Signal connections
To connect the signal wire, lead a suitable wire type through the second cable gland and tighten it into position
with about 35mm of cable from the bottom of the cable gland.
Remove either the three-way terminal block next to the power supply socket if connecting the detector to a
SenseNET system, or the four-
way “Bus” terminal block if connecting the detector to an alarm panel in
conjunction with the APIC addressable bus card. For example, in a SenseNET system using screened cable,
connect the screen wire(s) to the “SCN” terminal, Bus A wire(s) to the “A” terminal and Bus B wire(s) to the “B”
terminal.
If the detector is in the middle of a SenseNET chain, with input and output connections, it may be more
convenient to link the common Bus A, Bus B and screen wires to single A, B and screen wires for linking to the
terminal block.
The following illustration shows the power and signal connections to the docking station for connection to a
single SenseNET cable.
Note:
Depending on the type of cable used, it may be necessary to increase the diameter of the cable with
sleeving or insulating tape to ensure that the cable is firmly held and a seal is provided when the cable gland is
fully tightened. If a cable gland is unused it must be sealed using the bung provided with the unit.
