Andel-Floodline refrigerant gas sensor FGS 1000; Can detect all HFC gases with scope for others subject to calibration.

The Floodline FGS1000 Refrigerant Gas Sensor can be used as a stand-alone refrigerant alarm system OR be included as part of a larger water/oil leak detection system.  It can also be used to provide a dedicated refrigerant gas detection alarm package.

The Floodline FGS1000 complies with BS EN378 and detects refrigerant gases to H S E Occupational Exposure Limits.  The sensitivity controls are calibrated with 1000ppm gas to air mixture using the specified gas (R134A, R404A, R407C, R410A).  Other gases can be accommodated subject to calibration.

BS EN378 specifies the installation of fixed refrigerant leak detectors in both existing and new systems of all sizes (with certain exceptions).

The Floodline FGS1000 sensors are connected to a standard Floodline Control Panel giving audible and visual alarm features in addition to the facility for onward communication to BMS etc.

Applications:
VRV Air Conditioning systems
Refrigeration compressor packs
Machine/Plant Rooms
A/C Service Tunnels
Hotel Bedrooms
DX Split Units

Detection:
Constant monitoring of the area for any build up of chosen refrigerant gases above a preset level – When a leak above the preset levels is detected, audio/visual warnings are given by a pulsing 85dB sounder along with amber LED for “LEAK” and red LED for “ALARM”.

Audible & visual alarms also at central Floodline Control Panel.

Construction:
Powder coated metal enclosure


Dimensions:
H: 130mm  x  W: 84mm  x  D: 60mm

Fixing:
Wall/surface mounted at suitable height based on occupancy of room being monitored & refrigerant gas being detected.

Operation:
The Floodline FGS1000 can be preset to several different modes of operation based on position of 3no dip switches:

Operational Modes:
Default Mode:   In ‘Leak Alarm’,  warning is given by pulsing 85dB sounder, ‘LEAK’ LED illuminates Amber & ‘ALARM’ LED flashes red & integral relay de-energises. Once gas concentration falls below preset level, ‘LEAK’ LED illuminates green. Pressing the Reset Button causes ‘LEAK’ LED to go off and the relay re-energises.

Sounder Disabled:   As per Default Mode but local audible alarm is disabled.

Manual Mode:   As per Default Mode but sensor resets automatically once concentration falls below preset levels (if the Mute Button has been pressed).

Automatic Mode:   As per Default Mode but system will reset automatically once concentration falls below preset level.


Specification:
Supply:           24VAC OR 230VAC

Relay Outputs:       DPCO (3A @ 230VAC)

Indicators:        5mm LEDs

Sounder:        85dB piezo
