3. Characteristics
■ It has a microprocessor
■ Selectable the kinds of Detector by Jumper Pin (combustible gas sensor and toxic transmitter)
■ It is easy to operate because it has three color LED bar graph
■ Normal: Green / 1st Alarm: Yellow / 2nd Alarm: Red (51 segments)
■ Self diagnostics functions
■ Linear DC 4 to 20 mA output retransmission
■ Easy alarm set point Adjustment
■ Two alarm levels (High alarm, High-High alarm)
■ Adjust Internal Settings without Power Off
■ Plug-in Modularity
■ Short Circuit Protection, 0.5A Glass Fuse Protection
■ Sensor trouble alarm
■ High density construction is possible by using of adoption of 36×144 mm front DIN standard
■ You can select between multi case and single case
■ Long sensor lifetime
■ GM-1000 is a digital gas leakage indicator with microprocessor application circuit.
■ It is upgraded product compare with before product (easiness of reading indication value and alarm
state, confidence, easiness of using)
■ GM-1000 is installed at the place using gases by raw materials, supplying gases or the place can be
leak gas, like industrial areas, gas charging sites, petrochemical plants, chemical plants, etc. And it can
protect industrial calamity by detecting gas leakage and notifying in advance. Then it can be applied to
detector of combustible gases (methane, ethane, LPG, LNG, etc.) and toxic gases.
■ 4.It may be used with common alarm unit (AM-2000) Specifications

6.5 The select of sensor and signal source
6.5.1 local detector (diffusion type combustible detector)
1) You may release the lock screw of detector and pull out an instrument from the case carefully.
2) After you off the power, you may connect the connector between a detector and a terminal.
3) You may select the input select jumper on a back lower of connector to the connecting point
of combustible gas sensor (refer to Fig. 4.4)
4) You may recombine connector between instrument and terminal
Notice 1) You may not connect wrong position of connector when you recombine.
2) Do not combine indicator to connector of common alarm unit.
(You may put a common alarm unit on the very left side of instrument array due to
distinguish the position of alarm unit)

5) You may connect a sensor to the terminal of instrument (in case of Non-transmitter type)
⊙ sensor operation power + (red)
: connect to terminal #3
⊙ sensor operation power – (black)
: connect to terminal #4
⊙ sensor signal + (white)
: connect to terminal #5
⊙ sensor signal – (green)
: connect to terminal #6
6) When you extend a lead wire of sensor, you may use the wire with color or put the right tag in
order not to confuse a wire.
The permitted maximum length of line from a sensor to a detector depends on cross section
