SECONDARY OBSTRUCTION SENSING DEVICES
Another sensing device (Either a contact or a non-contact system) must be
installed and connected to this unit to increase protection against entrapment
per U/L requirements.
NOTE:
All safety device contacts must be
NORMALLY OPEN.
NOTE:
24 VAC power is available at marked terminals for devices that may
require it (i.e., photo eyes, wireless edges, etc).
CONTACT SENSOR INSTALLATION:
NOTE:
Wireless sensors must be installed so there is no signal interference.
NOTE:
All hard wiring to safety edges must be installed so there is no threat
of mechanical damage to wiring between components, when the gate is
moving.
1. Install electric edge sensors in locations shown below.

A separate pedestrian gate must be installed if there is no other entry
access but the vehicular gate.
