5. Use a ratcheting torque flathead screwdriver to tighten the alarm connector captive screw (above the installed wire
leads) to 2 in-lb (0.23 N-m). (See Figure 18 on page 34.)
Caution: Do not over-torque the power and alarm connectors’ captive screws. The torque should not exceed 2 in-lb
(0.23 N-m).

6. Repeat Step 2 through Step 5 to insert the input and output wires of one additional external alarm device into the
alarm connector.
Figure 19 on page 35 shows the completed wiring for two external alarm devices. The first alarm device circuit is wired
as an alarm input circuit; the IN1 and REF connections complete the circuit. The second alarm device circuit is wired as
an alarm output circuit that works on a normally open contact basis; the NO and COM connections complete the circuit.
