1 Preliminary information
The EcoAlpa5 Control Unit enables visualization of the entire Gas Safety System and provides appropriate
output signals for the system control.
It is a control unit with five communication channels designed for collaboration with gas detectors of the XT
series.
It has outputs to connect light and sound warning devices as well as binary lines for transmission of
information about the system status. In addition, the control unit can be integrated with an external system
for plant automation, e.g. BMS. Depending on the design option the unit can also actuate the gas shut off
valve to isolate supply of gas to monitored facilities.
EcoAlpa5 Control Unit reads:
signals from gas detectors,
digital input (DI),
operator’s inputs (keyboard).
By using this information EcoAlpa5:
activates signalling devices connected (both acoustic and visual),
generates visual, acoustic indications for users,
activates system outputs (e.g. to DCS or a ventilation system),
generates shutoff signals for valve.
1.1 Types of the control unit
The EcoAlpa5 unit is available in several manufacturing options that are able to perform selected
functionalities of the system, such as:
control for the gas shutoff valve (various gas types),
switching the system over to the backup power supply voltage to continue operation of the system
when the mains voltage disappears.
