MPU – 4-channel Multizone Control Panel
SAMON code: 20-300
The MPU4C unit is a four-channel control unit (sensors)
It is the ideal solution for monitoring small / medium-sized areas where there may be the presence of toxic or explosive gases
The microprocessor electronics of the unit independently provide for each channel, through multicolor LEDs, the status of each measuring point
Suitable for the detection of HCFCs, HFCs, CO2, ammonia, hydrocarbons such as: gasoline vapors, ethanol, hydrogen, natural gas, propane and butane etc.
Functions for each channel: the sensors connected to it continuously detect the presence of gas and provide an analog signal to the control panel
Three alarm levels: one yellow (early warning) and two red (medium and high) are associated with relay outputs for remote signaling
If the LED flashes it means that the system has detected a leak, if the signal persists even after the set delay time, the light becomes fixed and the contact is activated. Features:
Microprocessor electronic unit for four channels
Status indication LED for each channel
Three independently settable alarms for each channel
Alarm delay time (4 levels) can be set
Relay output A, B, C and malfunction, 230V / 5A
Manual or automatic alarm reset
Terminals for diagnosis
"Service" function for temporary blocking of alarms
Integrated self-diagnosis
Integrated buzzer
Built-in "Fail-safe" and "Power failure alarm" function
24V dc / 150mA output for siren or lamp
Ambient temperature 0°C - 50°C
Humidity 10-95% Rh (non-condensing)
IP66 protection
Matchable sensors:
Sensors are available for various gases and measuring ranges
MP sensors specific for MPU
Transmitters with output 0 10 V or 4 20 mA
Atex certified sensors for hazardous areas
NOTE: it is allowed to connect to the MPU sensors that have a total consumption of max 10 W; excessive load can damage the control unit.
