7. To use the ceiling tamper, loosen the tamper post

(Item 5 in Figure 4) by cutting the three tabs and

mount the post to the ceiling using a 0,42 cm screw

(Figure 5).

8. Attach the cover, if removed, and close it.

9. Use the cable ties (Item 6 in Figure 4) for strain relief.

4.0 Wiring

Apply power only after all connections are

made and inspected. Do not coil excess

wiring inside detector.

If necessary, connect the alarm and tamper contacts to a

safe extra low voltage (SELV) circuit only.

Refer to Figure 6 for terminal identification.

Terminals 1 (-) and 2 (+): Power limits are 9 VDC to

15 VDC. Use no smaller than 0,8 mm wire pair between

the unit and power source.

Terminals 3 (NO), 4 (C), and 5 (NC): Alarm relay

contacts rated at 125 mA, 28 VDC maximum for DC

resistive loads. Use Terminals 4 and 5 for the

normally-closed circuits. Do not use these terminals

with capacitive or inductive loads.

Terminals 6 (T) and 7 (T): Normally-closed tamper

contacts rated at 28 VDC, 125 mA.

Terminal 8 (M): Memory Mode requires activating a

supply voltage on Terminal 8. Refer to Section 8.0

Memory, Day Mode, Night Mode, and Remote Walk Test on

page 5 for operating and wiring information.
