Installation
Before installing Page/Party™ equipment, design the system layout taking into consideration personnel
safety, operational function, convenience, and power cable length. System cable length (power
conductors) requirements for 115 V ac systems must be calculated by determining the overall voltage
loss due to cable resistance and individual station voltage drops. The end of line station requires a
minimum operating voltage of 90 V ac.
A separate power feed is recommended to each station located in hazardous areas. With a separate feed,
individual stations can be de-energized for service or maintenance without affecting the power supply
and operation of the other stations in the hazardous area.
