replaced while the system continues to sense the inputs from
the remaining module.
In certain applications it may be possible to connect single fire
detectors to redundant input modules. For consideration of
this option, consult the factory for details.
Field Wiring
Field wiring terminal blocks on the I/O chassis are used to
connect the field power supply and field input wiring to the
module. The terminal blocks are located directly above and
below the slot where the module is installed. Each terminal
block consists of ten #6 wire clamp screw terminals capable of
holding two 12 AWG wires.
The field power supply voltage is internally regulated inside
the module. This power is used to source the power to the fire
detector inputs. The return side of the inputs are wired back
to the field power supply returns.
Figure 3 shows the proper connection of input signals to the
input wiring terminals.
