Connecting the Detector
8 Connecting the Detector
The terminal block of the Detector SC100 should be wired correctly before the detector cover has
been fixed.
It is recommended to follow the steps below to wire the pins on the terminal block:
1. Bring and feed the cable through the grommet and cable inlet, see
Figure 7-1 Function
modules on Detector Base
for reference.
2. Cut and strip the cable, leaving approximately 10cm of wires after the strain relief.
3. Remove the wire insulation about 6 mm.
4. Wire the terminals according to wiring diagram below.
Figure 8-1 Wirings on the terminal block
Note
The open collector alarm output (terminal 8) will be active low during alarm.
5. Connect the detector to the panel according to the actual applications: See
Figure 8-2
for
connecting the detector to a zone configured as Dual-End-of-Line and
Figure 8-3
for
connecting the detector to a zone configured as Single-End-of-Line.

Note:
When this wiring diagram
is used, RT still can be used for
tamper loop, but the jumper on
RA needs be removed and the
external EOL resistor has to be
connected to alarm loop.
