General Background
Automatic Fire Alarm Warden Station (AFAWS-Series) telephones are
compatible with the FFT-7 and FFT-7S master telephone stations. The
series has a handset with a push-to-talk switch, a hearing aid-compatible
speaker, and an indicator that illuminates when the warden station is
connected to the master telephone station. Up to seven handsets
(including the master handset) may be operated simultaneously. AFAWS
components are illustrated in Figure 1.

System Wiring
Telephone system wiring, from the FFT-7/FFT-7S through the control
point such as the XPM-8 to the warden’s station, must not be connected to
or run in the same conduit or cable tray as Signal Alarm Circuits (SLCs),
speaker circuits, strobe circuits, cable TV, or other noise producing
circuits.

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.

Assembly of Units with
Armored Cable Handsets
This assembly procedure is for telephones with armored cable handsets.
Complete the following steps when the enclosure has been mounted and
the system wiring is in place (refer to Figure 3).
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. Inset armored cable end into slot on top of telephone chassis assembly.
4. Install telephone chassis assembly in backbox.
5. Install trim ring on backbox with 6-32 wing nuts. Do not tighten.
