Switched Output Control

A remote device can switch the D9142F power output on or off with a 12 VDC trigger voltage or a dry contact

closure. When +12 VDC is applied to terminal 2 of the D9142F, the power output is disabled. A dry contact device

can also disable power by shorting terminal 1 and 2 on the D9142F. If using this feature, connect the wire as

shown in Figure 11.

Use this feature to remove power from devices. This feature can apply power to notification devices that require

power during a fire alarm such as horns, strobes and bells. When used for notification appliances the power

supply must be installed within 20 feet of the control unit, and the trigger wire must be in conduit.

Select Power Output Switching

The J1 jumper (see Figure 11) enables or disables Output Control for the power output.

FCC Notice

Part 15

This equipment generates and uses radio frequency energy. If not installed and used in accordance with the manufacturer’s

instructions, it may cause interference to radio and television reception. It has been tested and found to comply with the

specifications in Part 15 of FCC rules for Class B Computing Devices.

If this equipment causes interference to radio or television reception - which can be determined by turning the equipment on

and off - the installer is encouraged to correct the interference by one or more of the following measures: 1) Reorient the

antenna of the radio/television. 2) Connect the AC transformer to a different outlet so the control panel and radio/television

are on different branch circuits. 3) Relocate the control panel with respect to the radio/television.

If necessary, the installer should consult an experienced radio/television technician for additional suggestions, or send for

the “Interference Handbook” prepared by the Federal Communications Commission.
