1.4 Operating Principle
control unit for detecting toxic and/or inflammable gases in a commercial or
light industrial building (e.g. underground car parks), so that action can be taken. It allows
ventilation to be actively regulated, in particular. It has six detection inputs and up to four
alarm thresholds that can be configured independently for each input.

concentration of gas detected in the air.
The unit can send commands to one or more pieces of connected safety equipment when
the configured alarm thresholds are reached, e.g., to do the following:
▪control the ventilation (air blowers or extractors)
▪cause a siren to sound
▪cause a LED warning panel to light up
▪send a command to a CTM (Centralised Technical Management) system

technical fault once any unusual use of the unit or a detector is detected. This function thus
ensures the reliability of the gas-detection system installed.

2.1 Precautions for Use
For your safety, ensure that you are working on a device that is powered off before you do
anything!
cables can be inserted from the top, or in such a way that they can be inserted from the
bottom. However, in order to guarantee optimal sealing, it is recommended that you always
insert the cables from the bottom.
The housing of the device is IP65-certified and is therefore protected against the presence of
dust and water, provided that the installation instructions are followed.
The housing has a number of machined apertures. You will need to clear these machined
apertures with a flat screwdriver and hammer in order to insert the cable glands.
2.2 Placing the U•V6 unit

If you choose to fix the device without using the feet, attach the housing via the four holes
provided for this purpose to the four corners of the housing using a PZ2 screwdriver that is at
least 150 mm long.
See the quick installation guide provided for the different steps.
2.3 Connecting the control unit
The unit must be installed and the electrical connections hooked up by a qualified technician,
in accordance with the instructions given in this manual and on the diagram on the back of
It is recommended that you place the circuit breaker in the vicinity of the equipment.
Any installation must comply with the applicable local standards and regulations, in particular
as they pertain to the type of cable and the cross-sectional area of the wires to be used.
Ensure that the wires are securely connected to the connectors when connecting the
electrical terminals. Use a maximum torque of 0.60 Nm. To ensure electrical safety, the
wires that go from the cable glands on the housing to the terminals on the board must not be
longer than 70 mm.
It is recommended that you always use wires with crimp ends, in order to avoid any risk of
bad electrical contacts.
Exam
A circuit breaker (2 pins, 6A, 250V (AC)) must be placed on the live and the neutral. See
the wiring example below.

mode, the current leaves via terminal Sand returns via terminal V-.
The analogue output is configured as follows before leaving the factory:
▪In 4-20 mA current-loop mode
▪The output signal corresponds to the maximum value of the 6 input channels
▪The output gain ratio is 1:1 of the detectors' measurement range. A full-scale
measurement of the detector is shown as 20 mA on the analogue output signal

The LEDs on the motherboard must light up when the device is powered on. It is important
that the user checks that these are all green and not flashing, except for the yellow LED on
the right-hand side of the motherboard, which should flash on and off at one-second
intervals.
Immediately after the unit is powered on, the LCD screen on the unit must turn blue and the
buzzer should sound a short, uninterrupted sound.
All activated detection channels -when the unit is turned on. The
measurements on a channel in a warm-up state are ignored. The warm-up state has a finite
duration which depends on the target gas configured.
The useful lifespan of a standard battery is estimated at four years. It is essential to replace
it after that. If a battery is defective, its charge is inhibited to avoid damaging it.
The unit may place itself in an unknown status during this operation. As a result, it
may be necessary to restart it correctly by pressing the Reset button on the motherboard.

2. Select the appropriate "standard config."
3. [Optional] Select the target gases and alarm thresholds for each input channel
4. [Optional] Adjust the settings specific to the installation.
3.2 Addressing the Relays
Relay addressing involves connecting the alarm conditions configured with actions to open
or close contacts on the alarm relays. Depending on the requirements of the installation, a
standard configuration can be selected and, as a result, the appropriate devices can be
activated in the event of a gas detection.
These standard configurations come as presets, which are stored in the unit's memory. A
technician, who has been trained and certified by Dalemans, can activate the most
appropriate standard configuration for the installation during commissioning.
These operations require the intervention of qualified technicians. Contact DALEMANS
for more information.
The PENxx standard configurations have been designed in accordance with EN 50545-1.
However, any subsequent modification may impact compliance with this standard. Please
contact your DALEMANS representative for more information.
