The RMS systems allow for asset location tracking and geofencing via a secured website (a geofence is a
virtual barrier which is set in the GPS software). The battery bank voltage can also be remotely monitored.

Both forms of emergency vehicle preemption (EVP) listed below provide priority to the signal controller
at which the detection event occurs. Any con
fl
icting phases displaying green are immediately terminated.
After which, the corresponding red clearance interval is served and the approaching emergency vehicle
is given a green indication. This green indication is held as long as the EVP detection is present. Once the
EVP detection is no longer present, traf
fi
c control resumes, as programmed. Both forms of EVP detection
can be equipped with a 4 inch (10.16 cm),
fl
ashing white
fl
oodlight. This serves to notify emergency
vehicles of detection and that priority has been placed on their approach.
Strobe Detection
The emergency vehicle uses a special strobe light to transmit a continuously
fl
ashing optical signal. The
detector receives this signal, and if the signal format is correct, it will notify the traf
fi
c controller of a
request for priority.
Audible Detection
The audible detector can detect ‘Class A’ sirens (Yelp, Wail, Hi-Lo) of an approaching emergency vehicle
and the direction from which they are approaching. It will notify the traf
fi
c controller of a request for
priority.

This hardware serves as an interface to permit connection of the PTL 2.4x to a 110 VAC intersection
controller. This allows the 110 VAC controller to operate the signal lamps on the PTL 2.4x. This requires a
hardwire connection from the intersection controller to the PTL 2.4x unit(s).
