DynaLock 6620 – Frequently Asked Questions
1) Does the DynaLock 6620 REX button come with a surface back box?
That's the ordering choice on the 6620. It's sold either with a narrow surface back box or without one. Pick the back box if you're mounting on a hollow metal mullion or any face where you can't recess the switch behind the surface; skip it if the mullion is already prepped with a cavity for the switch body.
2) What voltage does the DynaLock 6620 exit button run on, and can I power it off the same supply as my maglock?
Selectable input of 10 to 24VDC, so it drops onto the same 12 or 24VDC supply feeding a mag lock or strike without a separate transformer. The switch itself only draws power for the halo LED and the internal relay; the lock current runs through the dry contacts, not the input.
3) Can the 6620 piezo button switch my door lock directly, or do I need an access control relay in between?
It can switch the lock directly. The output is an SPDT double-break (Form Z) relay rated 5 amps at 125VAC, with both N.O. and N.C. contacts available, so a mag lock or electric strike wires straight through it. You'd only add an external relay if your lock exceeds that 5 amp rating or you're routing the request through a panel for logging.
4) Can I use this DynaLock push button outdoors or in a wash-down area?
Yes. The 6620 meets IP65 for water and dust, the circuit board assembly is encapsulated, and the housing is chemical solvent repellent. DynaLock rates the 6600 Series for indoor and outdoor use, which is why it turns up on exterior gates, garages and industrial areas where a standard plastic exit button fails.
5) I need a lighted exit button for a single-gang box, not a mullion - what should I use instead of the DynaLock 6620?
The 6620 is the narrow, blank faceplate version of the DynaLock 6600 series, sized for narrow mullion mounting. Where a single-gang box is the opening, the Securitron PB5 is the medium round illuminated push button in the comparable group, and the Securitron PB4L is an illuminated halo stainless push button. The DynaLock 6600 series itself is offered in a choice of single-gang box or narrow mullion mount, with or without EXIT signage, so the wider-plate version of the same piezo switch is an option if the halo and piezo actuation are what matter.
6) What is the closest narrow-style alternative to the DynaLock 6620 REX push button for a mullion?
The Trine 342 is the narrow-style electric door switch in the comparable group, so it is the one built for the same narrow mullion or frame face the DynaLock 6620 is designed around. The 6620 differs in how it actuates and signals: it is a halo-lighted piezoelectric switch on a narrow blank faceplate, running on 10-24VDC, with a brushed stainless steel US32D face and a heavy duty rating. If the mullion width is what drove the selection, the Trine 342 covers the same narrow footprint; if the piezo touch actuation and the red/green/yellow halo ring are what the access control design calls for, the 6620 is the one that carries them.
7) Is the Securitron PB4L the same kind of illuminated push button as the DynaLock 6620?
Both are illuminated halo push buttons with a stainless face. The Securitron PB4L is described as an illuminated halo stainless push button, and the DynaLock 6620 is a halo-lighted piezo REX push button with a brushed stainless steel US32D finish. The DynaLock actuates through a soft-touch piezoelectric element with no moving plunger, is rated water and dust proof to IP65, and lets the LED ring be set to red, green or yellow and change state when the relay fires. The two are close in appearance and function; the piezo actuation and the selectable ring color are what separate the 6620 from a conventional illuminated button.
8) The DynaLock 6620 has a blank faceplate - what if the door needs a marked EXIT button?
The 6620 is the blank faceplate version, with no legend on the plate. For a marked device, the RCI 908 series electronic exit button carries red EXIT text and operates maintained, and the ACSI 1320-1-MOM-ER pushbutton switch is marked Emergency Release with momentary operation. Within the DynaLock 6600 series, the same halo-lighted piezo switch is offered with or without EXIT signage. Note the operation difference before substituting: the 6620 generates a timed dry contact pulse with a field-adjustable pulse time of 1 to 60 seconds, while the RCI 908 in maintained form holds its state until it is reset.
9) Can I use a Securitron EEB in place of the DynaLock 6620?
They serve different roles at the door. The Securitron EEB is an emergency exit push button with interchangeable LED lenses - a device intended to be operated in an emergency egress situation. The DynaLock 6620 is a request-to-exit push button that generates a timed dry contact relay pulse for direct release control of an electronic locking device or similar application, on 10-24VDC. If the drawing calls for an emergency release station, the EEB is the device type being specified; if it calls for a REX button on the egress side of an access controlled opening, the 6620 is.
10) For a wet or wash-down area, how does the DynaLock 6620 compare with a standard rocker or plate switch?
The 6620 is built for that condition: the piezoelectric switch is non-sparking, non-magnetic and corrosion resistant, the assembly meets IP65 for water and dust, the circuit board is encapsulated, and the unit is chemical solvent repellent and anti-vandal, in a brushed stainless steel US32D finish rated heavy duty. Among the alternatives, the RCI 909 series is a flush mount momentary rocker switch in a beige finish rated 250VAC 10A, and the RCI 950 series is a round push plate with a handicap symbol in satin stainless steel with a momentary switch. Those are mechanical actuators; the 6620 has no moving contact surface to admit moisture.
11) What should I specify if the opening needs a release that stays latched rather than a timed pulse like the DynaLock 6620?
