DynaLock NTB Series No-Touch Buttons
DynaLock NTB Series No-Touch Buttons feature a touchless infrared
sensing switch mounted on a stainless steel faceplate, activated by
waving one’s hand and are designed for control of electromagnetic
and electromechanical locks, or auto door operators. The default
sensor range of approximately 4” may be adjusted for greater or lesser
sensitivity/range. Activation/relock time may be adjusted for up to 9
seconds of duration and a ring LED provides visual status indication in
both blue and green.
All NTB Series models operate on 12 or 24VDC continuous input power
and include 7” color-coded wire lead terminations.

DynaLock NTB1 – Frequently Asked Questions
1) What voltage do the DynaLock NTB no-touch buttons need?
All NTB Series models run on 12 or 24VDC continuous input power, so they tie into the same DC supply already feeding a maglock or electric strike. They come with 7 inch color-coded wire leads for terminating in the box. Note it is continuous DC input, not VAC, so a transformer output alone won't drive them.
2) How close does your hand have to get to a DynaLock NTB touchless switch to trigger it?
Default sensing range on the infrared switch is about 4 inches, and it can be adjusted up or down for greater or lesser sensitivity and range. So if it's mounted where people brush past it, dial the range back; if it's behind a thicker faceplate location or gloved-hand traffic, open it up.
3) Which NTB model do I order, 1-gang or 2-gang, and do I need the EXIT marking?
Four choices: NTB1 is 1-gang with a plain faceplate, NTB1E is 1-gang silkscreened "EXIT", NTB2 is 2-gang plain, and NTB2E is 2-gang silkscreened "EXIT". Pick the gang size to match the existing box or the plate opening you're covering, and the EXIT version where the button is serving as the marked egress release at the door.
4) Can a no-touch button release a maglock and also trigger an automatic door operator?
Yes. The NTB Series is built for control of electromagnetic and electromechanical locks as well as auto door operators, which is why it's common on restroom and lobby openings where the same wave has to drop the lock and start the operator.
5) Is there a wireless option instead of running wire to a DynaLock NTB no-touch button?
The DynaLock NTB Series buttons are hardwired devices - every NTB model runs on 12 or 24VDC continuous input power and terminates in 7 inch color-coded wire leads, so the faceplate needs a wire path back to the lock or operator. If the opening cannot take that wiring, the LCN 8310-3803 is a 3V wireless conversion kit for jamb mount touchless actuators, which moves the actuation signal over a wireless link instead of a wire run. The NTB gives you the infrared sensing switch on a stainless steel faceplate with adjustable range and adjustable activation/relock time up to 9 seconds; the LCN part is a conversion kit for an actuator rather than a complete touchless switch.
6) How long does the DynaLock NTB hold the lock released after someone waves at it?
Activation/relock timing is adjustable on the unit for up to 9 seconds of duration. That's set in the field, so you can give an ADA-height opening enough time to swing and clear without adding a separate timer relay.
7) Is the faceplate on the DynaLock NTB durable enough for a public corridor or a hospital?
The infrared sensing switch is mounted on a stainless steel faceplate, and the NTB Series is a commercial-rated product. Because it's touchless there's no mechanical plunger or microswitch to wear out from the traffic, which is the usual failure point on a pushbutton in a high-use public opening.
8) I want a touchless actuator on the jamb instead of in a gang box, and I don't want to run wire. What else is there?
The NTB Series is a hardwired gang-box device on 12 or 24VDC with 7 inch leads, so it needs a box and a wire run. Where you're mounting on a jamb and can't pull wire, LCN offers the 8310-3803 3V wireless conversion kit for jamb mount touchless actuators, which is the wireless route on that kind of opening.
9) Will a request-to-exit kit do the same job as a DynaLock NTB no-touch button?
