30 DAA2 & DAX — P/N 53265:A1 8/24/2011
DAA2 Digital Audio Amplifiers DAA2 Installation
A DS-RFM fiber module must be used to connect a DAA2 to a multi-mode fiber DVC or DAA.
Refer to “Fiber Option Modules” on page 75 for more information on this module.
Figure 2.15 Fiber/Wire DAL Configuration
FFT Riser Connections
The Firefighter Telephone Riser connections (TB7) provide for the use of firefighter telephones
(FFTs) on an analog network. They are a means of connecting various FFT telephone control
modules and devices, such as FTM-1 modules, AFAWS, FPJ or RPJ-1 telephone circuits to the
DAA2.
The FFT riser may be wired in NFPA Class A or Class B configuration. For trouble supervision,
VeriFire Tools must be used to indicate whether a riser is installed or not. SW1 must be set to
indicated whether the wiring is Class A or Class B. (Refer to page 41 for switch settings.) Class B
2-Wire configurations require a 3.9K ohm 1/2 watt end-of-line resistor (P/N R-3.9K). Class A 4-
wire configurations have an internal ELR and do not require an external ELR
There are two ways that firefighter telephones may be installed on a DAA2 FFT riser. Both
configurations have a limit of seven active phones. (Refer to the FFT appendix in the DVC Digital
Voice Command manual for more information on limits.)
1. “Install FTM” selected - FireFighter Telephones must be wired to the output of the FTM
modules. The telephone points will be SLC addresses.
NOTE: If a fiber option module is installed at a DAP, that DAP may not also be used for a wire
connection.
