It is essential that the installation is carried out in the order given
below to ensure the correct operation of the system.
First read the system description sheet before following the
instructions below
1.
Connect the gas valve to the marked terminals “gas valve”
.
2.
Connect current monitors where required (
7 & 8 on diagram
)
3.
Connect the pressure sender unit to the marked terminals (
10
)
4.
Connect any additional EM stop buttons or thermal links in series to the terminals marked “EM stop” (
6
)
5.
Each detector/device has a rotary address switch, each switch should be set to a different number or letter starting with “0”.
Then connect the gas detectors to terminals marked “detectors” on the panel. Detectors are wired in parallel. “Daisy
chain” (
11 & 12
)
6.
Connect fire alarm, ensure potential free n/c (
13
)
7.
Connect 0-10 volt to speed controllers 0-10 volt inputs where required (
14
)
8.
Ensure any BMS connections are made to the relays (
15
)
9.
Connect the 3 amp fused spur 240 volt supply to marked terminals.
10.
At this point check that the sender unit has been fitted to the control valve and that gas is available
11.
Once power is connected to the panel the detectors will flash the green LEDs for 90 seconds after which the LEDs will be on
continuously.
12.
Press the “learn field button” (
23
) this is on the main circuit board on the right hand side, just over half way up the board
pressing this once allows the panel to learn how many and which type of detectors are fitted.
13.
Press and keep pressed the “display detectors” button whilst checking on the LCD display that all the detectors have been
recognised by the panel. A recognised detector will appear as “
CO
” Carbon Monoxide, “
CM
” combustible, “
CH
” Carbon
Dioxide, “
OX
” Oxygen depletion and “
TP
” Temperature. Count the number of “seen” detectors on screen and ensure total is
the same as the number of detectors installed. “
NM”
in the third column means that number is not monitored. If more than 8
detectors are fitted then press both the “display detectors” and the “pressure” buttons together to view the next 8 detectors.
Note
that a detector set at 0 appears as 1 on the LCD and a detector set as 1 appears as 2 on the LCD etc.
14.
At this point turn the on/off switch to the on position press the “gas” button, the panel will test to ensure gas tightness and
provided there are no leaks the panel will allow gas through and the gas on LED will light. Should the gas test fail then press
the pressure button to see the pressure in mbars on both sides of the valve. Thus you can see the pressure drop
downstream provided the valve is closed
15.
Check that the panel can see the smallest allowable pressure drop if it does not then increase the proving time by adjusting
the blue rotary dials (prove time) on the circuit board and or by switching on SW=X2
(16)
16.
Check the operation of the electric contactor by pressing the ’Electric’ button on the panel lid to switch on and off.

Notes.
It is recommended that all systems are commissioned a er installa on by Medem UK. This will extend the warranty period from 5
years to 10 years and ensure the system is working as designed.
