Area Alarm Wiring Conventions
This section provides an overview of typical wiring conventions between
MedPlus TotalAlert® Alarm Network Area Alarms and gas-specific transducers.
• Signal wires must be a minimum of 22-gauge, stranded, shielded, twisted-
pair.
If the wire runs in or passes through an area within the ceiling or air duct desig-
nated as
Return
or
Supply Air
, plenum wire may be required. Wire in these
spaces must comply with different requirements for temperature ratings, smoke
ratings, etc.
• Signal wires must be no longer than 4500\q (1372 m).
• The shielded part of the wiring from the gas-specific transducer must be con-
nected to the “G” position on the Area Alarm Breakout P.C. Board’s terminal
block. The other two wires may be connected in either the “A” and “B” posi-
tions (see figure 3-4 on page 3–13).
• When installing a MedPlus TotalAlert® Alarm Network Area Alarm, the pro-
vided gas-specific transducers must be used for proper alarm operation.
