EXP Fixed System Sensor HeadBiosystems EXP
Explosion-Proof Housing

 

Biosystems EXP by Sperian is a single gas fixed placement gas detection system that is cost effective and easy to install.

EXP installation options include:

    1.  stand alone
    2.  integrated into control systems or
    3.  as part of a larger gas detection network

EXP systems come standard with:

  • sleek, tough explosion-proof housing
  • real time LCD readout
  • integrated twin-color LEDs
  • 3 available relays
  • on-board event logger
  • IrDA communication for firmware upgrades and data downloads


    EXP Fixed System Key Features

Tough Explosion-Proof housing protects unit in harsh
       conditions or during washdowns
Integrated, twin color high-intensity LEDs: Yellow for        Warning, Red for Danger

Wide range of customizable options including: alarm
       
levels and relay modes

On-board event logger records last 128 alarm events.        Event logger has battery backup
Remote sensor option allows you to place the sensor
       up to 100 feet (30m) from base unit — allowing base
       unit to be placed in convenient location
Integrated on-board controller allows EXP to be used
       as a stand alone monitor, a remote sensing head and
       single point control unit or as a transmitter in a        larger system
Easy-to-read 3-digit backlit LCD screen displays real
       time gas readings
Unit can be wired into a controller power supply
Compatible with standard 3 wire 4-20 mA wiring
In stand-alone, single person, non-intrusive        calibration can be done at the sensor head
Sensors can be replaced without declassifying
       area
3 user-available programmable onboard relays:        Warning, Danger & Fault
Fault relay notificaton of power loss or missing        sensor
Optional alarm-latching keeps unit in alarm until        manually disarmed
Twin NPT connection ports for quick connections
       without custom fittings
Firmware upgradable via IrDA connection
Interchangeable smart sensors for easy change
       out without reconfiguration
18 month warranty

    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.
