EXP CONFIGURATIONS - 3 Installation Options

1. Stand-Alone, Active-React Mode

Perfect for monitoring and remediating occupied or unoccupied areas.

1. Mount the unit on a wall.
2. Connect auxiliary units such as fans, vents or remote alarms.
3. Provide power to the EXP.
4. Calibrate and relax knowing that you have 24/7 gas monitoring.

In case of alarm the unit will:

Activate yellow LEDs for warning
Activate red LEDs for danger
Trigger relays to turn on fans, open or close vents or activate remote alarms

2. Controller Mode

Perfect for adding protection to existing fixed system installations.

1. Mount the unit on a wall.
2. Connect unit to existing 4-20 mA controller circuit.
3. Optionally, connect auxiliary units such as fans, vents or remote alarms.

Upon alarm the unit will:

Activate yellow LEDs for warning
Activate red LEDs for danger
Notify the central controller of the alert
Trigger the auxiliary relays to turn on fans, open or close vents or activate remote alarms (if installed)
A/C power supply not required if unit is connected to a controller.

3. Remote Sensing Mode

Perfect for monitoring either explosive* or non-explosive environments; confined spaces or unoccupied spaces.

1. Mount the base unit on a wall.
2. Remotely mount the sensor in the hazard area, up to 100 feet (30 m) from base unit.
3. Connect the sensor to base unit using remote sensor kit.
4. Provide power to the base unit.
5. Connect auxiliary units such as fans, vents or remote alarms
6. Calibrate

In case of alarm the base unit will:

Activate yellow LEDs for warning
Activate red LEDs for danger
Trigger the auxiliary unit´s to turn on fans, open or close vents or activate remote alarms, if installed
A/C power supply not required if unit is connected to a controller

* NOTE: If the sensor is mounted in a potentially explosive environment, sensor must be connected to the base unit in compliance with NEC guidelines for hazardous locations.
