IMPORTANT SAFETY INSTRUCTIONS Specic to Secondary
Means of Protection Against Entrapment
AsspeciedbyUnderwritersLaboratoriesInc.UL325(30A.1.1),automaticgateoperatorsshallhaveprovisions
for, or be supplied with, at least one independent primary and one independent secondary means to protect
against entrapment. GTO gate operators utilize Type A, an inherent entrapment sensing system, as the primary
type of entrapment protection. The GP-SW050 operators have provisions for the connection of Type B1, B2, or
D protection to be used as the secondary type of entrapment protection.
1.Forgateoperatorsutilizinganon-contactsensor(TypeB1)inaccordancewithUL325(51.8.4[h]):
A. Refertothesensormanufacturer’s instructions on the placement of non-contact sensors for each type of
application.
B. Careshallbeexercisedtoreducetheriskofnuisancetripping,suchaswhenavehicletripsthesensor
whilethegateisstillmoving.
C. Oneormorenon-contactsensorsshallbelocatedwheretheriskofentrapmentorobstructionexists,
such as the perimeter reachable by a moving gate or barrier.
2.Forgateoperatorsutilizingacontactsensor(TypeB2)inaccordancewithUL325(51.8.4[i]):
A. Oneormorecontactsensorsshallbelocatedattheleadingedge,trailingedge,andpostmountedboth
insideandoutsideofavehicularswinggatesystem.
B. Ahardwiredcontactsensorshallbelocatedanditswiringarrangedsothatthecommunicationbetween
the sensor and the gate operator is not subjected to mechanical damage.
C. Awirelesscontactsensorsuchasonethattransmitsradiofrequency(RF)signalstothegateoperator

3. For gate operators utilizing an actuating device requiring continuous pressure to maintain opening or
closingmotionofthegate(TypeD)inaccordancewithUL325(51.8.4[e]):

B. Warning signs (see page 6) shall be placed adjacent to the controls.
C. Nootheractivationdeviceshallbeconnected.
