DynaLock 6221 Series Palm Switch Buttons, Alternate-Action DPDT, “EXIT” Faceplate Signage

Alternate-action means the 6221 palm switch latches: press once and the contacts change state and stay there, press again to return. DPDT gives you two independent sets of changeover contacts, so you can drop a maglock and signal an alarm panel or monitoring point off the same press. Use it where the door needs to stay unlocked until someone presses again, for example a receptionist releasing a lobby door for a delivery window. If you want the door to relock by itself after a press, you want a momentary switch instead, such as the RCI 950 Series round push plate or the Securitron PB3.

Both are available. The standard faceplate mounts on a single gang, and there is a two-gang faceplate option measuring 4-9/16 inches wide if you want more plate real estate. There is also a narrow plate option at 1-3/4 inches wide for mullions and narrow stile frames where a standard plate will not sit flat. One thing to watch: the audible sounder option requires the two-gang faceplate, so if you need the buzzer you cannot use the narrow or standard single plate.

Yes, the 6221 is offered with a narrow plate 1-3/4 inches wide, which is what you want on an aluminum mullion or a narrow frame. Finish is brushed stainless steel US32D, so it blends with typical storefront hardware. If the mullion is even tighter than that, a narrow-style switch like the Trine 342 is the other route to look at.

The DynaLock 6221 is an alternate-action DPDT palm switch with EXIT faceplate signage, meaning one press latches the contacts and the next press releases them. The closest cross-brand equivalent in function and marking is the RCI 908 Series electronic exit button with red EXIT text and maintained operation (RCI-908-RE-MA 32D), which also latches in place rather than returning on release and carries EXIT text on the plate. Both are surface-readable EXIT stations for request-to-exit duty, so an integrator standardizing on maintained EXIT buttons can specify either.

The 6221 is alternate-action, so the contacts stay transferred until the button is pressed again - that is wrong for an opening where the door should only unlock while the button is held or for the moment of the press. For momentary action, look at the ACSI 1320-1-MOM-ER pushbutton switch marked Emergency Release, the RCI 909 Series flush mount momentary rocker switch rated 250VAC 10A, or the RCI 950 Series round push plate with handicap symbol in satin stainless, which is also a momentary switch.

The DynaLock 6221 is a standard request-to-exit palm switch with EXIT faceplate signage and an alternate-action DPDT contact block; it is meant for everyday egress release, not for a dedicated emergency station. Where the specification calls for an emergency release device, the Securitron EEB emergency exit push button with interchangeable LED lenses or the ACSI 1320-1-MOM-ER, which is marked Emergency Release, are the devices built for that role.

No - they are different devices. The DynaLock 6221 is a free-access palm switch with EXIT signage that anyone can press to release the door. The ACSI 1310-1 is a mortise keyswitch from the 1300 Series, which requires a key to operate and mounts into a mortise prep rather than a switch box. Use the keyswitch where the release must be restricted to keyholders, and the 6221 where egress must be available to all occupants.

Standard is red, and green is an option on the 6221. Many integrators run green for free-egress request-to-exit and reserve red for emergency release, so if you are standardizing a building keep the color assignment consistent across openings. The EXIT faceplate legend stays the same either way.

The anti-tamper switch on the 6221 gives you a contact that reports if the plate is removed from the box, so your access control or alarm panel sees an attempt to get at the wiring behind the button. It is worth specifying on exterior-facing or public-corridor locations in schools, healthcare, and multi-family buildings. On a locked back-of-house door in a controlled area it is usually skipped.

Depends on what the opening needs. For a maintained EXIT button similar in function to the latching 6221, the RCI 908 Series with red EXIT text and maintained operation is the closest peer. For momentary release, look at the Securitron PB3 or the RCI 950 Series round push plate with handicap symbol, which suits ADA-style actuator locations. For illuminated buttons, the Securitron PB4L with an illuminated halo or the PB5 medium round illuminated button. For an emergency release device rather than a routine exit control, the Securitron EEB or the ACSI 1320-1-MOM-ER, which is marked Emergency Release. Keyed control instead of a button points to the ACSI 1310-1 mortise keyswitch.

Functionally they line up: the RCI 908 Series is a maintained-operation button with red EXIT text, and the 6221 is an alternate-action latching switch with EXIT faceplate signage, so the switching behavior and the legend match. Physically, plate size and box prep are what decide it, and the 6221 is offered in narrow 1-3/4 inch, standard, and two-gang 4-9/16 inch plates, so measure the existing cutout and pick the plate that covers it.

The 6221 is built around an alternate-action DPDT switch with option add-ons such as an anti-tamper switch, bi-color red/green LED for 12/24 VDC, and an audible sounder on the two-gang plate. If the opening only needs a plain press-to-release station, the Securitron PB3 Series push button is a basic push button device, and the Trine 342 is a narrow style electric door switch for tight frames. Both cover the switch function without the multi-pole and indicator options.

The DynaLock 6221 handles indication with an optional bi-color red/green LED rated 12/24 VDC mounted in the faceplate alongside the palm button, and an optional audible sounder when the two-gang faceplate is selected. If you want the illumination in the button itself, the Securitron PB4L Series uses an illuminated halo around a stainless push button and the Securitron PB5 Series is a medium round illuminated push button. The DynaLock approach keeps a large palm-operated button with a separate indicator; the Securitron devices light the actuator.

The DynaLock 6221 is offered with a narrow plate 1-3/4 inches wide as well as a two-gang faceplate 4-9/16 inches wide, so the narrow-plate build already addresses tight mullions and frames. If you prefer another manufacturer for that condition, the Trine 342 is a narrow style electric door switch made for the same situation.

The DynaLock 6221 is a palm switch with EXIT faceplate signage and an alternate-action DPDT contact, so its marking reads as an egress release rather than an accessible door actuator. Where the opening needs a handicap-symbol actuator, the RCI 950 Series round push plate carries the handicap symbol and a momentary switch in satin stainless steel, which is the marking and action normally used to trigger an automatic operator.

The DynaLock 6221 ships standard in brushed stainless steel US32D with a red button, with a green button available as an option. The RCI 908 Series electronic exit button is offered in 32D as well, so the two match visually on a wall. The RCI 919 Series rotary release button is finished in satin aluminum and the RCI 909 Series flush mount rocker is beige, both of which will read differently alongside a stainless plate.

The 6221 palm switch is a commercial request-to-exit control, part of DynaLock's 6000 Series REX line, and comes in brushed stainless steel US32D. Palm-size buttons are chosen where people push with a hand rather than a fingertip, so they suit corridors, stairwells, and high-traffic egress points that property managers want consistent across a building.

The DynaLock 6221 uses a large palm-operated button so it can be struck with a hand or forearm. For a maintained release with a smaller actuator, the RCI 919 Series rotary release button offers maintained operation in a satin aluminum finish and is turned rather than palmed, and the RCI 908 Series button gives maintained operation behind a red EXIT marked plate.
