SATEL INT-ADR 5
Use separate conductors to connect the power common for addressable modules and the
power common for detectors.
Connect to one of the detector alarm output terminals the same common ground which is
connected to the addressable module. Connect the other terminal of alarm output to the blue
wire of the addressable module.
The detector tamper contact can be connected to a separate tamper circuit (the addressable
zone should be programmed as NO or NC) or can be connected in series into the power
circuit of addressable module (the addressable zone should be programmed as 2EOL/NO or
2EOL/NC).
Figure 3 shows how the addressable modules and detectors should be connected to the
expander when the status of detector tamper contacts is to be monitored by the expander.
The wires of addressable module are marked in the figure as follows:
W – white wire (common ground),
B – black wire (data output),
A – blue wire (detector status supervision input),
R – red wire (power input).
