Warning/Caution Notations

WARNING:
Personal injury or loss of life may occur if you do not follow a procedure as specified.

CAUTION:
Equipment damage or loss of data may occur if you do not follow a procedure as specified.

Required Tools

• 6 mm hex wrench
• No. 2 Phillips screwdriver
• Drill
• 1/4-inch (6.4 mm) hex driver
• 10 mm socket or box wrench

Prerequisites

WARNING:
Do not open the actuator housing.

CAUTION:
Continuous use at voltages above the recommended tolerances may damage the actuator.

Installation

Figure 4. Fasten the Shaft Adapter to the Damper Shaft.

CAUTION:

• Use a 6 mm hex wrench to center the damper shaft by turning the socket head screw.
• Use a 10 mm socket or box wrench to apply 97 in-lb to 115 in-lb (11 Nm to 13 Nm) of  torque to both coupling nuts to clamp the actuator to the shaft.

Wiring

NOTE: All wiring must conform to NEC and local codes and regulations.

24 Vac

**120 Vac

**

**230 Vac

**

CAUTION:
These AC powered actuators must be wired with Line referenced with respect to Neutral, as indicated. The ground lead must be connected for proper protection of the actuator. Any other connection, such as phase-to-phase, can damage the actuator.

Fixed Dual End Switches.

NOTE:
Both sets of contacts are open when actuator is between 5° and 85°.

CAUTION:
Mixed switch operation to the switching outputs of both fixed dual end switches (5° and 85°) is not permitted.

Either AC line voltage from the same phase must be applied to all four outputs of the fixed dual end switches, or UL-Class 2 voltage must be applied to all four outputs.

Electronic Fusible Link (EFL)

All GVD/GKD Electronic Damper Actuators are EFLcapable. EFLs are purchased separately. See Table 1.

Table 1. Electronic Fusible Link Product Numbers.

NOTE:
All EFLs are low voltage and do not need to be wired in conduit.

To install an EFL, do the following:

1. Remove and discard the cover marked EFL.

2. Use a small, needle-nose pliers to squeeze the release lock of the jumper plug and remove the jumper plug.
   NOTE: Remove the entire jumper plug, including the wire loop.
   

3. Insert the quick connect plug from the EFL and ensure that the cable is secure.
   
   NOTE:
   If you are not using an EFL, do not modify the actuator. An EFL or jumper plug must be installed for actuator to work properly.

Maintenance

CAUTION:
The GVD/GKD actuators do not require any periodic cycling to function properly as an integral part of an active smoke control damper system. The National Fire Alarm Code NFPA 72 states that all life safety systems are to be functionally checked at least annually. Check the smoke control damper/actuator every time you functionally check your smoke detectors, emergency lights, and/or power generators for operation.
