BEA 10MS31U-B – Frequently Asked Questions

1) What is the BEA MS31 Series microwave touchless actuator used for?
The MS31 Series provides touchless activation for automatic doors. It detects motion using microwave technology to trigger door opening without physical contact. Common applications include commercial entrances, healthcare facilities, and retail storefronts.
2) What door systems is this actuator compatible with?
The MS31 works with most automatic door operators that accept low voltage activation signals. It provides relay output for integration with sliding doors, swing doors, and revolving door systems. Verify your door operator accepts the MS31's output specifications before installation.
3) How do you adjust the detection range on the MS31?
The MS31 features adjustable range controls accessible via potentiometers or DIP switches depending on model. Range typically adjusts from 1 to 8 feet. Turn controls clockwise to increase range, counterclockwise to decrease. Test activation points after adjustments to ensure proper coverage.
4) What is the relay hold time feature?
Relay hold time determines how long the actuator maintains door activation after detecting motion. The MS31 allows adjustment from approximately 1 to 30 seconds. Longer hold times keep doors open for slower-moving pedestrians or high traffic areas.
5) What power requirements does the MS31 have?
Most MS31 units operate on 12-24V DC or AC power depending on model. Power consumption is typically under 5 watts during operation. Check your specific model's voltage requirements and ensure compatible power supply capacity for reliable operation.
6) Are there code requirements for touchless actuators?
ADA guidelines recommend activation zones between 18 inches minimum to 80 inches maximum from door. Local building codes may have specific requirements for activation timing and backup manual operation. Consult local authorities having jurisdiction for compliance requirements.
7) What mounting options are available for the MS31?
The MS31 typically mounts to door headers, side walls, or ceiling locations. Standard mounting brackets support various installation angles. Choose locations that provide clear sight lines to activation zones while avoiding interference from nearby objects or reflective surfaces.
8) How do you install the MS31 actuator?
Mount the actuator in desired location using provided brackets. Connect power and signal wires per wiring diagram. Adjust range and hold time settings for application requirements. Test activation zones and door response before final commissioning. Follow manufacturer installation template for optimal placement.
9) What maintenance does the MS31 require?
Clean the detection lens monthly with soft cloth to remove dust or debris. Check mounting security and wire connections annually. Test activation range and hold time settings periodically. Replace unit if detection becomes inconsistent or range cannot be adjusted properly.
10) What can interfere with microwave actuator performance?
Metal objects, glass surfaces, and other microwave sources can cause interference. Fluorescent lighting and electronic devices may affect sensitivity. Install away from these sources when possible. Adjust sensitivity settings if false activations occur from environmental factors.
11) Are there other BEA actuator models available?
BEA offers multiple actuator technologies including infrared, laser, and combination sensors. Different models provide various detection patterns and environmental ratings. Consider traffic patterns and installation conditions when selecting actuator technology for your application.
12) What detection pattern does the MS31 provide?
The MS31 creates an adjustable elliptical detection zone extending from the sensor. Pattern width and depth vary with range settings and mounting height. Higher mounting typically provides wider coverage areas. Test actual coverage patterns during installation to ensure proper activation zones.
