Photon infrared gate safety beams have been designed to
provide an integral element of safety to an automated system
while at the same time affording the installer considerable
freedom during the installation process. The transmitter is
completely wireless – being powered via two AA Alkaline
batteries – obviating the need for tunnelling and digging and
subsequent defacement of one’s driveway for the purpose of
running cables. Not only does this arrangement allow for
significant flexibility and fewer restrictions when it comes to
mounting the beams, but it dramatically reduces material and
labour costs.

Refer to the relevant product documentation for further
information about Intruder-detection Alarm functionality.
It is of paramount importance that the beams are
mounted on surfaces that are reasonably parallel to
one another. Small differences in the angle between
the opposing parallel surfaces can lead to large
offsets between the transmitter and the receiver
alignment of the beams - the greater the distance the
infrared beam travels between the transmitter and
the receiver, the larger the offset

For ease of alignment, an onboard buzzer has been
provided on the receiver, that can be activated by
placing the Photon receiver unit in Installer Mode,
described in the relevant section

Please take special note of critical aspects that
MUST be adhered to in order to prevent injury
In addition, Photon beams are compatible with the unique
Intruder-detection Alarm functionality inherent in some of
CENTURION’s gate operators. These operators allow the
Photon beams to act as sophisticated perimeter security
devices by activating an alarm on the operator’s controller, or
a third-party alarm system, whenever the beams have been
obstructed or remain obstructed for a predefined period of
time.

Anything not expressly specified in these instructions is

When connected to an automated system such as a gate
motor or garage door operator, the Photon beams aid in
preventing personal injury, and/or property damage due to
crushing, when used in a closing beam configuration.
When used in an opening beam configuration, the Photon
beams dramatically reduce the hazardous actions associated
with a gate that is opening; such as dragging or shearing.
The operation of the Photon beams relies upon the infrared
beam being interrupted by a person or object, and notifying a
device connected to its fail-safe contact, of the interruption.

CENTURION does not accept any liability caused by
improper use of the product, or for use other than that

The beam lenses MUST be fitted during the alignment

covers are fitted before beginning alignment

Installer Mode
Installer Mode is a unique feature that facilitates the
alignment of the beams by providing audible feedback via the
receiver’s onboard buzzer.
1.
To enter Installer Mode, press and hold the pushbutton
on the receiver for a period of one second. The buzzer
will emit two beeps to indicate the transition into
Installer Mode
Once in Installer Mode, the LED will illuminate
permanently, while the IR beam signal is not being
received by the receiver.
2.
Next, proceed with the alignment of the beams, noting
the behaviour of the receiver; as soon as the beams are
suitably aligned, the LED will switch off and the buzzer
will emit a continuous 4KHz tone.
The transmitter will remain in Installer Mode for a
period of 120 seconds, but an early exit may be
invoked by momentarily pressing the pushbutton.

Open Collector Mode
In sites where current consumption is a factor, for e.g. solarpowered installations, the onboard relay can be disabled by
selecting Open Collector Mode. This is accomplished by
moving the jumper on the receiver from pins 2 and 3 to pins
1 and 2. The open collector output is then available on the
normally-closed terminal, and will switch down to ground.
Indicators
The receiver has been fitted with a red LED for feedback
and diagnostic purposes.
10. Repeat the same
mounting procedure
when mounting the
transmitter unit.

The red LED will flash five times on power-up, to
indicate the unit is powering up correctly.

In Normal Mode of Operation, the red LED will flash
briefly, once every second, while the IR beam signal
is not detected (i.e. While the IR beam is
obstructed).

In Installer Mode, the red LED will remain on, while
the IR beam signal is not detected (i.e. While the IR
beam is obstructed).

The red LED will remain off in both modes, if the
beam signal is detected

Wiring route
11. Break out the
relevant knockouts
and route the
cables through the
cable cut-out as
shown in the
illustration,
providing
12V - 24V AC or
12V - 30V DC to the
receiver.
In addition, both the receiver and transmitter modules have
been fitted with onboard buzzers, which provide the
following feedback:

12. The receiver’s relay
can then be
connected to the
input of an external
device using either
the normally-open
or normally-closed
contact shown in
the wiring diagram.
13. Test the operation of
the Photon infrared
beams by passing
an object such as
your hand through
the beam; there
should be an audible
‘click’ to indicate
that the internal
relay is being deenergised. If the
beams have been
connected to an
automated system,
the operator should
immediately halt
movement when the
beams are
obstructed.
If Open Collector is used,
there will not be a “click”

The buzzer on the transmitter PCB will emit an
alarm tone when the batteries are nearing the end
of their functional life. Should the user not have
replacement batteries at his disposal at the time of
notification, the buzzer can be disabled for a period
of 24 hours by momentarily pressing the pushbutton

The receiver buzzer will emit a continuous 4KHz
tone when alignment is obtained ONLY if Installer
Mode is enabled.
