Cerberus Pyrotronics DI-4A Ionization Smoke Detector 6113

ENGINEER AND ARCHITECT SPECIFICATIONS Smoke Detector Flush or Surface Mounting Compact Adjustable Sensitivity Screw type Terminals Versatile New Flow POC Path Rugged Alarm Light Simple Twist Lock Assembly Solid State Circuitry Superior Air Velocity Characteristics Listed ULC Listed FM CSFM NYMEA and City of Chicago Approved Cerberus Pyrotronics Model DI 4A smoke detector adjustable sensitivity operates on the ionization It is designed to respond to the first traces of fire the form of visible smoke or invisible products of Heat or flame is not required to activate the The Model DI 4A detector has been developed protection of a wide range of commercial industrial and residential occupancies Description DI 4A detector is a plug in dual chamber ionization with adjustable sensitivity and contains two chambers together with a highly sensitive amplifier switching circuit One chamber the presence of combustion products The chamber serves as a reference to stabilize the sensitivity for changes in environmental tem humidity and pressure The detector assembly in upon alarm therefore it must be reset at the panel DI 4A can be manually adjusted to two different settings Low and High This is easily done by the sensitivity indicator located on the underside the detector housing with a small pointed instrument as a ball point pen detector operates from a 20 VDC source provided by Cerberus Pyrotronics control panel The detector a very small standby current less than 110mA permits the use of a 2 wire detector circuit of 18 wire reducing system installation costs In alarm detector will draw approximately 175mA with remote DI 4A detector is Underwriters Laboratories Inc listed ordinary indoor applications assemblies for either flush or surface mounting all screw type terminals are available for use with the DI detector as follows Base with Integral Alarm Lamp and Connection for Remote Relay or Alarm Lamp Base with Integral Alarm Lamp and Connection for Remote Alarm remote indicator lamp Model RL 30 or RL 40 may be when the detector is concealed from view or a relay Model RR 2 may be connected to the DI 4A a detector controlled function is required at or near detector The Model RR 2 relay has one set of double double throw contacts rated at 120 VAC 2 Amp NUMBER the RR 2 is used and the control function is critical more than one DI 4A should be installed in a particular or zone and no other initiating devices should be in that same circuit or zone An exception to this would be an application where a number of RR 2 were used each of which was connected to the critical control function Data DI 4A detector utilizes either a flush or surface mount base assembly Each base may be attached to a 4 octagonal electrical box with an adapter when conduit is used or may be used without when local building codes permit The DB 4TS base provision for an optional field installed locking to prevent unauthorized removal of the head A flush locking base Model DB 4TFL is available detector shell and base are fabricated of rugged material eliminating any corrosion prob They are off white in color and attractively styled to unobtrusive and to match most interiors using the Cerberus Pyrotronics sensitivity tester Model the detector can be easily checked for proper Data more than thirty 30 detectors of any type or combina other than thermals or manual stations may be used any one Cerberus Pyrotronics detector circuit detector is applicable to the 30 foot center spacing sq ft as referred to in the National Fire Protection Standard 72 This however is based on ideal namely smooth ceiling no air movement and physical obstructions between the fire source and the This spacing should be used as a guide or point in detector installation layout Do not mount in areas close to ventilating or air conditioning Exposed joists or beamed ceilings may also affect spacing limitations for detectors It is mandatory that judgment be applied regarding detector and spacing and Architect Specifications fire detector shall be a Cerberus Pyrotronics Model DI with adjustable sensitivity It shall operate on the principle activated by the presence of combus products and shall be listed by Underwriters Labora Inc The detector shall be a plug in twist lock unit may be installed in or removed from its base with hand detector shall contain two ionization chambers circuit and solid state indicator lamp chamber shall be for fire detection and the second shall function as a reference to stabilize the for changes in environmental temperature and pressure The unit shall contain no operat moving parts amplifier switching circuit in the detector shall be solid state and shall operate with a detector line of 20 VDC unit shall be capable of being manually adjusted for or high sensitivity The resulting sensitivity setting shall visible through an indicator slot located on the detector No special tools shall be required to change the setting base assembly into which the detector is installed be of the twist lock type with screw type terminals shall be a Cerberus Pyrotronics Model DB 4 Insert TS TF Pigtails or in line connectors shall not be permitted base shall include a lamp to indicate alarm of the is possible to connect either a remote lamp Model RL RL 40 or a remote relay Model RR 2 to the base The relay shall contain a set of DPDT contacts at 120V 60Hz 2 amp resistive for the control of devices security base lock shall be installed in those areas where resistant installation is required maintenance is required the unplugged detector shall capable of normal handling without causing damage to such as field effect transistors detector or group of detectors shall require a two wire of 18 AWG
