92 DAA2 & DAX — P/N 53265:A1 8/24/2011
DAA Digital Audio Amplifiers Overview
1. Find the rated dB loss per foot within the cable manufacturer’s specifications. Determine
the total attenuation between the two nodes due to the cable.
Loss = (loss/ft.) x (length in feet)
2. Establish the dB loss for each connector and splice. Sum all the losses.
3. Total the attenuation factors obtained in steps 1 and 2. This will provide an approximate
attenuation total. The actual attenuation can be measured end-to-end with fiber-optic
industry standard equipment using a test wavelength of 850 nanometers (multi-
mode)/1300 nanometers (single-mode).
The Maximum attenuation*:
4.2dB for multi-mode with 50/125 micrometer cable @ 850 nm.
8dB for multi-mode with 62.5/125 micrometer cable @ 850 nm.
5.0dB for single-mode with 9/125 micrometer cable @ 1300 nm.
* Use for connections between DVCs and DAAs only. Refer to “Fiber Option
Modules” on page 75 for information on DAA fiber connections to the DAA2 and
DAX.
 Alarm Bus - TB4
Power-limited by source.
Non-supervised.
Recommended wiring: 14-18 AWG twisted-pair.
Requires 16VDC minimum @ 20mA across the terminals to activate.
 Trouble Bus - TB5
Dry contact.
Common, non-supervised, contact rating 2A, 30VDC.
Recommended wiring: 14-18 AWG twisted-pair.
 FFT Riser - TB7
Power-limited output.
Supervised.
Class A (Style Z) or Class B (Style Y) operation.
Style Y 2-wire connections require a 3.9k ohm 1/2 watt resistor (P/N R-3.9K).
Max. wiring resistance (including individual telephone zone to last handset) permitted is 50
ohms, 10,000 ft. (3048 m) max. wiring distance at 14 AWG to last handset.
 Auxiliary Input A (AUX A) - TB 9
Signal strength from low-level analog audio input (such as background music or telephone
paging): 1V
p-p
max. Optional supervision through programming.
Recommended wiring: 14-18 AWG, twisted-pair.
Supervision programmable.
Auxiliary input source must be within 20 ft. ( 6.1 m) of the DAA, and within the same room.
 Auxiliary Input B (AUX B) - TB 8
Signal strength from low-level analog audio input: 12V
p-p
nominal, 15V
p-p
max.
Recommended wiring: 14-18 AWG twisted-pair.
Supervision programmable.
 Speaker Circuits - TB10, TB11, TB12 and TB13
Power-limited outputs.
DAA-5025/70 - 50 Watts dynamically shared among the four outputs.
DAA-7525 - 75 Watts dynamically shared among the four outputs.
Supervision determined by programming.
