Installation - Series ULD (28LO) Fire Protective Signaling Speaker
These speakers are intended to be employed in either of the following configurations:
A. For fire alarm signaling service in conjunction with a compatible Listed system control unit, the
combination of which is intended to be installed as a combination system control in accordance
with the applicable requirements of NFPA 72 and the local authorities having jurisdiction. The
amplifier, in conjunction with the tone generator located in the control unit, provides the power and
signal, either for the alarm evacuation and/or for voice communication.
B. For general (non-fire alarm) signaling service in conjunction with compatible Listed sound
recording and reproducing equipment, the combination of which is intended to be installed in
accordance with the applicable requirements of the National Electrical Code and the local
authorities having jurisdiction. The amplifier or other sound reproducing equipment provides the
power for voice communication or any other related function to the speakers.
Connection Notes: For the supervised fire system voice coil, parallel input leads are provided on
Series ULD speakers for proper utilization of the electrical supervision scheme. Connect one pair
(red and black) to the incoming line from the fire alert signal source or previous speaker.
Connect the other pair (red and black) to the outgoing line to the next speaker or end-of-line
termination device. A red jumper is connected to the 70.7V 0.5W tap when shipped from the
factory. If desired, move the red jumper to a different transformer power tap lug. See "Figure 1" on
this page for available transformer power taps.
Connection Notes: For the voice/music non-supervised voice coil, connect leads (white and black)
to the incoming line from the signal source or previous speaker. A red jumper is connected to the
70.7V 0.5W tap when shipped from the factory. If desired, move the red jumper to a different
transformer power tap lug. See "Figure 1" this page for available transformer power taps.
