DynaLock 6851 Series Pushplates, Recessed Narrow, Alternate Action SPDT

No, it is not momentary. Alternate action means the plate latches: press once and the contacts transfer and stay there, press again and they return. That suits maintained functions like holding a maglock released for a delivery window or putting a door in an unlocked state. SPDT gives you one common with both a normally open and a normally closed contact, so you can wire it to break power to a lock or make a circuit to a controller. If you want the door to release only while the plate is held or momentarily after a press, order a momentary model instead; DynaLock's momentary versions in this family feature all active operation.

No. The 6851 is alternate action, so a press latches the contacts and they stay transferred until someone presses again. It will not self-restore. For press-and-release operation, order a momentary model from the same DynaLock 6700/6800 pushplate family, or use a momentary peer such as the Securitron PB3, the RCI 909 flush mount momentary rocker switch, or the ACSI 1320-1-MOM-ER pushbutton marked Emergency Release. Timed relock comes from a timer or the access control panel, not from the plate itself.

The DynaLock 6851 is a recessed narrow pushplate designed specifically for installation in aluminum store front frames with minimal cut-out preparation. The closest narrow-style alternative from another maker is the Trine 342 narrow style electric door switch, which is also built to the narrow stile profile. The difference is switching: the 6851 is an alternate action SPDT device, so each press latches the contacts to the opposite state rather than returning on release.

The 6851 is cut for narrow aluminum storefront frames, so on a wider hollow metal frame you have room for a full-size device. The RCI 908 Series electronic exit button with red EXIT text is offered in maintained operation, and the RCI 919 Series rotary release button is also a maintained device in satin aluminum. Both latch in the actuated state the way the 6851 alternate action switch does, but in a larger plate format.

The 6851 is an alternate action SPDT device, so it holds its state until pressed again. If the opening needs a press-and-release momentary output, look at the Securitron PB3 Series push buttons, the RCI 950 Series round push plate with handicap symbol, which is a momentary switch in satin stainless steel, or the ACSI 1320-1-MOM-ER pushbutton switch marked Emergency Release. Each of these returns to its normal state when the hand comes off the button.

It comes engraved. The 6700 and 6800 Series plates are machined from solid aluminum with PUSH TO EXIT engraved into the face, so no separate label is needed on the egress side. DynaLock will do special engraving on request through the factory.

The Trine 342 is the closest cross-brand narrow-style electric door switch for the same tight stile situation. If narrow is not a constraint, the Securitron PB3 push button or the RCI 908 Series exit button with red EXIT text are common choices, and the RCI 908 is offered in maintained operation like the alternate action 6851. For a round plate with a handicap symbol instead of PUSH TO EXIT engraving, look at the RCI 950 Series momentary push plate.

It is a recessed plate, so the frame or wall has to be prepped for it. DynaLock kept the prep minimal on the narrow recessed models specifically so they drop into aluminum storefront framing without major fabrication. If you cannot cut the substrate at all, you want a surface mount button rather than this plate.

No. The DynaLock 6851 is a heavy duty egress pushplate engraved PUSH TO EXIT, intended as the routine release device at the door. An emergency release such as the Securitron EEB emergency exit push button with interchangeable LED lenses or the ACSI 1320-1-MOM-ER marked Emergency Release is specified as the break-glass style device for emergency egress and is typically marked and located differently. They are not interchangeable on a drawing that calls out one or the other.

The DynaLock 6851 is a machined solid aluminum plate with engraved PUSH TO EXIT signage and no illumination. If you want a lit device, the Securitron PB4L Series offers an illuminated halo with a stainless push button, and the Securitron PB5 Series is a medium round illuminated push button. Both are round button formats rather than the narrow recessed plate the 6851 uses for storefront stiles.

The 6851 is a push to exit plate anyone can operate. When the release must be restricted to keyholders, a mortise keyswitch such as the ACSI 1310-1 from the 1300 Series is the device to specify instead. It is a cylinder-operated switch rather than a pushplate, so the door prep and the operating method both change.

The DynaLock 6800 Series switching is rated 6 A at 125VAC on the alternate action and other non-PTD configurations, with PTD contacts rated 10 A at 125VAC. The RCI 909 Series flush mount momentary rocker switch is rated 250VAC 10A. If your circuit runs above 125VAC or draws more than the 6851 contacts carry, size the device to the load or switch a relay instead of the door power directly.

The 6851 carries engraved PUSH TO EXIT signage, not an accessibility marking. For an opening that needs the handicap symbol on the actuator, the RCI 950 Series round push plate is supplied with the handicap symbol as a momentary switch in satin stainless steel. Confirm the switching your operator or controller expects, since the 6851 is an alternate action SPDT device and the 950 is momentary.

It is built for that traffic. DynaLock classes the 6800 Series as heavy duty commercial egress control, and the plate is machined from solid aluminum rather than stamped or plastic, which is what holds up in a lobby, school corridor or multi-family entry that sees constant use.

The DynaLock 6851 ships standard in Satin Aluminum US28 and is also offered in Bright Brass US3, Satin Brass US4, Light Bronze US10, Dark Bronze US10B, Medium Bronze US13, Black Satin US19 and Bright Chrome US26, so it can be matched to bronze or black storefront framing as well. Among other makes, the RCI 919 Series rotary release is offered in satin aluminum and the RCI 950 Series round push plate in satin stainless steel, both single-format devices rather than an eight-finish range.
