of connected to Cerberus Pyrotronics control equip the DF 30 is fully compatible with other types of Pyrotronics detectors No more than five 5 detectors may be used on any one Cerberus detector circuit and Architect Specifications Flame detector shall operate on the ultraviolet radia principle The amplifier switching circuit in the detec shall be entirely sold state contain no moving parts and an alarm actuation delay of 5 seconds base assembly into which the detector is installed be of the twist lock design with screw clamp termi The base shall utilize self wiping contacts for reliabil and shall be directly interchangeable with other compat plug in detectors A security lock DB LK shall be in those areas where tamper resistant installation required as indicated on the drawings Auxiliary relays remote alarm lamps shall be installed where detector or group of detectors shall require a two wire of 18 AWG thermoplastic fixture wire enclosed in or 18 AWG limited energy shielded cable without if permitted by local codes detector assembly shall be a Cerberus Pyrotronics DF 30 Specifications Requirements Normal 500mA Max Typical 3 VDC 10 to 122 50 Range Range of Vision Information Lock for DB 4TS Weight Flame Detector with 5 delay Profile Mounting Base Relay DPDT Alarm Lamp Alarm Lamp Alarm Lamp 45 45 45 45 45 45 45 Wiring The use of other than Cerberus Pyrotronics detectors and bases with Cerberus Pyrotronics will be considered a misapplication of Cerberus Pyrotronics equipment and as such void all either expressed or implied with regard to loss damage liabilities and or service problems Pyrotronics Ridgedale Avenue Knolls NJ 07927 201 267 1300 201 397 7008 in U S A Pyrotronics East Pearce Street Hill Ontario 1B7 CN 905 764 8384 905 731 9182 1995 sheet dated 8 94
