OVERVIEW
The Hansen Gas Detection Controller, HGD-C-2
and HGD-C-8, is intended to be used to provide
audio-visual alerts and information on the status of
a network of gas detectors in a centralized location.
This allows clear at-a-glance visualization of any
alarm or fault status on a connected gas detector in a
location outside of the monitored space, as required
by many regulatory codes and standards.
This Controller displays comprehensive information
about the status of all connected gas detectors.
A maximum of (8) Hansen gas detectors can be
connected to the HGD-C-8 Controller via MODBUS
RTU and a maximum of (2) Hansen gas detectors to
the HGD-C-2
The Controller can be used to provide power to each
connected, compatible gas detector, negating the
need for separate power supply at the location of the
gas detector.
The HGD-C-8 Controller displays status via an LCD
screen and LEDs, (The HGD-C-2 only displays status
via LEDs on cover) for each connected gas detector,
status is clearly indicated via dedicated LEDs to
indicate:
- Power & connectivity
- High alarm
- Low alarm
- Fault
The Controller provides an interface by which you can
monitor, acknowledge alarms, and observe conditions
inside the mechanical room. The HGD-C-8 LCD screen
will display the current gas reading and gas type for
the selected channel, or will indicate fault and/or alarm
status. The LCD screen is also used for configuration of
the Controller via the integrated keypad. In addition to
the visual alarm status displayed, the Controller includes
an integrated audible alarm. An optional audio-visual
alarm beacon can be installed, mounted in the top of the
enclosure, to enhance local alarm indication.
The Controller provides SPDT relays (indicating any high
alarm, low alarm or fault status) and can act as a MODBUS
slave device. This allows connection to a third-party
device such as a Building Management System (BMS)
or Programmable Logic Controller (PLC).
Data logging is available on the HGD-C-8 via the integrated
SD card, which can be removed to allow download of
the logged data to a computer.
