DynaLock 6921 US26 – Frequently Asked Questions
1) What does alternate action mean on the DynaLock 6921 pushplate, and when would I want it instead of momentary?
Alternate action (A-A) is a maintained switch: press once and the contacts stay transferred, press again and they return. On a mag lock that means the door stays unlocked until someone presses the plate a second time, which is what you want for a door you need to hold released (deliveries, moving day, a propped corridor). If you only want the lock to drop long enough for one person to walk through, choose a momentary (MOM) model in the same 6901 Series instead, or a maintained peer like the RCI 908 Series exit button.
2) Is the DynaLock 6921 switch DPDT, and can it control two separate circuits?
Yes. The 6921 is a double pole, double throw switch, so it gives you two independently switched sets of contacts off the one plate. Typical use is dropping the mag lock on one pole while the second pole signals an alarm shunt, an access panel input, or an auto operator. If you only need one circuit switched, a single pole double throw (SPDT) model in the same series covers it.
3) What is the contact rating on the DynaLock 6901 Series pushplates?
On the 6921 and every other non-PTD model in the series, the contacts are rated 6 A at 125VAC and are UL rated. Only the pneumatic time delay (PTD) versions go higher, at 10 A at 125VAC. Six amps at 125VAC is plenty for switching a mag lock supply or a control input, but if you are switching a heavier AC load directly through the plate, size it against that 6 A figure.
4) What size electrical box does the DynaLock 6921 pushplate need?
It is a double gang plate, so it mounts over a two-gang box or two-gang mud ring. A single-gang rough-in will not take it. If the wall is already roughed in single gang and you cannot change it, look at a smaller-format button instead, such as the Securitron PB3 or the Trine 342 narrow style switch.
5) What is the closest alternative to the DynaLock 6921 pushplate if I need a maintained-action exit switch but not a double gang plate?
The DynaLock 6921 is an alternate action (maintained) double gang pushplate machined from solid aluminum with engraved PUSH TO EXIT lettering. If the opening only has room for a button rather than a double gang plate, the RCI 908 Series electronic exit button with red EXIT text also operates as a maintained switch, and the RCI 919 Series rotary release button is a maintained device in satin aluminum. Both hold the door released until reset, like the 6921, but present as a single button or rotary rather than an engraved plate.
6) I need a momentary exit switch instead of the maintained DynaLock 6921 - what should I order?
The 6921 is the alternate action (maintained) DPDT configuration, which latches its state on each press. For momentary operation, where the contact transfers only while pressed, the ACSI 1320-1-MOM-ER pushbutton switch marked Emergency Release and the RCI 909 Series flush mount momentary rocker switch rated 250VAC 10A are both momentary devices. The RCI 950 Series round push plate with handicap symbol is also a momentary switch if you want a plate rather than a button.
7) Is a Trine 342 electric door switch a substitute for the DynaLock 6921?
Not for the same opening. The Trine 342 is a narrow style electric door switch, sized for narrow stile aluminum and similar tight mullions. The DynaLock 6921 is a double gang pushplate machined from solid aluminum, so it needs the wider double gang footprint. Use the Trine 342 where stile width rules out a double gang plate, and the 6921 where you have the width and want engraved PUSH TO EXIT signage.
8) My drawing calls for an ADA accessible actuator - is the DynaLock 6921 the right pick or should I use the RCI 950HP?
The RCI 950HP is a round push plate that carries the handicap symbol and operates as a momentary switch, so it is the one to use where the drawing calls for a marked accessible actuator. The DynaLock 6921 is engraved PUSH TO EXIT rather than with an accessibility symbol, and is an alternate action DPDT double gang plate. Match the marking the drawing specifies rather than substituting one graphic for the other.
9) Does the DynaLock 6921 pushplate come marked for egress, or do I add a label?
The signage is machined in, not stuck on. Every model in the 6901 Series is engraved PUSH TO EXIT, with black lettering at a 1/8 inch stroke and a minimum 1 inch character height. That is the whole point of these plates for AHJ sign-off on an electrified egress door, so there is nothing to field label.
10) Is a solid aluminum pushplate tough enough for a school or hospital exit door?
The plate is machined from solid aluminum and rated heavy duty and commercial, and the series is built tamper resistant, which is the reason it gets specified on high traffic egress openings rather than a plastic-bodied button. For a facility standardizing on one exit release, the 6901 Series plates give you the same engraved plate across every door with only the switch action changing per opening.
11) What are my alternatives to a DynaLock double gang pushplate for a request to exit button?
Depends on what the opening needs. For a round plate with the handicap symbol, the RCI 950 Series momentary push plate is the closer match. For an emergency release that a user has to deliberately operate, look at the ACSI 1320-1-MOM-ER marked Emergency Release or the Securitron EEB with interchangeable LED lenses. If you want the button lit, the Securitron PB4L illuminated halo or PB5 medium round illuminated button. The DynaLock 6921 is the choice when you need engraved PUSH TO EXIT signage on a solid aluminum two-gang plate with maintained DPDT switching.
12) Can I use the 6921 pushplate as a keyed release instead of a push button?
No. The 6921 is a push-operated plate, so anyone can release the door by pressing it, which is what egress code usually wants but not what you want on a controlled entry. For key-operated control use a mortise keyswitch such as the ACSI 1310-1 instead.
13) Does the 6921 have a built-in time delay for a delayed egress door?
No timer in the 6921. It is straight maintained DPDT switching. The pneumatic time delay option in this series is the PTD version, and those plates carry the higher 10 A at 125VAC contact rating. If your opening needs a timed unlock, order the PTD model rather than this one.
14) I have to match existing bronze and brass hardware on an egress door - does the DynaLock 6921 or a Securitron PB3 give me more finish choice?
The DynaLock 6921 double gang pushplate is 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, with US28 as the standard finish. The Securitron PB3 Series push buttons are a separate push button line, so if the job calls for a plate that matches decorative brass or bronze trim, the 6921 finish range is the one to spec against.
15) Which push button should I use instead of the DynaLock 6921 if the exit device needs to be visible in a dark corridor?
The DynaLock 6921 is a solid aluminum double gang plate with black PUSH TO EXIT lettering at 1 inch minimum height and 1/8 inch stroke - legible but not illuminated. If you want a lit device, the Securitron PB4L offers an illuminated halo around a stainless push button, the Securitron PB5 is a medium round illuminated push button, and the Securitron EEB emergency exit push button uses interchangeable LED lenses. All three trade the engraved plate format for an illuminated button.
16) Can I use an ACSI 1310-1 mortise keyswitch in place of the DynaLock 6921?
They are not interchangeable in function. The ACSI 1310-1 is a mortise keyswitch, so it requires a key to operate and mortises into the frame or door. The DynaLock 6921 is a tamper resistant double gang pushplate with engraved PUSH TO EXIT signage, intended for free egress by anyone pressing the plate. Choose the keyswitch for authorized-only control and the 6921 where the code or mandate calls for a labeled push to exit device.
17) Which of these exit switches carries a double pole double throw contact arrangement like the DynaLock 6921?
The DynaLock 6921 is the DPDT - double pole double throw - configuration in the 6901 Series, which lets you switch two independent circuits from one plate, such as a maglock and a signal to the access control panel. Among the alternatives, the RCI 909F-MO is a momentary rocker switch and the RCI 919 is a rotary release, both single-device switches, so if your wiring diagram needs two poles transferred together, stay with the 6921 rather than substituting a simpler button.