No - they sit at different points in the circuit. The DynaLock NTB is a wall-mounted touchless infrared switch on a stainless steel faceplate that a person activates to release an electromagnetic lock, electromechanical lock, or auto door operator. A request-to-exit kit is a switch built into the door hardware itself and triggered by using that hardware: the Command Access REX-KIT-ML is a field installable request to exit kit for ML1-Series mortise locks, and the Command Access CRSREXKIT-ED is a field installable request to exit kit with an SPDT switch for Cal Royal 22/98 and Sargent 80 Series exit devices. Many jobs use both - the REX kit signals that the door was used from the inside, while the NTB is the deliberate release actuator.
10) What should I use if I need a push-to-exit switch that people physically press rather than wave at?
The DynaLock NTB Series is touchless only - activation comes from waving a hand in front of an infrared sensor with a default range of about 4 inches, and a ring LED shows blue or green status. For a contact push button application, the Dortronics 5000 Series push buttons and 6500 Series pull stations are the mechanical equivalent family, and the Dortronics 6510/COV anti-tamper alarm cover fits those 6500 Series pull stations and 5000 Series push buttons where the station needs protection from casual use. Touchless units are chosen for hygiene and for handicap-accessible openings; mechanical stations are chosen where a deliberate physical action is wanted.
11) Does the DynaLock NTB button come with a power supply, or do I need one?
The NTB Series buttons are switches only - all NTB models require 12 or 24VDC continuous input power supplied to them, so the power source is a separate line item. The Adams Rite 4605 is a transformer taking 115 VAC to 12/24 VAC with a 40 volt-amp output, and the Locknetics RDB4 is a 4-output relay distribution board for splitting a controlled output to multiple devices. Note that the NTB calls for DC input, so specify a DC source for the button itself.
12) Can a DynaLock NTB no-touch button be used on an all-glass storefront door?
The NTB Series mounts to a 1-gang or 2-gang box behind a stainless steel faceplate, so it goes in a wall or jamb rather than on the glass leaf itself. For hardware that mounts to a frameless glass door, Securitron offers a Glass Door Series accessory line rated Grade 2, and the Securitron SAM surface mount kit accessories and SWB SAM wood bracket are the surface and wood-frame mounting parts for that family. The NTB remains the touchless actuator on the wall; the glass door accessories address attaching the lock hardware to the leaf.
13) Does the NTB button show whether the door is locked or released?
A ring LED around the sensor gives visual status in both blue and green, so a user standing at the door can see the state change when they wave rather than guessing and pushing on a still-locked door.
14) Can I protect a no-touch button from nuisance activation or tampering in a school corridor?
The NTB itself handles casual false triggering through its adjustable sensor range, which can be reduced below the roughly 4 inch default so only a deliberate wave close to the plate registers. It is not a protected-cover device. Where you need a physical tamper cover on a release, Dortronics offers the 6510/COV anti-tamper alarm cover, though that is built for 6500 Series pull stations and 5000 Series push buttons rather than the NTB plate.
15) I need an audible alert at the door, not just a touchless release - what pairs with or replaces the NTB for that?
The DynaLock NTB Series signals status visually, with a ring LED that indicates in both blue and green; there is no sounder in the button. For audible annunciation at the opening, the Adams Rite 29-0218 is a piezo electric horn with multi-voltage compatibility, and the RCI 914 Series is a delayed egress sounder with field-selectable volume output up to 102dB. These are additions rather than substitutes - the horn or sounder annunciates, while the NTB remains the touchless actuation device.
16) Is a DynaLock NTB button suitable for a wet or high-dust exterior opening?
The NTB Series is a commercial infrared sensing switch on a stainless steel faceplate with an adjustable sensor range, specified for control of electromagnetic and electromechanical locks and auto door operators. For protecting access control hardware in wet or dusty conditions, the HES 1000-102 is a Grade 1 rain guard for 1006 Series electric strikes in rain or high dust areas, and the Dortronics 6510/COV is an anti-tamper alarm cover for 6500 Series pull stations and 5000 Series push buttons. Match the protective accessory to the device it is listed for rather than assuming it fits the NTB faceplate.
