PRECAUTIONS

• Only trained and qualified personnel are recommended to install and set up the sensor.
• Always test the proper operation of the installation before leaving the premises.
• The warranty is invalid if unauthorized repairs are made or attempted by unauthorized personnel.

INSTALLATION

TIPS

• Single-gang or double-gang electrical boxes (ideally, non-metallic) may be used.
• Single gang electrical boxes are recommended for a 4.75” square version.
• The set screws are 4/40 × 1/2” Allen head screws, adjusted with a 3/32 Allen wrench (supplied).
• Mounting screws are #6-32 × 1/2” Phillips head screws.

APPLICATIONS

NOTE: Do not install the sensor within the swing path of the door.

1. Install the electrical box.
2. Remove the two (2) set screws.
3. Disassemble (i.e. slide up and pull out) the faceplate assembly from the mounting ring.
4. Temporarily mount the mounting ring to the electrical box. Pay attention to “THIS END UP”.
5. Mark four (4) hole locations for installing the mounting ring.
6. Remove the mounting ring from the electrical box.
7. Install four (4) wall anchors.
8. Mount (i.e. hand-tighten) the mounting ring to both the electrical box and the wall.
9. Remove the back of the NEMA 4 enclosure.
10. Sections 2 (WIRING) and 3 (SETTINGS & ADJUSTMENTS) must be completed prior to continuing installation (Section 4).

WIRING

IMPORTANT WIRING NOTES :

• Always use a BEA-provided isolation module (polarity-sensitive) for powering each MS21.
• Red must be connected to power (+) and black connected to power (-).
• It is recommended that 300 V, low-voltage cabling, shielded wire be used during installation.
• It is recommended that the MS21 cabling have a distance of 6 inches around power lines 120 VAC/VDC or higher.
• If using a wire harness with more than 5 conductors, all extra conductors must be wired at both ends to Earth Ground.
• It will take approximately 10 seconds to complete the initialization sequence once powered.
• Wire-nut harness wires and isolation module wires together and then connect the isolation module wires to the door control using the chart or visual representation below.
• NOTE: From isolation module to ACT, use either green (NO) OR yellow (NC).

SETTINGS & ADJUSTMENTS

• (A)SENSING ZONE – potentiometer
• COUNTERCLOCKWISE – decrease (0’’ minimum)
• CLOCKWISE – increase (4’’ maximum)1
• (B)AUDIBLE ALERT – DIP-switch 1 (left)
• ON – audible alert pulsed for 0.5 seconds during detection
• OFF – audible alert off
• (C)LED – DIP-switch 2 (right)
• ON – LED on at rest, pulsed off for 0.5 seconds during detection
• OFF – LED off at rest, pulsed on for 0.5 seconds during detection
• NOTES: Maximum Sensing Zone will vary depending on size (area), orientation, and speed of object as well as environmental conditions.

FINAL INSTALLATION

1. Reinstall the back of the NEMA 4 enclosure.
2. Reassemble (i.e. align, push in, and slide down) the faceplate assembly to the mounting ring.
3. Reinstall the two (2) set screws.
4. Test the installation functionality and performance.

CAUTION:
When installing near unprotected and/or uninsulated circuits, additional electrical isolation may be needed. The shrink tubing over the printed wiring board (provided by BEA) is rated minimum 150V, VW-1, and 80 °C. This information may be taken into account to define whether additional isolation is required.

FUNCTIONALITY

ACTIVATION| Activation signal held until sensing zone is cleared (or relearned). Audible Alert (if enabled) will pulse for 0.5 seconds at initial detection.
---|---
REJECTION| An object must be within the sensing zone for at least 130 milliseconds for detection to occur (i.e. parallel traffic rejection).
TRACKING| Reduced unwanted detections by allowing small variations in baseline capacitance (e.g. temperature/humidity changes). If a stationary object remains within the sensing zone for more than 5 seconds, a new capacitive zone will be learned and normal operation will resume (e.g. chewing gum stuck to the faceplate).

TROUBLESHOOTING

Sensor erratically detecting or falsely activating|  | Not properly grounded| | Verify continuity between sensor ground and earth ground.

See Application Note for details.

---|---|---|---|---
Unstable power supply| Ensure the BEA isolation module (polarity-sensitive) is being used with each MS21.
Electrical noise within the sensing zone| Reduce sensing zone (potentiometer counterclockwise).
Non-stationary objects within the detection zone| Clear a 10” zone around the detection field.
Sensor not detecting| The sensing zone is set too low| Increase sensing zone (potentiometer clockwise).
No power| Verify power supply and connection.

BEA, INC. INSTALLATION/SERVICE COMPLIANCE EXPECTATIONS

• BEA, Inc., the sensor manufacturer, cannot be held responsible for incorrect installations or inappropriate adjustments of the sensor/device; therefore, BEA, Inc. does not guarantee any use of the sensor outside of its intended purpose.
• BEA, Inc. strongly recommends that installation and service technicians be ADM-certified ed for pedestrian doors, IDA-certified for doors/gates, and factory-trained for the type of door/gate system.
• Installers and service personnel are responsible for executing a risk assessment following each installation/service performed, ensuring that the sensor system installation is compliant with local, national, and international regulations, codes, and standards.
• Once installation or service work is complete, a safety inspection of the door/gate shall be performed per the door/gate manufacturer recommendations and/or per ADM/ANSI/DASMA guidelines (where applicable) for best industry practices. Safety inspections must be performed during each service call – examples of these safety inspections can be found on an ADM safety information label (e.g. ANSI/DASMA 102, ANSI/DASMA 107).
• Verify that all appropriate industry signage and warning labels are in place.
