APPLICATIONS TECHNICAL SPECIFICATIONS DESCRIPTION OF THE SENSOR SAFETY PRECAUTIONS Shut off all power before attempting any wiring procedures. Maintain a clean & safe environment. Constantly be aware of traffic around the door or gate area. Always suspend traffic through the doorway or gate area when performing testing that may result in unexpected reactions by the door or gate. Always check placement of all wiring and components before powering up to insure that moving parts will not catch any wires and cause damage to equipment.

Operation is subject to the following two conditions:
Changes or modifications not expressly approved by B.E.A., Inc. for compliance could void the users authority to operate the equipment. 1) This device may not cause harmful interference and;
2) This device must accept any interference received including interference that may cause undesired operations.
(FCC ID: G9B-MATRIX)
(IC: 4680A-MATRIX) A . CABLE SPECIFICATIONS FOR LOOP AND FEEDER 16 AWG (1.5mm) cross section area ;
Multi-strand cable ;
Insulation material : PVC or Silicone ;
For the feeder cable, the wire must be twisted at least 15 times per yard for each cable. Feeder for long runs used for foil screened cable is recommended (earth at equipment end only) The feeder cable must be firmly fixed to avoid any false detection (max length: 330 feet (100 m)). Waterproof cable junction box is required. B. LOOP GEOMETRY L Ea Eb When two adjacent loops are connected to a dual channel sensor, it is possible for these loops to share a common slot, if so required. As the channels are multiplexed, no interference will occur. Avoid large loops or long feeder [max 330 feet (100 m)], or else the sensitivity will be affected. C. DETERMINATION OF THE NUMBER OF LOOP TURNS Measure the length (L) and width (Ea) of one loop. Multiply these numbers together to determine the loop surface area. See above drawing. For example, if L=10 ft, Ea= 3 ft, then the area = 30 ft2; 4 loop turns are recommended. or if L=2m, Ea=1m, then the area = 2 m2 ; 4 loop turns are recommended. Recommended values for the turns:
Area Number of turns
<32 ft
<3 m 32 54 ft 3 5 m 65 108 ft 6 10 m 4 3 2 D. SLOT DEPTH

WARNING:
For conformity reasons, in any installation, the loop surface multiplied by the number of turns should not exceed 215 (for square feet); 20 (for square meters) Ground level Loop sealant 75.1046 V3 July 2005 [Rev. 7/21/2005]

