Hochiki smoke detector wiring diagram. Hochiki slr e is conventional intrinsically safe photoelectric smoke detector. The detector dfjrange and dcdrange are used to detect conditions and changes in temperature and cannot detect smoke and other phenomena. Model slr e is is a photoelectric smoke detector designed for use in hazardous areas which also incorporates a remote indicator output and a removable chamber for easy maintenance. Connect wiring to the bases as shown in the wiring diagrams that follow. 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. The detectors shall have the ability to interconnect up to 30 units using the same.
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. 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. 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 black and white wires provide the smoke detectors with the power needed to sound an alarm when smoke is detected. 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.
Hochikis unique design allows. For a single smoke detector used in single level homes or apartments the yellow wire on the smoke detector can be set aside. Every other smoke detector is connected to the others through the yellow wire. Hochiki detectors cannot be used to prevent fire itself they are only intended to detect a certain characteristic of fire. For example the firenet control panel. 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.
This product is compatible only with fire alarm control panels that utilize hochikis digital communications protocol dcp. Interconnect wiring diagrams air duct smoke detectors shall be hochiki america dh 98 series. The detectors shall be listed by underwriters laboratories per ul 268a. 72 section on inspection testing and maintenance.
