DynaLock 6755 Series Handicapped Pushplates, Recessed Single Gang, 1-60 Sec. PTD, SPDT Form “Z”

PTD is a built-in pneumatic-style push-to-delay timer: press the plate and the contacts transfer, then hold that state for an adjustable interval anywhere from 1 to 60 seconds before returning. That is what lets one press release a maglock or trigger an operator long enough for someone to clear the opening, with no separate timer module in the enclosure. The timed models also carry a higher contact rating than the rest of the family, 10 A at 125VAC versus 6 A at 125VAC on the non-PTD versions.

Form Z is a single-pole double-throw arrangement, so you get both a normally open and a normally closed contact off the one press. Wire the NC side in series with the maglock power to drop it and use the NO side as a dry contact to the access panel or alarm shunt. Contacts on this timed version are rated 10 A at 125VAC, which covers a transformer or door operator circuit as well as low-voltage lock power.

Depends on how long the lock has to stay released. A momentary plate breaks the circuit only while a hand is on it, which is enough for a strike or a quick release but not for a slow-moving user at an ADA opening. The 6755's 1 to 60 second adjustable timer holds the release after the hand comes off, which is the configuration you want with a maglock or a low-energy operator. Note that DynaLock's momentary models in the 6705 family are the ones with "all active" operation, and they carry the 6 A rating rather than the timed version's 10 A.

The DynaLock 6755 is a recessed single gang model, and DynaLock notes that narrow recessed models in the 6705 and 6805 series are designed for installation in aluminum store front frames with minimal cut-out and preparation. If your stile will not take a single gang cut-out, the Trine 342 is a narrow style electric door switch built for that profile. Confirm the stile face width against the plate before you cut.

The nearest cross-brand equivalent is the RCI 950HP, a 950 Series round push plate with a handicap symbol and a momentary switch in satin stainless steel. Both are handicap-symbol actuators for automatic door and egress control. The difference is form and switching: the DynaLock 6755 is a recessed single gang plate machined from solid aluminum with a blue engraved handicapped symbol, and it carries a 1 to 60 second pneumatic time delay with an SPDT Form Z contact rated 10 A at 125VAC, while the RCI 950HP is a round plate with straight momentary operation. Choose the 6755 when the opening needs the built-in adjustable delay; choose the round RCI plate when the door controller or operator already handles timing.

Machined from solid aluminum, with the handicapped symbol engraved rather than printed or applied as a decal, so it will not wear off under constant use. DynaLock classes the 6705 and 6805 pushplates as heavy duty egress controls for commercial service, which is what you want at a lobby or restroom entry taking hundreds of presses a day.

Where a single gang recess will not work, a round surface plate or a smaller button is the way out. ZenSupply carries the RCI 950 Series round push plate with the handicap symbol as a momentary switch in satin stainless, and the Securitron PB3 and PB5 Series push buttons, the PB5 being a medium round illuminated unit. For a narrow storefront stile where nothing else fits, the Trine 342 is a narrow style electric door switch. None of those carry the 6755's built-in 1 to 60 second timer, so if you need timed release you would be adding a separate timer.

It is not the right part for that. The 6755 is a handicapped egress pushplate with a blue engraved wheelchair symbol, intended as a normal-use request-to-exit or door release. An emergency release needs the marked, often tamper-evident type: ZenSupply carries the Securitron EEB emergency exit push button with interchangeable LED lenses, the ACSI 1320-1-MOM-ER pushbutton marked "Emergency Release", and the RCI 908 Series electronic exit button with red EXIT text. Use one of those where code or the AHJ calls for an emergency release, and keep the 6755 for the accessible entry.

The DynaLock 6755 is a solid aluminum recessed plate with a blue engraved handicapped symbol, offered in Bright Brass US3, Satin Brass US4, Light Bronze US10, Dark Bronze US10B, Medium Bronze US13, Black Satin US19, Bright Chrome US26 and Satin Aluminum US28. For a lit actuator, the Securitron PB4L is an illuminated halo with a stainless push button and the Securitron PB5 is a medium round illuminated push button. Those are round button devices rather than engraved handicap plates, so if the opening needs the accessibility symbol you would keep the 6755 and add separate signage or lighting.

For a plain release button, look at the Securitron PB3 Series push buttons or the RCI 908 Series electronic exit button, which is offered with red EXIT text and maintained operation. The DynaLock 6755 is a heavy duty handicapped pushplate machined from solid aluminum with a blue engraved handicapped symbol and a 1 to 60 second pneumatic time delay, which is what you want when the opening serves an accessible entrance and needs a held output. If the opening is an ordinary staff egress point with no accessibility signage requirement, a button-style device covers it.

The DynaLock 6755 uses an SPDT Form Z contact with a 1 to 60 second pneumatic time delay, so the output is held for an adjustable interval and then drops out on its own. If you need a state that stays until someone changes it, the RCI 919 Series rotary release button is offered with maintained operation in a satin aluminum finish, and the RCI 908 Series electronic exit button is offered with maintained operation as well. A maintained device holds the door unlocked indefinitely, which is a different operating intent than a timed release.

For key control of the opening, the ACSI 1310-1 is a 1300 Series mortise keyswitch. That restricts operation to a keyholder, which is the opposite intent from the DynaLock 6755, a handicapped pushplate meant to be operated by any occupant approaching the door. Many accessible entries carry both: a keyswitch for staff control of the operator and a 6755 plate for public actuation.

A pushplate is for public use by anyone at the door; if release should be restricted to staff, you want a keyswitch instead. ZenSupply carries the ACSI 1310-1 mortise keyswitch from the 1300 Series for that. You can also run both on an opening, keyswitch for staff control and the 6755 handicapped plate for accessible entry, since the 6755's Form Z contacts give you a separate NO and NC set to wire into the same lock circuit.

They are sibling families. DynaLock groups the 6705 and 6805 Series together as heavy duty handicapped pushplates, both machined from solid aluminum with the blue engraved symbol and both offered in multiple switching configurations and finishes. The 6755 is a 6705 Series model, specified as recessed single gang with 1 to 60 second PTD timing and SPDT Form Z contacts. If the drawing calls out an 6805 number, order that number rather than substituting this one.
