1.0  GENERAL INFORMATION
This manual shows you how to safely install, operate and use the device.
The instructions for use ALWAYS need to be available in the facility where the device is installed.
ATTENTION: installation/maintenance needs to be carried out by qualified staff (as explained in
section 1.3) by using suitable personal protective equipment (PPE).
For any information pertaining to installation or in the event of problems that cannot be solved with the instructions, contact
the manufacturer by using the address and phone numbers provided on the last page.
1.1  DESCRIPTION
Device that, combined with a gas safety solenoid valve, controls its closure in the event of:
•seismic event (with analysis over time and based on the frequency of the accelerations on the 3 axes)
•remote control (e.g. gas detector, emergency closure)
The device has a relay alarm output that can be used for remote signals and to disconnect the power supply, thus eliminating
any sources of ignition or explosion. The sensor can be connected electrically to normally closed/open solenoid valves with
manual reset (also already installed).

4.0  ELECTRICAL CONNECTIONS (see diagrams fig. 3 and 4)
They must be carried out with the system stopped and NOT electrically powered.
•Prior to carrying out any electrical wiring operations, make sure that the mains voltage matches the supply voltage indicated
on the product label.
•
NOTE: The wiring operations must be carried out ensuring the product's IP65 protection rating ;
•Undo the fixing screws (8) and remove the cover (9).
•Connect the power supply to the power terminals and the earth cable to the terminal using the appropriate cable
terminals. The 12 V and 24 V versions can be powered both with direct current and with alternating current. The connection
terminals are not polarised.
• For the electrical connection, use the cable indicated in the valve instruction sheet:
• Relay for alarm/failure output max 0.5A resistive:
N.O. : Normally open contact
C: Common contact
N.C.: Normally closed contact
• Normally closed contact - EXT IN
Contact to be used for connection with gas leak detector or for emergency closure button. The contact is dry and must not
be powered.
• After making the connection put the cover (9) back in its original position and fasten it using the relevant screws (8) making
sure that the gasket (10) is inside the groove.
5.0  DIP SWITCH (6)
MADAS®seismic sensors are suitable for use with normally open (N.O.) or normally closed (N.C.) valves.
The type of solenoid valve is selected via the internal DIP switch
DIP switch no. 1: (solenoid valve type selection):
ON = N.C. solenoid valves
OFF = N.O. solenoid valves
DIP switch no. 2 (sensitivity selection):
A2 = normal
A1 = increased sensitivity
EXAMPLES
• Configuration for N.C. solenoid valve (DIP Switch 1 -> ON)
and normal sensitivity (DIP Switch 2 -> A2)
• Configuration for N.O. solenoid valve (DIP Switch 1 -> OFF)
and normal sensitivity (DIP Switch 2 -> A2)

6.0  STARTUP AND RESET
• Press the reset/test button, for about 1s, until the POWER LED turns on, then proceed with the reset (opening) of the
solenoid valve referring to the valve instruction sheet;
• After activating the system, check the operation of the device by running a system test;
• To run a system test press the reset/test button, for 5s: the solenoid valve will close the gas flow and the red alarm LED
will light up;
• After the reset or start-up, the device runs an internal self-test identified by all the LEDs lighting up in sequence. During
this phase the device must NOT be subjected to vibrations. After the activation of the POWER LED with a steady light, it
is possible to proceed with the reset (opening) of the solenoid valve.
7.0  MAINTENANCE
• Device M90: no maintenance is required
• Solenoid valve: refer to the solenoid valve instruction sheet
