Assembly of Units with Coiled
Cord Handsets
This assembly procedure is for telephones with coiled cord handsets.
After the enclosure is mounted and the system wiring is in place (refer to
Figure 2), complete the following steps:
1.
Attach system wiring to the terminal strip on the telephone chassis
assembly. See Figure 2 or 3.
2.
Install 6-32 nut in backbox. Do not tighten.
3.
Install telephone chassis assembly in backbox.
4.
Install trim ring on backbox with 6-32 wing nuts. Do not tighten.
5.
Install door assembly.
6.
Tighten wing nuts.
Notes: Telephone circuits are supervised and power-limited.
Use twisted pair shielded cable for telephone circuit wiring. For
best operation, terminate shield at FFT-7/S 24V power supply
common (-).
Maximum telephone circuit wire resistance is 40 ohms.
For (End-of-Line Resistor) ELR connection to devices with
terminals, use Resistor 71252. For ELR connection to devices with
flying leads, use Resistor 71245. In Canada, N-ELR Resistor
Assembly is required.
Refer to the fire panel manual for Underwriters Laboratories (UL)
power-limited requirements and further information.
