REMOTE SENSORS CONNECTION
The Beta gas detector has, in addition, 2 terminals "REMOTE" active
when closed, for connecting the following remote detectors (Fig.6):
- for smoke: serie RF.
- for "CO" gas: serie Beta mod. 760 CO; SE320EC e mod. 760/10 CO / SE340EC.
- for METHANE gas: serie Beta mod. 756/M; SE396KM or serie GAMMA mod.
656C/M; SE296KM or GAMMA mod. 652-O/M ; SE230KM/SE233KM.
- for LPG gas: serie Beta mod. 756/G; SE396KG or serie GAMMA mod. 656C/G;
SE296KG or GAMMA mod. 652-O/G ; SE230KG/SE233KG.
If the remote sensors are not connected to terminals "REMOTE", these
must not be modified, and therefore kept disconnected at all times.

If the remote contact remains closed for at least 20 seconds, the Beta
gas detector goes into alarm by sounding intermittently, without flash-
ing the RED LED.
ELECTRO-VALVES CONNECTION
N.O. POSITIONING FOR NORMALLY OPENED VALVES
The Beta gas detector has inside a JUMPER (J4) that permits to se-
lect the type of electro-valve to connect that can be Normally Opened
(N.O.) type or Normally Closed (N.C.) type.
We remind that the valve should be installed on the gas pipes
outside the room under control, since protection is useless if a
gas leak occurs at the beginning of the gas pipe.
Positioning JUMPER J4.

230Vac-50/60Hz
Connection of two detectors with a single electric valve is shown in
the diagrams below. It is possible to connect more than two detec-
tors, repeating the same connections.
Ex. Connection with Normally Opened electric valve (230Vac) and
a second Beta 760CO.

N.C. POSITIONING FOR NORMALLY CLOSE VALVES
Position JUMPER J4.
For normally closed electric-valves or for the con-
temporaneously check of both electrovalve and an
external electrical charge.

ATTENTION: If there is a temporary loss of power the N.C. valve
closes automatically and will need to be reset manually when
power is restored.

the diagrams below. It is possible to connect more than two detec-
tors, repeating the same connections.
