Light Source Wiring
5.5.1
Power Supply
Input power is supplied to Terminal 1.
The return is connected to Terminal 2 (see Figure 12).
Note:
Ensure that the light source unit will receive a minimum of 18VDC
and does not exceed 32VDC.
Pre-wiring requirements and wiring requirements are identical to the
appropriate requirements for the detector, as described in Appendix A.
5.5.2
Harness Connection
The instructions for this are identical to the detector (see Figure 11). Refer
to
on page 49.
5.5.3
Terminal Wiring
The light source contains a terminal board (see Table 6). Terminal wiring
instructions are identical to the detector wiring instructions. The light
source consists of 2 wires only. The positive supply power is connected to
Terminal 1 and the common return is connected to Terminal 2.
Connect the grounding cable to the ground terminal (Figure 12, Item 4)
outside the light source cover (Figure 12, Item 2). The detector must be
well grounded to earth ground for proper operation.
