Installing Monitored Entrapment Protection Devices
Effective January 12, 2016 A vehicular gate operator or vehicular barrier (arm) operator shall have
provisions for, or be supplied with, at least two independent entrapment protection means as specified
in current UL325 standard Table 31.1. At installation, both entrapment protection devices must be
installed and operational before gate operation is allowed.
USAutomatic control boards utilize Type A (Inherent entrapment protection system) as the first
entrapment protection means identified. This is designed into the control boards for all USAutomatic
operators. The second entrapment identified must be a monitored Type B1 or Type B2 device that is
UL325 2016 listed.
SYSTEM MANUFACTURED AFTER JAN. 12, 2016 WILL NOT OPERATE WITHOUT 1 OF THE 2
FOLLOWING TYPES OF MONITORED ENTRAPMENT PROTECTION DEVICES CONNECTED
AND OPERATIONAL.
When the installation requires more than 1 monitored contact edge or 1 monitored photo eye, the
Monitored Entrapment Device Expansion Module must be installed. (USAutomatic Part# 500015)
