DynaLock 6275 Series Pushbutton, 3/8” Dia. Stainless Steel, 1-60 Sec. PTD, SPDT Form “Z”

PTD means push-to-delay: press the button and the output stays transferred for an adjustable interval anywhere from 1 to 60 seconds before it resets on its own. That is what lets a single press release a maglock long enough for someone to get through the door without anyone holding the button. Set the delay to match how long the opening needs to stay unlocked.

It is an SPDT Form "Z" arrangement, so you get one common with both a normally open and a normally closed contact on a single pole. The N.C. side can break power to a magnetic lock while the N.O. side closes to the access control panel or alarm shunt, but because it is one set of transfer contacts both functions switch together off the same timed press. If you need two electrically independent circuits, you need a two-pole configuration from elsewhere in the 6200 Series rather than this Form "Z" model.

Only if you order it with the narrow plate option, which is 1-3/4 inches wide and sized for narrow stiles and mullions. The standard plate is the wider single-gang size. On a glass storefront or a narrow aluminum frame, specify the narrow plate; on a standard gang box in drywall, the standard plate covers the opening better.

Three choices, each independent, and all eight combinations are orderable: anti-tamper switch yes or no, bi-color red/green LED (12/24 VDC) yes or no, and narrow 1-3/4 inch plate yes or no. Everything else is fixed, the 3/8 inch diameter stainless steel button in red, brushed stainless steel US32D plate, and the 1 to 60 second push-to-delay SPDT Form "Z" switching.

A momentary switch only transfers while a finger is on it, so the lock re-secures the instant the button is let go, fine where a panel takes the input and runs its own unlock timer. The 6275 does the timing itself, 1 to 60 seconds adjustable, so it suits a standalone maglock with no panel between the button and the lock. If you want a plain momentary instead, the Securitron PB3 Series push buttons or the RCI 950 Series momentary push plate cover that role, and for a state that stays latched until reset there are maintained versions such as the RCI 908 Series exit button.

A 3/8 inch diameter button is a small, deliberate-press actuator, good for controlled areas where you do not want accidental releases. For a public egress or accessible route where people need a large, obvious target, a big plate or palm-style actuator is the better pick, such as the RCI 950 Series round push plate with the handicap symbol, or a large illuminated emergency release like the Securitron EEB. Where the opening needs a clearly marked emergency release rather than a discreet button, that is also the direction to go.

The DynaLock 6275 pushbutton can be ordered with a bi-color red/green LED running on 12/24 VDC, which gives you status indication right at the button. If you want a different approach to lighting, the Securitron PB4L uses an illuminated halo around a stainless push button, and the Securitron PB5 is a medium round illuminated push button. All three put a visible indicator at the release point; the 6275 does it with a discrete bi-color LED in the plate, while the PB4L rings the button itself with light.

The DynaLock 6275 is built around a 1-60 second pushbutton time delay with an SPDT Form Z contact, so you are paying for timing you would not use on a plain momentary release. For a straightforward momentary button, the Securitron PB3 series push buttons or the Trine 342 narrow style electric door switch cover that job, and the RCI 950 series round push plate is a momentary switch in satin stainless with a handicap symbol if the opening also needs an accessibility marking.

They are not the same device. The DynaLock 6275 is a 3/8 inch diameter stainless steel pushbutton used as a request-to-exit control, with a 1-60 second time delay and an SPDT Form Z contact. The Securitron EEB is an emergency exit push button with interchangeable LED lenses, and the ACSI 1320-1-MOM-ER is a pushbutton switch marked Emergency Release. Those emergency-marked devices are intended for a labeled emergency release point, so substituting one for a normal daily-use REX button changes the signage and the intent of the opening.

The DynaLock 6275 releases for a field-set interval of 1 to 60 seconds and then restores, so it is not the part for a latched unlock. For maintained operation, look at the RCI 908 series electronic exit button with red EXIT text and maintained operation, the RCI 919 series rotary release button with maintained operation in satin aluminum, or the RCI 909 series flush mount rocker, which is offered in a momentary version rated 250VAC 10A.

It adds a separate switch that signals if the plate is removed from the wall, so the panel sees an attempt to get behind the device and jumper the release contacts. Worth ordering on exterior-facing or public-side locations and on anything an auditor will look at; on a back-of-house door inside a secured space it usually is not needed.

The DynaLock 6275 is a pushbutton anyone at the door can press; the restriction it offers is an optional anti-tamper switch and a narrow 1-3/4 inch wide plate option for tight stiles. If access to the release itself has to be restricted to key holders, a keyswitch is the correct device instead, such as the ACSI 1310-1 mortise keyswitch from the 1300 series.

The DynaLock 6275 itself can be ordered on a narrow plate 1-3/4 inches wide, which is the usual fit for a glass front stile, in brushed stainless steel US32D. If you want an alternative from another maker in the same narrow format, the Trine 342 is a narrow style electric door switch.

Standard finish is brushed stainless steel US32D, which is the common satin stainless used across commercial door hardware and matches the satin stainless plates on most existing request-to-exit stations, for example the RCI 950 Series round push plate in satin stainless. The button itself is red as standard, so if your other stations use a green or clear button the color will read differently even though the plate matches.

It is a commercial device, part of DynaLock's 6200 Series electronic access control line, built for request-to-exit duty on commercial openings with a stainless steel button and stainless plate. It is not a residential doorbell-type switch.
