7.3.1.1 Emergency Power Off Switch Support
The PSR-78-9533-UA now support the ability to connect an extern power switch to turn on/off the high power
amplifier via our Alarm Input dry contact pins. This Emergency Power Off (EPO) function is an optional feature that
is only active when the function is enabled. If the EPO function is enabled, the AAI dry contact input alarm pair will
no longer function. This feature is available on firmware version 2.0.33 or higher and older repeaters can be
updated using a field upgradeable firmware.
On the dry contact alarming cable, if the Alarm Input-1 & GND (light blue pair) is an open circuit, the DL and UL
HPA will be turned on. If this pair is shorted together (closed circuit) then the DL and UL HPA will turn off. If
needed, the cable length can be extended up to approximately 300 ft. using CAT6 Shielded Twisted Pair cable.
