DB-M01 Detector Base

DB-M01 Detector Base is designed for a new generation of D-series detectors. It is suitable for both conventional and intelligent D-series detectors, including UL-certified models DI/DC-M9101, DI/DC-M9102, and DI/DC-M9103 produced by GST.

Installation Steps

1. Locate the mounting holes on the rubber seal of the base according to the holes
   on the electrical junction box, then punch the holes using a screwdriver.
2. Determine the number of cables required and punch the appropriate number of holes
   on the rubber seal at the cable entry position. Thread the cables through the holes.
3. Install the base onto the junction box using screws.

Warning: Do not punch mounting or cable entry holes larger than necessary or more than required.

Wiring Connection

1) Connecting with Intelligent Detectors

• Terminals “1” and “3”: Connected to the loop of the control panel (non-polarized)
• Terminal “2”: Connected to the anode of the remote indicator
• Terminal “4”: Connected to the cathode of the remote indicator

2) Connecting with Conventional Detectors

• Terminal “1”: Connected to output anode of I-M9300 module
• Terminal “2”: Output to next detector (Terminal 1) and connected to anode of remote indicator
• Terminal “3”: Connected to output cathode of I-M9300 module and cathode of next detector
• Terminal “4”: Connected to cathode of remote indicator

A 4.7k/1W end-of-line resistor must be connected between terminals “2” and “3”
of the last base in the loop.

Installation Notes

Installation and maintenance must comply with NFPA 72 requirements. Fix the base using two tapping screws. Align mark A on the detector with mark B on the base, then rotate until mark A aligns with mark C. The detector will then be secured to the base.
