Application
Duomo is recognised within the gas industry for
providing a comprehensive range of low cost, high
reliability gas detection for many applications. We
have installed and commissioned natural gas and
carbon monoxide sensors in applications such as
boiler rooms, kitchens, car parks, aircraft hangers,
factories and shopping centres. The HCF100 is the
freon gas sensor used with the complete range of
Duomo detector panels. All Duomo products are
manufactured to meet relevant European
Normatives and proposals for explosive and toxic
gases.
Operation
When the HCF100 senses the presence of freon gas
it sends a 4 - 20mA signal to the detector
proportional to the level of gas. The detector then
operates a pre-alarm relay used for remote sirens or
visual indicators if the level of gas continues to rise.
The main alarm relay is activated to break the
electrical supply to a safety shut off valve, and is
fixed at 300ppm of freon R134a.
Features
The HCF100 is controlled by a microprocessor. This
conducts both self diagnostics and automatically
calibrates the sensor when ambient conditions vary,
thus avoiding false alarms. A hand-held datalogger
can be connected to the HCF100 and information
about the sensor can be read and printed out i.e.:
the serial number
the sensor condition
how many times the sensor has been powered up
how many alarms have occurred
date of manufacture
present temperature of the device
the preset calibration state
* The HCF100 can be configured to work with a
large number of freon gases. Contact us to find out
more.
CAUTION! Carefully read the following instructions
prior to installation of this device. Always keep this
pamphlet for future reference. Ensure that the gas
detection system is wired correctly and is only used
for the purpose for which it is intended.
i DO NOT TEST THIS SENSOR WITH ANYTHING OTHER THAN
DUOMO TEST GAS. Concentrations above this will damage the
sensor and shorten sensor life.

Electrical Installation
HCF100 PCB Layout
This sensor is designed to be connected directly to
Duomo gas detector controls (BX150, GS100M, GS300M
and BX444M). These are safety devices and are designed
to give audible alarms and automatically provide
latched electrical isolation of associated gas safety shut
off valves. The sensor can be located up to 100m from
the gas detector. Cable size should be 1mm2 csa. If the
sensor cables are run seperately in specific conduit it is
not essential to use screened cable but if the cables are
routed through conduit or trunking containing other
wiring the use of screened cable is advisable. The wiring
should be performed by a qualified person in
accordance with current regulations. The plug in
terminal rail makes installation easy and quick.
Check wiring before powering up the system.
In Case Of Alarm
Extinguish any naked flames.
Do not switch lights or electrical devices on or off.
Open all windows and doors to increase ventilation.
If the audible alarm changes from continuous to
intermittent the levels of gas have dropped. A
responsible, qualified person is now safe to find the
cause of the alarm.
If the alarm sound remains constant, and the cause is
not evident or possible to eliminate turn off the
emergency isolation valves to the area and contact
your gas provider emergency line. They will advice
accordingly.
