  3. For hardwired applications, disconnect power supply and route wiring according to manufacturer specifications using appropriate wire gauge and connections.
  4. Configure immunity mode settings based on environmental conditions including lighting, weather exposure, and potential interference sources.
  5. Connect to wireless transmitters if using wireless integration, following pairing procedures in manufacturer documentation.
  6. Test detection range and sensitivity across the full activation zone, adjusting settings as needed for optimal performance.
  7. Verify LED battery status indicators are functioning and document initial battery installation date for maintenance scheduling.

BEA 10MS51-S – Frequently Asked Questions

1) Which BEA MS51 mounting version do I need for a narrow door jamb versus a wall box?
Four mounting versions cover different spots on the opening. The jamb version, 10MS51-J, is 1.68 in (W) x 4.5 in (H) x 0.98 in (D), narrow enough for a tube frame or door jamb. The single gang 10MS51-S is 2.75 in (W) x 4.5 in (H) x 0.98 in (D) and drops onto a standard single gang box. The double gang 10MS51-D is 4.5 in (W) x 4.5 in (H) x 0.98 in (D). There is also a 6 inch round, 10MS51-R, for surface or bollard style placement. Measure the frame face before you pick the jamb version.
2) Can the BEA MS51 touchless actuator run without pulling wire to it?
Yes. The MS51 is battery powered with three years of operation, so you can mount it on a jamb or wall with no conductor run and no box behind it, which is what makes it usable on retrofits where the wall is already closed. If you do want it powered, it accepts 12 to 24 VAC/VDC or 5 VDC, and it can also feed an operator through a wireless transmitter. LED alerts flag battery status so maintenance can plan the swap.
3) How close does someone have to get to the MS51 actuator for it to trigger the door?
The sensing zone is adjustable from 2 in out to 24 in, so you can set it tight (2 to 4 inches) where you do not want passing traffic firing the door, or open it up near the full 24 inches at an entrance where people arrive with carts or hands full. Hold time is separately adjustable from 1 to 30 seconds, which is the setting that decides how long the operator stays energized after a wave.
4) Will the BEA MS51 actuator hold up mounted outdoors in rain and freezing weather?
Rated NEMA 4 / IP65 and good from -22 deg. F to 158 deg. F, so an exterior jamb or an unheated vestibule is within spec. It also has selectable immunity modes intended to keep rain, water spray, snow and harsh lighting from causing false activations, which is the usual failure on an exterior actuator rather than the enclosure itself.
5) Can I wire the MS51 actuator straight into my existing door operator's activation input?
The output is a 1-Form C solid state relay rated 1 A at 30 VAC/VDC maximum, so it switches a dry activation input on a low voltage operator directly. It is not a power switch: do not run motor or lock current through it. If you are firing an electric strike or maglock, switch a separate relay or the operator's own aux output and keep the MS51 contact on the signal side. A 12 in wire harness comes on the unit, so plan a junction within that reach.
6) What faceplate options come on the BEA MS51 and does the accessibility symbol cost a different part?
Every mounting version comes in four faceplate treatments: hand logo, accessibility logo, plain, and text only. It is one option on the same actuator, not a different device, so the double gang, single gang, jamb and 6 inch round can each be had with any of the four. Facilities standardizing on the blue accessibility symbol at every ADA entrance can order that face across all four mounting styles.
7) Is the MS51 push plate durable enough for a hospital or school corridor where people still slap it?
The faceplate is stainless steel with an ABS center, so the contact face is a wipeable metal that handles disinfectant routines and the abuse a corridor gives it. Nothing on it moves, which is the point in a high traffic opening: there is no plunger or microswitch to wear out the way a mechanical push plate does.
8) Does the BEA MS51 actuator work as a toggle to hold a door open, or only as a momentary wave?
Three detection modes are selectable: motion (bidirectional), toggle, or timed. Motion is the normal wave-to-open. Toggle latches the output on with one wave and off with the next, which is how you hold a door open for a delivery or a move-in without propping it. Timed runs the output for the hold time you set, 1 to 30 seconds. Audible feedback can be set to silent or signal mode, and the LED reads blue in standby, green on activation.
9) How much power does a touchless actuator like the BEA MS51 draw if I hardwire it off the operator's accessory supply?
Current consumption is under 2.8 W on 12 to 24 VAC/VDC or 5 VDC. That is small enough to sit on most low voltage operator accessory taps alongside other devices, but add it against whatever else is on that supply before you commit, since two actuators plus a card reader on one tap is where these budgets go over.
