FOR-22 Dual 4-Wire Interface Instruction Manual

INSTALLING THE

FOR-22 INTERFACE

This chapter includes the following topics about installing the FOR-22

interface:

• Overview of interface frames and power supplies.

• Installing the interface in an interface frame.

• Wiring the interface to the matrix and to external devices.

• Adjusting the interface’s front-panel controls after installation.

INTERFACE FRAMES AND POWER

SUPPLIES

Interface modules convert the 4-wire signals of a central matrix port to

some other form of communication, such as for telephones, camera

intercoms, two-way radios, and so on.

Each interface module connects to both the central matrix and to the

external device through cable attached to hardware connectors on the

rear of the interface module. To house these interface modules,

Clear-Com offers various types of interface frames. The two interface

frames which can house the FOR-22 dual 4-wire/radio interface are

the IMF-3 and the IMF-102 frames, which are described below.

IMF-3 Interface Module Frame

The IMF-3 interface frame holds up to 11 interface modules in three

rack units (3 RU) of a standard Electronics Industry Association

19-inch wide (48.26 cm) rack. The frame holds a modular,

rear-mounted connector panel for each interface, containing two RJ-45

connectors for connecting cable to matrix ports, and two DB-9

connectors for connecting cable to external devices. Figure 2-1

illustrates the rear panel of an IMF-3 interface frame, with 11

rear-panel assemblies installed.

The frame uses an external PSU-101 rack-mounted power supply to

supply power to the interface modules. A second PSU-101 can be

attached for redundancy.

As a rule-of-thumb, one PSU-101 power supply unit is required for

every two IMF-3 frames. A PSU-101 power supply unit requires 90 to

260 VAC at 45 to 65 Hz with a maximum dissipation of 80 watts. A

PSU-101 connected for redundancy requires very little current unless

used.
