Description

Product Overview

OT602 Smoke Detector is designed in transnormal thin style. With a unique optical sensing chamber designed to sense smoke particles produced by a wide range of combustion sources. The sensing chamber is sealed against back pressure air flow, dirt, and insects. This chamber is protected by a fine mesh screen which can be cleaned or replaced. Its hardware filter can verify the true fire and reduce false alarm.

 

Characteristics

  • Transnormal thin design for thickness , just 45mm.
  • Adopt SMT technology, firmly, high secure and antijamming.
  • Special methods for damp-proof, antisepsis and mildew-proof.
  • With inner mothproof net and shield cover
  • Flame retardant thermoplastic
  • Easy plug-in of the head to base
  • SEMS screws for easy wiring
  • 2-wire without polarity
  • Comply with Standard: GB4715-2005

Configuration and Installation Guide

  1. The Model of OT602 base is ODZ6004. Model 86H50 wall mounting enclosure or other
    enclosure with 40~85mm mounting hole space should be used.
  2. The side of detector bottom and the side of base has one convex edge each. There is one
    slot on the base. When mounting, make the convex edge pointing to the slot in the base,
    and then place the detector into the slot. Finally turn clockwise until the convex edge of
    the unit is flush with the convex edge of base.

 

Wiring

1 and 2 terminals are connected to the corresponding signal input terminals (without
polarity) of fire alarm control panel or interface modules respectively. One EOL (End of Line)
resistor should be connected in series between 1 and 3 terminals of the detector at the end
of line. The specs of the resistor should refer to the requirement of control panel or
interface module.

 

Notice

  1. After installing, the detector has to be locked into the slots of base, and its convex edge
    should be flush with the convex edge of base. Otherwise, it will be reinstalled.
  2. After installed onto the base, wire pipe on the ceiling should be sealed with sealing paste
    or sealing glue to prevent accumulated water going into the unit.
  3. When connecting, the wire should be with cooled terminals or tinned, and can’t be
    wound randomly.