The 6620 gives a timed dry contact relay pulse with a field-adjustable duration of 1 to 60 seconds through SPDT double-break Form Z contacts rated 5 Amps at 125VAC, so the lock re-secures on its own. Where the release has to stay held until someone resets it, the RCI 919 series is a rotary release button with maintained operation in a satin aluminum finish, and the RCI 908 series electronic exit button is offered with maintained operation and red EXIT text. Match the operation to the sequence the access control system expects before ordering either way.
12) How long does the DynaLock 6620 hold the door released after someone presses it?
Pulse time is field adjustable from 1 to 60 seconds, set at the switch. That covers a quick 3 to 5 second egress release as well as a long hold-open for a loading dock or a cart route, and you set it on site rather than ordering a fixed timer.
13) Is a piezo exit button worth it over a standard mechanical push plate?
The trade is moving parts versus none. A piezoelectric switch like the 6620 has no mechanical contact to wear or stick, and it's non-sparking, non-magnetic, corrosion resistant and anti-vandal, which is why it goes in high-abuse and hazardous or high-risk areas. A mechanical plate such as the RCI 950 Series round push plate is the simpler choice for a low-traffic interior office door, and the RCI 950HP carries the handicap symbol if the opening needs an accessibility marking. The 6620 is the answer when the button gets hit hundreds of times a day or lives in weather.
14) Does the DynaLock 6620 say EXIT on the faceplate?
No, the 6620 is the blank faceplate version. If the opening needs the word on the button, DynaLock offers the 6600 Series with EXIT signage as a separate model. Among other brands, the RCI 908 Series electronic exit button carries red EXIT text, and the ACSI 1320-1-MOM-ER is marked Emergency Release.
15) What else could I use instead of a DynaLock 6620 narrow REX button?
For a narrow mullion or narrow stile, the Trine 342 narrow style electric door switch is the direct alternative form factor. If you want a lit round button on a standard plate rather than a narrow one, look at the Securitron PB5 medium round illuminated push button or the Securitron PB4L illuminated halo. The Securitron EEB emergency exit push button with interchangeable LED lenses is a different animal, that's a break-glass style emergency release rather than an everyday REX. Where the release needs to be key-operated instead of a button, the ACSI 1310-1 mortise keyswitch is the swap.
16) Does the DynaLock 6620 latch on, or does it release the lock only while pressed?
Neither exactly. Pressing the soft-touch piezo generates a timed relay pulse, so the lock stays released for whatever you set the timer to, 1 to 60 seconds, then drops back. It's not a momentary contact that ends when your finger lifts, and it's not a maintained switch that stays on until pressed again. If you specifically need maintained operation, that's a different switch, the RCI 919 Series rotary release and the RCI 908 Series with maintained operation both hold their state.
17) Is the DynaLock 6620 safe to use in a hazardous or explosive-atmosphere area?
The switch is non-sparking and non-magnetic, which is the reason this button gets specified for industrial and high risk environments where a contact-arcing mechanical switch is a problem. There's no moving electrical contact at the finger, the piezo element generates the signal. For a formal area classification, work from your facility's own electrical classification requirements.
18) Does an ACSI 1310-1 mortise keyswitch substitute for the DynaLock 6620?
No. The ACSI 1310-1 is a mortise keyswitch, operated by a key cylinder and mortised into the frame or door - it is an authorized-user control, and it needs a cylinder and a mortise prep. The DynaLock 6620 is a surface or narrow mullion mounted piezo push button that anyone on the egress side can press to generate a timed release pulse, and it takes 10-24VDC. They are often on the same opening for different reasons rather than in place of one another.
19) Which alternative should I use for an ADA actuator rather than a REX button like the DynaLock 6620?
The RCI 950 series round push plate carries a handicap symbol and a momentary switch in satin stainless steel, which is the actuator style used where a marked, large-target plate is wanted at the opening. The DynaLock 6620 is a narrow blank faceplate piezo REX button on 10-24VDC with a small single-finger touch target and no legend - it is sized for a mullion, not for a wall-mounted actuator position. If both are needed, they can run to the same release circuit.
20) What color is the light ring on the DynaLock 6620 and does it change when the door releases?
The external LED halo can be set to red, green or yellow, and it changes state when the relay activates, so the button gives visual confirmation the release fired. There is also a no-illumination setting if you don't want a lit button on a dark corridor. Faceplate finish is brushed stainless steel, US32D.
21) Will the DynaLock 6620 match the US32D stainless hardware on the rest of my doors?
Faceplate is brushed stainless steel in US32D, the satin stainless finish that most commercial lever trim, push plates and exit devices are specified in, so it reads the same as the rest of a 32D opening. For a fleet standardizing on satin stainless, the Securitron PB4L illuminated halo button with a stainless push button is the closest cross-brand equivalent.
22) Is the DynaLock 6620 heavy enough for a high-traffic commercial entrance?
It's a heavy duty commercial switch, not a light-commercial or residential part. The piezo element has no mechanical wear point, the faceplate is anti-vandal, and the board is encapsulated, which is the combination you want on a door hit constantly, a stairwell, a dock, or anywhere the button takes abuse.
