UL 325 MONITORING REQUIREMENT FOR EXTERNAL ENTRAPMENT PROTECTION DEVICES
UL 325 Monitoring Requirement for External Entrapment
Protecon Devices
In accordance with the UL 325 standard, aer July 31st, 2018, all bi-fold gate operators will need a minimum
of 2 external entrapment sensors (1 open direcon and 1 close direcon) installed before automac
operaon is allowed, but all potenal entrapment zones must be protected or eliminated.
ALL external entrapment protecon sensors including non-contact (Photo Eyes) and contact (Edge) sensors
must be monitored, and the operator must verify the presence of every device at least once during each
open and close cycle.
Terminal 40 in the SpeedGate operator enclosure terminal strip is designated for monitoring of all external
entrapment sensor connecons by looking for NC contacts connected to input terminals and cycling the
power.
Addional sensor inputs, if required, can be made available by installing addional blocks on the I/O
expansion board.
Upon monitoring, should any device not be present, or a fault condion occur that precludes the sensing
of an obstrucon, including an interrupon of the wireless signal to the wireless device or an open or short
circuit in the wiring that connects the external entrapment device to the operator and the device’s supply
source, the operator shall funcon with constant pressure for the direcon of travel being protected, or
shall only be able to be moved manually.
The gate operator monitors the “presence” of each entrapment protecon sensor. When the operator no
longer detects a sensor, it will cease automac operaon in the direcon of the missing or failed sensor.
Qualied personnel must be physically present at the site of the gate system to troubleshoot monitoring
faults. If a fault in the entrapment protecon system is detected, fault number 928 will appear on the
boom le of the operator panel LCD diagnosc display. Refer to “F.928” on page 126 for troubleshoong
details.
When the fault or error is resolved, a normal command for a new open or close cycle will restore gate
operaon.
Prior to resuming normal operaon, it is the sole responsibility of the user to ensure the area is free of
obstrucons and that it is safe to operate the gate.
