NOTE:
If the DISS demand check thread size
is not compatible with the existing tubing
connection; use the included fitting kits to
adapt as needed. Fitting/adapter kit needs
to be installed upstream from the DISS con-
nection at the gas sensor.
6. Install the gas specific transducer.
7. Tighten the DISS nut until you feel resis-
tance.
8. Repeat steps 3-7 until all of the gas spe-
cific transducers are installed.
9. Verify that the gas specific transducers are
in the appropriate places by referring to
your records from the disassembly.
10. Return pressure to each gas sensor, one
gas at a time and check for leaks. Make
any adjustments or corrections as needed.
NOTE:
Remote sensors can also be in-
stalled in compatible BeaconMedæs Zone
Valve boxes with additional adapter kit
(4107401625). One required for each sensor.
5.3.5 Install I/O Modules
1. Position the Input/Output modules in
the rough-in box to verify the fit prior to

2. Mount each I/O module using the pro-
vided nuts or self-drilling screws.
3. Connect the grey cable(s) provided; from
the Power Supply to the white sockets on
the I/O modules in a daisy chain manner
(See Figure 122).
4. The last module in the chain needs to
have the #1 DIP switch set to “ON” (See
Figure 123). Refer to the module ID label.
5. Connect all input signal / output signal /
gas sensor wiring to their respective mod-

5. Connect the supply power Line and Neu-
tral wires to the terminal block.
6. Connect the supply power Ground wire

NOTE:
Alarm panels require 100 to 250 VAC
50/60Hz power. Refer to wiring schematics
located on the quick setup guide included.
