1 INTRODUCTION
1.1 GENERAL DESCRIPTION
NOTE
ITEMS 6 THROUGH 17 DESCRIBE FEATURES OF ONE CHANNEL ONLY. THESE
FEATURES ARE NORMALLY IDENTICAL FOR ALL CHANNELS.
The AMC-1022M is a multi-sensor gas monitoring system designed to continuously monitor for traces of
hazardous gases (listed in Specifications, page v). It can be calibrated to detect a wide variety of gases, and
each channel can monitor a different gas. The monitor comes with the following features as shown in
Figures 1-2, 1-3 and 1-4:
1. POWER SWITCH -Main AC power switch for all channels.
2. FUSE HOLDER -Front panel mounted for easy access to the fuse.
3. AUDIO ALARM INDICATOR -When operational (see item 14), the buzzer will
activate when a high alarm condition occurs.
4. CLAMPS -To secure the front panel, restricting access to internal
controls.
5. POWER TERMINAL BLOCK -For line voltage connections (120 VAC, 60 Hz.).
6. POWER ON INDICATOR -Power is indicated by a green LED.
7. FAIL INDICATOR -Sensor/transmitter signal fail is indicated by an amber
LED. (Only when this option is installed).
8. HIGH ALARM INDICATOR -High levels of gas is indicated by a red LED.
9. LOW ALARM INDICATOR -Low levels of gas is indicated by a yellow LED.
10. TEST SWITCH -The test switch is provided to electronically simulate
alarms in order to test the low and high alarm
indicators, relays, and the audio alarm indicator.
11. HIGH ALARM ADJUST -Sets the High alarm trip point.
12. LOW ALARM ADJUST -Sets the Low alarm trip point.
13. SIGNAL ADJUST -Sets the sensitivity of the sensor. (Not required for
transmitter).

14. THREE CIRCUIT MINIATURE SWITCH -Each actuator on the miniature switch controls a
different circuit as shown in Figure 1-1. If the actuator
is set in the UP position, its corresponding circuit is
ON. If the actuator is set in the DOWN position, the
circuit is OFF.
LEFT ACTUATOR: Provides a TEN minute time delay, when switch is ON, to eliminate
unnecessary alarms caused by momentary exposure to high levels of
gas.
MIDDLE ACTUATOR: Provides a FIVE minute time delay, when switch is ON, to eliminate
unnecessary alarms caused by momentary exposure to low levels of
gas.
RIGHT ACTUATOR: Controls the audio alarm indicator. When ON, the buzzer will activate
when a high alarm condition occurs.
FIGURE 1.1 THREE CIRCUIT MINIATURE SWITCH
15. RELAYS -There are two DPDT relays per channel which work
with high alarm and low alarm respectively.
16. TRANSFORMER -Class II, step down transformers run the internal
circuitry at low voltages.
17. SENSOR TERMINAL BLOCK -For remote sensor or transmitter connections.
