Main Panel
The main panel is a wall mounted touch screen monitor in a general purpose (non-hazardous)
location that is accessible for set-up and observation of the display and alarms.
There are 3 models available to order:
1. 4200-IG-2: This system has up to 2 zones to configure.
2. 4200-IG-6: This system has up to 4 zones to configure. If more then 4 sensors are ordered
then several sensors can be grouped into one zone.
3. 4200-IG-10: This system has up to 4 zones to configure. If more then 4 sensors are ordered
then several sensors can be grouped into one zone
For example: Zone 1 can be set for Sensors 1-4 while Zone 2 can be set for Sensors 5-6.
A low alarm relay for each zone is activated at a low setpoint and is indicated by the touch screen
flashing yellow by pressing the zone icon. The screen text also shows the sensor number, gas
concentration and “LO” indication. The relay resets automatically when the concentration clears
below the determined differential setpoint.
A high alarm relay for each zone is activated at a high setpoint and is indicated by the touch screen
flashing red by pressing the zone icon. The screen text also shows the sensor number, gas
concentration and “Hi” indication. The relay resets automatically when the concentration clears below
the determined differential setpoint.
A high/high alarm relay common to all zones is activated at a high/high setpoint and is indicated by
the screen text “Hi/Hi”. An optional beacon and/or buzzer is also available to activate at this setpoint.
The high/high alarm maybe latched to be acknowledged and reset after the gas concentration clears.
If user is not using zone 4 Hi alarm then this relay can be selected as a common Fault alarm.
If latched, the buzzer can be silenced during an alarm condition but the beacon will only turn off when
a gas alarm has cleared and has been acknowledged.
Pressing each zone icon (e.g. Zone 1) will allow user to view which sensor was in alarm in that
particular zone as well as type of sensor (e.g. CO) and concentration.
The main panel screen provides additional user interface menus for diagnostics, set-up and general
Help information. Menus can be accessed for viewing but a password entry is required to make any
changes.
Remote Panel
Remote panels are available to mimic the screen and audio/visual alarms of the main panel. Access
to the touch screen menus are password protected on the remote panels. The main panel will accept
up to 6 remote panels depending on the model ordered.
Remote Sensor
The panel will accept one or more sensor inputs depending on the model ordered. Typical inputs are
4-20 mA signals proportional to the gas concentration.
Refer to your sensor transmitter manual for details. Routine testing and calibration is recommended
to ensure the sensor is responsive and accurate.

2.0 INSTALLATION
NOTE: If any damage to the instrument is found, please notify an Arjay Engineering
representative as soon as possible prior to installation.
2.1 Main and Remote Panel Installation
Choose a mounting location in accordance with good instrument practice. Extremes of ambient
temperature and vibration should be avoided (see specifications and installation drawing).
Remote panels can be mounted up to 300 meters away from the main panel. Sensors can be
mounted up to 4500 feet (using 14AWG wire) away from the main panel.
Important Note: The controller is set in Failsafe mode (Factory Default). This means that the
relays are in an energized state during normal operation. The N.O. relay contact will be held closed
and the N.C. relay contact will be held open during a normal condition. This will allow the relay to
return to it’s non-energized (shelf) state during an alarm, fault or power failure condition. Wire
accordingly.
2.2 Sensor Installation
Refer to sensor manual for more specification on location and wire type.
The sensor is to be mounted near the targeted gas source and protected from extremes of
temperature and damage. Keep the sensor accessible for routine calibration. Do not block with
equipment or store materials or containers in front of the sensor.
Gases may have densities greater than or less than air. Sensors should be mounted accordingly.
Sensors targeting heavier than air gases should be mounted so the bottom of the sensor housing is
approximately 250mm to 450mm (10” to18”) above floor grade to protect it from damage from
cleaning equipment and minor washdown. The sensor should be mounted above any risk of flooding.
Sensors targeting lighter than air gases should be mounted near the ceiling in a location that will be
accessible for routine testing.
Sensor location is application specific and may need to be in accordance with local regulations or
engineered recommendations.

4.2 Relay Setup
Figure 7 – Alarm Setup Screen View
The Password “2000” will be required to make changes in this section.
There are three alarm settings: Low alarm, High Alarm and Common High/High alarm
The low alarm is typically used as a warning level that gas is present but at a safe level. It is not
unusual to have trace levels of gas present during maintenance or process operations. A relay
is provided for each zone. Determine your application requirement such as fan ventilation.
The high alarm is typically used as an alarm condition for action. A relay is provided for each
zone.
The high/high alarm is common to all sensors and will activate the buzzer and strobe if ordered.
There are 2 common relays for strobe and buzzer options.
FAULT ALARM SETUP
User has the option to use relay 8 as a Common Fault alarm instead of zone 4 High Alarm.
ALARM DELAY SETUP
The low, high and high/high alarm delay for all zones are as follows:
Delay ON. This is the time, in minutes and seconds, that the relays will delay before activating
when the ppm setpoint has been reached. Delay ON is used to suppress a nuisance alarm that
may be caused by a spurious or momentary alarm of gas.
Delay OFF. The time, in minutes and seconds, that the relays will stay on after the ppm has
dropped below the setpoint. Delay OFF is used to keep ventilation fans running after the sensor
has cleared to assist ventilating any areas that may not be clear due to poor ventilation.
RELAY FAILSAFE SETUP (Press to move to next page)
Failsafe will determine if the relays are energized or de-energized during a normal operating
state (no alarm condition).
If Failsafe is YES, the relay will be energized during a normal operating condition. An alarm or
power failure will de-energize the relay to the alarm state.
When in Failsafe mode and during a normal condition, the N.O. contact is closed and the N.C.
contacts is open. WIRE ACCORDINGLY.
COMMON Hi/Hi ALARM RELAY LATCH

Model: 4200-IG User Manual Rev: 3.0
