GST DB-M01N Manual

Description
DB-M01N Detector Base is designed for a new
generation D-series detector. It is suitable for both
conventional and intelligent
including UL-certified DI/DC-M9101N, DI/DC-M9102N,
DI/DC-M9103 produced by GST.
Connection and Cabling
DB-M01N base is shown in Fig. 2.
Fig. 1
Please install the base with the following steps:
1) Locate the mounting holes on the rubber seal of
the base according to the holes on the electrical
junction box, and punch the holes with a
screwdriver.
2) Count the number of cables needed and punch
correct number of holes with a screwdriver on the
rubber seal at the cable entry position. Thread
the cables through the cable entry holes.
3) Install the base onto the junction box with
screws.
Warning: Do not punch mounting holes and cable
entry holes bigger than needed. Do not punch
more holes than needed.
There are four terminals with number on the base. The
following describes the specific connection.
1）Connecting with Intelligent Detectors
"1", "3" are connected with loop of the control panel,
insensitive-polarity; "2" is connected with anode of
remote indicator and "4" with cathode of remote
indicator. Please refer to Fig 3 for system connection.

2） Connecting with Conventional Detectors
"1" is connected with output anode of I-M9300 module;
Fig. 2
"2" is used as output, connected with anode of next
detector (Terminal 1) and also connected with anode of
remote indicator; "3" is connected with output cathode
of I-M9300 module and the cathode of next detector
(terminal 3); "4" is connected with the cathode of
remote indicator.
Between terminals "2" and "3" of the last base in the
loop, there should be connected with a 4.7k/1w
end-of-line resistor. Refer to Fig.4 for system
connection.
Installation
Installation and maintenance of the base should
comply with the requirements of NFPA 72.
Fix the base with two tapping screws, and then align
mark A on the detector with B on the base, rotate the
detector to align mark A with mark C (Refer to Fig. 1
Remote Indicator
and 2 for the position of the marks), the detector will
