General Description
The AccuGuard HP2 is an active infrared 2-beam safety
system. This modular system consists of a separate
Control Module, two Transmitter Beam Heads with cables
and two Receiver Beam Heads with cables. The beam
heads are available for recess mounting and can be
ordered with surface mount housings (HP2-SURFACE).
When a beam is interrupted, the Control Module signals
the door to open. In the event of a power loss to the
AccuGuard HP2, it will also signal the door to open, thus
providing a failsafe system.

Installation
Mounting (Fig. 2)
1. Mount the Control Module at the desired location in
the operator housing using either the supplied screws
or two-sided tape.
2. Drill 1/2" holes for each beam head at the desired
location in the door frame, sidelight or rail.
NOTE:
Opposing beam heads must be mounted
at equal heights to function properly
.
3. Insert cable through the 1/2" hole and pull cable up to
the control module.
WARNING:
Be careful not to snag the cable on
any sharp edges. Damage to the cable can
cause the device to malfunction.
WARNING:
To avoid beam “cross talking” mount
the Transmitter Beam Heads opposite of each
other.
4. RECESS MOUNT: Push each Beam Head into the 1/2"
holes.
SURFACE MOUNT: Attach the surface mount housing
(with Beam Heads installed) at the desired location
using the supplied screws ensuring the 1/2" holes are
covered.
Wiring (Fig. 3)
1. Connect Beam Head cables to the Control Module
(wiring diagram is printed on housing). Transmitter
cables are blue and Receiver cables are gray.
NOTE:
If only one set of beams is being used,
the L1 Transmitter and Receiver connections
must be used. L2 is empty.
WARNING:
Any excess cable must be fastened
down, clear of any moving parts.
2. Connect the Control Module outputs to the operator
control - select N.O. (normally open) or N.C. (normally
closed)
via the slide switch on side of the Control
Module.
N.O. =
Contacts close when beams are broken or when
power to the Control Module is interrupted (failsafe).
N.C. =
Contacts close when beams are not broken.
3. Connect power supply to the Control Module: 12-24 V
AC or DC.