Page 3 of 6 DIPSWITCH SETTINGS A 10 position dip switch is located on the front of the Matrix single detector. Dip switch 3, 5, 6, 7, and 8 configure the relay, while dip switch 9 controls the duration of the pulse when the Matrix is configured for pulse operation, (as opposed to presence). Configurations are as follows:
Dip Switch 3:
OFF= FAIL-SECURE MODE Relay is NOT energized when power is applied. Relay is energized upon detection only. In this mode, the N.O. circuit is open, and the N.C. circuit is closed. Thus, if a closed circuit is required upon detection, one must use the N.O. and COM terminals since they would close upon detection. When the Matrix is NOT powered, it is in the same state as it would be for non-detection. ON = FAIL-SAFE MODE Relay is energized as soon as power is applied, and de-energizes upon detection or power loss. In this mode, upon powering the detector, the N.O. circuit becomes closed, and the N.C. circuit becomes open. Thus, if a closed circuit is required upon detection, one must use the N.C. and COM terminals, since they would now be OPEN during non-detection, and would close upon detection. When the Matrix is NOT powered, it is in the same state as it would be for detection. Detection Status No Detection Detection Same Upon Power Loss Fail-Secure Mode (Active Mode)
(Relay is not energized upon power-on) Dipswitch 3 OFF The COM and N.O. terminals are OPEN. COM and N.C. terminals are CLOSED. The relay is de-energized. The COM and N.O. terminals are CLOSED. COM and N.C. terminals are OPEN. The relay is energized. The COM and N.O. terminals are OPEN. COM and N.C. terminals are CLOSED The relay is de-energized. Fail-Safe Mode (Passive Mode)
(Relay becomes energized upon power-on) Dipswitch 3 ON The COM and N.O. terminals are CLOSED. COM and N.C. terminals are OPEN. The relay is energized. The COM and N.O. terminals are OPEN. COM and N.C. terminals are CLOSED. The relay is de-energized. The COM and N.O. terminals are OPEN. COM and N.C. terminals are CLOSED. The relay is de-energized. Same DIPSWITCH SETTINGS III. DIP SWITCHES After each dip switch change the sensor launches a learning process. Dip Switch #1 Frequency Adjustments of Loop A (see ADJUSTMENTS on the next page) Dip Switch #2 Frequency Adjustments of Loop A (with single loop) or Loop B (with dual loops) Dip Switch #3 Relay configuration : active (fail-secure) or passive (fail-safe_ (see above) Dip Switch #4 Automatic Sensitivity Boost (ASB option) [recommended for improved truck detection] :
During a detection, the sensitivity increases automatically to 8 times the preset sensitivity given by the sensitivity potentiometer adjustment. It is limited to the maximum sensitivity
(Df = 0.005%). It goes back to the preset value after detection stops. Dip Switch #5 Relay A function : presence or pulse (not used with dual loop in combined mode) Dip Switch #6 Relay A Pulse type : entry or exit (used only at pulse function) or Relay B mode (with dual loop in combined mode) (see drawing on next page) Non-Directional :
Relay B provides a pulse according to the dip switches #7 and #8 setting. Directional AB :
Relay B provides a pulse only if loop A is detecting before loop B. The logic detection takes place according to dip switches #7 and #8. Warning : During the detection, the 2 loops have to detect simultaneously for a short period to be able to determine the movement direction. During loop installation make sure the 2 loops are close enough to each other to ensure a common detection (typical 3 feet). Dip Switch #7 Relay B function : presence or pulse Or loop selection for relay B pulse : pulse on Loop B or pulse on Loop A (used with dual loop in combined mode) Dip Switch #8 Relay B Pulse type : entry or exit (used only at pulse function) Dip Switch #9 Pulse duration for both relays (used only at pulse function): 100 ms or 500 ms Dip Switch #10 Dual loop mode : independent or combined AB (not used with single loop) 75.1046 V3 July 2005 [Rev. 7/21/2005]

the value of the oscillation frequency measurement or an error message on power ON. Normally, the red LED stays ON as long as the loop is in a state of detection. On POWER ON, the sensor measures the oscillation frequency of each loop. The result of this measurement is displayed using the corresponding red LED. The number of flashes indicates the tens value of the frequency. For example 4 short flashes correspond to a frequency between 40 kHz and 49 kHz. After this message the LED goes back to normal display. If the loop oscillation frequency falls outside the limits (20 kHz to 130 kHz) the red LED displays an error message and the sensor activates the corresponding relay. The blinking frequency shows the type of error according to the next table. The sensor will stay in error mode until the error is cleared and the frequency goes to the right range. Remark : The sensor launches automatically a learning process if the oscillation frequency varies more than 10%
in comparison with the measurement value. Loop frequency error LED display Oscillation frequency too LOW or loop opened Oscillation frequency too HIGH Loop shorted or no oscillation LED blinking at 1Hz LED blinking faster at 2 Hz LED blinking slower at 0.5 Hz 75.1046 V3 July 2005 [Rev. 7/21/2005]
Page 5 of 6 TROUBLE -
SHOOTING SYMPTOM The loop detector will not work. The green LED is off. The loop detector will not work. The red LED is flashing slowly
(0.5 Hz). The loop detector will not work. The red LED blinks at either 1Hz or 2Hz. The loop LED is detecting properly but the contact is not made. Dip switches 5 to 8 are not responding properly. PROBABLE CAUSE There is no power supply to the loop detector. The corresponding loop is shorted. The frequency of oscillation falls outside the allowed range. Bad connection of the relay contacts. Their function varies according to dip switch #10 setting. CORRECTIVE ACTION Check power supply. Check the loop cable. Adjust frequency with dip switches or change loop turns. Check relay connections. Check the appropriate loop mode required and adjust dip switch #10.
