Specification
Use
The Unipoint controller provides integrators with a flexible and low cost solution to the many applications
requiring flammable, toxic or oxygen gas detection to be incorporated into their control systems. Unipoint
is designed to use industry standard DIN rail allowing it to be easily installed into many different types of
plastic or metal, indoor or outdoor, hazardous or non hazardous area enclosures. It is designed for use
with any mV flammable gas detector as well as any 2 or 3 wire 4-20mA gas detector (subject to overall
power requirements).
User interface
Operation
Two pushbuttons for normal operation of resetting alarms and initiating self diagnostic test of system.
Four buttons for user programmable functions via intuitive menu
Backlit display
Units of measure, digital gas reading and event code
Other indication
Ultra-bright steady/flashing LEDs subject to condition; alarm (red), power (green), fault (amber). In-built
audible alarm 63dB at 0.3 meters.
Termination
Easily accessible plug in screw type terminals. Terminals accept maximum wire diameter 1.5mm2
