Introduction

Photon infrared gate safety beams/photocells 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 tunneling 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 labor costs.

• This icon indicates warning, caution, or attention! Please take special note of critical aspects that MUST be adhered to in order to prevent injury.

Operation

When connected to an automated system such as a gate motor or garage door operator, the Photon beams/photocells 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/photocells dramatically reduce the hazardous actions associated with a gate that is opening; such as dragging or shearing. The operation of the Photon beams/photocells 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. In addition, Photon beams/photocells are compatible with the unique Intruder-detection Alarm functionality inherent in some of our gate operators. These operators allow the Photon beams/photocells 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/photocells have been obstructed or remain obstructed for a predefined period of time.

• Refer to the relevant product documentation for further information about Intruder-detection Alarm functionality.

Installation

Site Consideration

1. It is of paramount importance that the beams/photocells 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 in alignment between the transmitter and the receiver -the greater the distance that the infrared beam travels between the transmitter and the receiver, the larger the offset.

2. The transmitter and receiver are typically mounted directly opposite one another, but some leeway is given in the form of a wide beam being cast should absolute alignment not be possible. ! 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. (See points 12 & 13 for installer Mode)

   • Centurion Systems (Pty) Ltd recommends a height of 750mm, but the height of the beam must be tailored to suit the specific requirements of the installation.
     Remove cover and prepare for mounting

3. Lift the receiver’s front cover off as illustrated

4. To expose the mounting holes, remove the PCB from the enclosure by pressing the red  plastic lever located at the top of the enclosure as shown. Store the PCB safely to prevent damage.
   Mounting

5. Mark the mounting position of the Photon receiver for a single or double fastener.

6. For masonry mounting, use a 5mm masonry drill bit. For mounting to steel tubing. Use a 2.3mm steel drill bit.

7. Mount the base of the Photon using the supplied hardware. Ensure that the rubber “O” ring is used to seal the Photon enclosure against insect ingression. For double mounting screws, knock out the thin plastic film- this is recommended to better locate the Photon beams and prevent them from twisting.
   Re-Inserting the PCB

8. Tuck the base of the PCB into the ribs situated at the base of the plastic enclosure. Thereafter swing the PCB into place so that the top lever prevents it from falling out. There should be anaudible “click” to lock the PCB in position. Refer to figure 5.
   Receiver Configuration

9. Pay attention to the jumper switch on the receiver as it allows for different configurations. 1&2 – Open collector mode 2&3 – Relay mode (default)
   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 (NC) terminal and will switch down to the ground.
   Wiring the Receiver

10. The receiver’s relay can be connected to the input of an external device using either the normally open or normally closed contact shown in the wiring diagrams alongside. Refer to wiring diagrams for controller connections

    • The NC connection is used most often in gate automation applications to mitigate the problems with wire breaks.
      Wire Routing

11. Break out the relevant knockouts and route the cables through the cable cut-out as shown in the illustration.
    Indicators
    The receiver has been fitted with a red LED for feedback and diagnostic purposes.

    • The red LED will flash five times on power-up, to indicate that the unit is powering up correctly.
    • In Normal Mode of Operation, the red LED will flash briefly, once every second, while the IR beam/photocell signal is not detected (i.e. while the IR beam/photocel is obstructed).

Beam Alignment

Installer Mode

• Installer Mode is a unique feature that facilitates the alignment of the beams/photocells by providing audible feedback via the receiver’s onboard buzzer. In Installer Mode, the red LED will remain on, while the IR beam/photocel signal is not detected (i.e. while the IRbeam/photocel is obstructed). The red LED will remain off in both modes, if the beam signal is detected/ aligned.
• 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

Turning on Transmitter

Refer to step 3. The transmitter has been fitted with a ‘power up’ jumper. In order to preserve battery life, the unit has been packed with the jumper in the OFF position; to power up the transmitter, simply position the jumper so that it is bridging the ON and COMMON pins as illustrated.

Once in Installer Mode, the red LED will illuminate permanently, while the IR beam signal is not being received by the receiver.

• The beam lenses MUST be fitted on the receiver during the alignment procedure as they serve to focus the infrared beam. Failure to do so may result in an inability to achieve alignment. Refer to figure 11a. Do not screw closed until the beams have been aligned.

1. 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 receiver will remain in Installer Mode for a period of 120 seconds, but an early exit may be invoked by momentarily pressing the pushbutton.
2. Once optimum alignment has been achieved, mark the location of the Photon transmitter on the mounting surface.
3. To prevent damage, switch off the transmitter as shown in figure 9.
4. Mount the transmitter following steps 4-8 above and switch on the transmitter.

Closing

1. Close the units by placing the front cover onto the base as shown in figure 11a. Do not force the cover, rather place it over as illustrated.

2. Insert and fasten the ”shorter” screw provided to close the two enclosures together, follow by inserting the plastic cover provided. (Refer to figure 11b). The installation is now complete.
   Final Testing

3. Test the operation of the Photon infrared beams/photocells by passing an object such as your hand through the beam; there should be an audible ‘click’ toindicate 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 transmitter module has been fitted with an onboard buzzer, which provides the following feedback: 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.
