Hochiki smoke detector wiring diagram. The result is a high performance optical chamber that is equally responsive to all smoke types and helps to reduce the possibility of unwanted alarms. Interconnect wiring diagrams air duct smoke detectors shall be hochiki america dh 98 series. The black and white wires provide the smoke detectors with the power needed to sound an alarm when smoke is detected. For example the firenet control panel. 72 section on inspection testing and maintenance. Hochiki slr e is conventional intrinsically safe photoelectric smoke detector.
When installing the detector check that the location of each one has. Firenet 4127 i o manual firenet 21274127 analog addressable fire alarm system installation and operation manual hochiki america corporation. The detector dfjrange and dcdrange are used to detect conditions and changes in temperature and cannot detect smoke and other phenomena. To install the detector insert the detector into the base. For a single smoke detector used in single level homes or apartments the yellow wire on the smoke detector can be set aside. Connect wiring to the bases as shown in the wiring diagrams that follow.
Detectors and bases may be mixed on the same initiating loop as long as the number of two wire powered detectors does not exceed the specifications of the control panel see figure 2 below smoke detector data built in test feature 135fslr 24h only 30zone 177 300 vdc hd3 fig. Hochiki detectors cannot be used to prevent fire itself they are only intended to detect a certain characteristic of fire. 55ma alarm 3 4 5 dh 98 ar dh 99 ar wiring diagram dh 98 adh 99 a wiring diagram the dh 98 adh 99 a and dh 98 ardh 99 ar are not self contained sensors. Hochiki has taken its mission to eliminate unwanted alarms to a whole new level by redesigning the chamber structure within its photoelectric smoke detector range. This product is compatible only with fire alarm control panels that utilize hochikis digital communications protocol dcp. The detectors shall operate at air velocities from 300 feet per minute to 4000 feet per minute.
Smoke detectors should be tested upon completion of installation and at least semiannually thereafter in accordance with nfpa. Turn the detector clockwise until it stops. Once a smoke detectors wires are properly connected to the wiring on the wall or the ceiling screw it tightly on the wall or the ceiling. The hochiki aln v photoelectric smoke sensor is particularly suited to detecting optically dense smoke typical of fires involving materials such as soft furnishings plastic foam or other similar materials which tend to smolder and produce large visible smoke particles. The detectors shall have the ability to interconnect up to 30 units using the same. Every other smoke detector is connected to the others through the yellow wire.
Hochikis unique design allows.
