General Information
This publication contains information relating to Model MOD5300A, MOD5400A, and MOD5500A
Call/Talk Stations. They consist of the following subassemblies:
A01B B01B B02B B04 C01B D01B
System layout should be planned in advance of installation. Stations should be located carefully, taking
convenience, accessibility, and personnel safety into account. The quantity and location of paging speakers
must be carefully considered, particularly in areas of high ambient noise or reverberation. The speaker
amplifier built into each station drives one horn-loaded paging speaker. If additional paging speakers are
needed, separate speaker amplifiers can be added to the system. In quiet areas, such as offices, several
paging speakers can be connected to a single station. Please see publication 42004-135 Speaker/Horn
Installation for GAI-Tronics Communication Systems or consult a GAI-Tronics sales representative for
additional system planning information.
All units are wired in parallel. Good planning will minimize the cable required for each installation.
GAI-Tronics can supply multi-conductor cable designed especially for this application. The number, size,
and color coding of conductors are listed in the accompanying system connection diagrams. Standard cable
has 600-volt insulation and is UL-rated for power cable tray use. The maximum standard cable length is
5,250 feet (1600 m) from the line balance assembly. For larger systems or non-standard cable, please
contact a GAI-Tronics representative.
The cable described above includes conductors to provide ac power to each station. All stations operate
from a common source, enhancing reliability, particularity if no other ac load is placed on the circuit
breaker or branch line feeding the system. This configuration also allows easy transfer to an emergency
power source in the event of a power failure. However, if preferred, each station may be individually
powered from a nearby nominal 115 volt, 50 or 60 Hz single-phase outlet.
WARNING
Do not install in any hazardous locations; such installations may cause a safety
hazard and consequent injury or property damage.
NOTICE: Effective Jan. 1, 2005, the Call/Talk communication system and its components will not
maintain any nationally recognized laboratory approval for hazardous locations.
