4a. For the return-air damper (RAD) actuator, connect the positive (1) lead to TB2, terminal 6. Connect the nega- tive (−) lead to TB2, terminal 7.

b.If the actuator is factory-supplied, connect the actua- tor's 24 vac power wires to TB2, terminals 21 and 22. If the actuator is ®eld supplied, connect the power wires to a separate, isolated 24 vac power source.

Field-SuppliedTwo-Position Damper Ð The factory- supplied SPDT relay must be ®eld-installed and wired. The relay contacts are rated as follows:

48 va at 24 vac and .25 service factor

125 va at 115 vac and .25 service factor

125 va at 230 vac and .25 service factor

The relay provides a set of contacts (normally open and nor- mally closed) using no. 6 screw terminals; the 24 vdc coil connections are through 1¤4-in. quick connects.

Using a 20 AWG twisted cable, connect the relay coil con- tacts 1 and 2 to the processor module pins 41 and 42. See Fig. 48.

To connect the ®eld-supplied two-position damper actua- tor (Fig. 48): Connect one contact of the actuator to the normally-open contact of the relay. Connect the common con- tact of the relay to one leg of the power source. Connect the other contact of the actuator to the other leg of the power source.

SMOKE CONTROL OPTION Ð The smoke control option includes 3 relays which control the 4 different modes of the option. These relays are factory wired. Terminal block 5 (TB5) provides an easy means to wire the ®eld-supplied smoke con- trol panel to the PIC controller on the 39L or 39NX unit. See Fig. 49 and 50.

The approved building ®re alarm system must provide 4 different normally-open dry contact closures. A ®eld- supplied 24 vac, double-pole, double-throw (DPDT) ®re shut- down (FSD) relay rated for the application (240 vac with a 10 amp minimum) is required.

All power going through the smoke control panel dry con- tacts and the FSD relay coil is furnished by the PIC control box. A 24 vac fused power source uses a factory-installed 3 amp in-line fuse. See Fig. 49 or 50 for smoke control op- tion wiring details.

Wire as follows:

1.Disconnect all power at the unit, PIC control box, return fan (if applicable), and ®re panel.

2.Wire the supply fan motor starter per Fig. 8.

3.If applicable, wire the return fan as shown in Fig. 49 or 50.

NOTE: Return fan power may be different from supply fan power.

4.Connect leads from the return fan HOA switch to terminals 9 and 10 of TB5.

5.Wire the ®rst set of contacts of the DPDT FSD. For ®re shutdown of the unit from a local smoke detector, wire ONLY the normally-closed contacts (NEC, class 1 power rated) to the hot leg of the fan power supply and ter- minal 2 of TB1.

6.Terminal 8 of TB5 is internally connected to ground. Connect one side of the EVAC, PURG, and PRES dry contacts of the smoke control panel to terminal 8 of TB5.

7.Connect the other side of the PRES dry contact to ter- minal 3 of TB5. Connect the other side of the PURG dry contact to terminal 4 of TB5. Connect the other side of the EVAC dry contact to terminal 5 of TB5.

8.Connect the normally-open dry contacts of the FSD de- vice (smoke detector with auxilary relay and/or smoke control panel dry contact set) to terminal 1 and 2 of TB5.

9.Connect the 24 vac relay coil of the FSD relay to ter- minals 1 and 8 of TB5.

10.Connect the second pole of the FSD relay to the hot leg of the return fan power supply and to terminal 11 of TB5.

Refer to Fig. 49 or 50 for point-to-point wiring of the smoke control option inside the PIC control box.
