ACSI 1320-1 Pushbutton Switches , Single Gang , Maintained, DPDT

The 1320-1 is a maintained switch, so it latches in the position you press it into and holds that state until it's pressed again. That's the behavior you want for a door you need to hold unlocked, say a lobby door propped open for a move-in or a delivery window. If you need the door to release and re-secure the instant the button is let go, a maintained button is the wrong choice and you want a momentary release instead, such as the RCI 909 Series flush mount momentary rocker.

DPDT means double pole, double throw: two independent sets of contacts, each switching between a normally open and a normally closed path. In practice that gives you two circuits off one button press, so you can break power to a maglock or strike on one pole and use the second pole for a shunt to the alarm panel, a status input, or an indicator. Most exit buttons only give you one set of contacts, so the second pole is the reason to pick this one.

It's a single gang, wall mount device, so it goes into a standard single gang box or single gang mud ring in the wall beside the opening. Plan the back box in with your rough-in; there's no surface enclosure implied here.

No. The 1320-1 is not ADA compliant, so it should not be used as the actuator on an opening where a barrier-free push control is required. For that application you want a push plate style actuator with the handicap symbol, like the RCI 950 Series round push plate in satin stainless.

The ACSI 1320-1 is a single gang, wall mount maintained release pushbutton with a DPDT contact. The nearest peer by behavior is the DynaLock 6115A, a one-pushbutton 1 gang unit with alternate action, which is the same latching push-on/push-off behavior in the same single gang footprint. On the RCI side, the 908 Series electronic exit button is offered with maintained operation and red EXIT text, and the RCI 919 Series rotary release button is offered with maintained operation in a satin aluminum finish. All three hold their state after the press the way the 1320-1 does, so any of them will drive a mag lock or door system input that expects a latched contact rather than a pulse.

Momentary devices are the common mis-substitution. The RCI 950 Series round push plate with the handicap symbol is a momentary switch, and the RCI 909 Series flush mount rocker is a momentary switch rated 250VAC 10A. Both close only while pressed and release when the hand comes off, so they pulse the door circuit. The ACSI 1320-1 is a maintained device with a DPDT contact - it stays in the position it was pushed to. If the panel or door system expects a held state, a momentary plate or rocker will not hold the door released, and if it expects a pulse, the maintained 1320-1 will hold the circuit until someone presses it again.

The ACSI 1320-1 is a single gang wall mount interior style pushbutton. For an opening exposed to weather, the DynaLock 6171 Series is a weatherproof pushbutton with a blank faceplate, built for that condition in the same push-to-release role. Specify the blank faceplate version if you do not want text on the plate at an exterior location.

The ACSI 1320-1 is not an ADA compliant device. Where the drawing calls for an accessible actuator, the RCI 950 Series round push plate carries the handicap symbol and is finished in satin stainless steel, which is the device buyers specify for that symbol requirement. Keep in mind the 950 push plate is a momentary switch while the 1320-1 is maintained, so the door control input has to accept a pulse.

The ACSI 1320-1 is a standard release pushbutton for a door system input, not an emergency device. For an egress release position, the Securitron EEB is an emergency exit push button supplied with interchangeable LED lenses, so the button reads as an emergency actuator and the lens color can be matched to the facility's convention. That is the device to specify where the release has to be identified as emergency egress rather than a general request to exit.

It's a single gang interior wall mount button and nothing in its makeup addresses weather exposure, so keep it on the protected side. For an exterior door, gate, or wash-down area, use a weatherproof button such as the DynaLock 6171 Series weatherproof pushbutton with blank faceplate.

A single gang wall button like the 1320-1 is the right pick where the release is operated deliberately by staff at a fixed station, and its maintained action lets you hold the door in an unlocked state. A palm switch, like the DynaLock 6210 Series alternate-action SPDT, presents a large strike area for someone approaching with full hands or a cart. Note the 6210 is SPDT, one set of contacts, where the 1320-1 gives you two.

It's a release pushbutton, not an emergency egress station, and its maintained action means a press leaves the circuit latched rather than releasing and resetting. For a dedicated emergency release at the opening, use a purpose-built device such as the Securitron EEB emergency exit push button with interchangeable LED lenses.

A palm switch or large plate gives a hands-busy user something to hit with a forearm, elbow, or cart. The DynaLock 6210 Series palm switch button is an alternate-action SPDT device, which latches like the ACSI 1320-1 but presents a palm-sized target instead of a single gang button. The RCI 950 Series round push plate carries the handicap symbol and is a momentary switch, so it suits an opening where the door system wants a pulse rather than a held contact. Note the 6210 palm switch is SPDT, a single set of contacts, while the 1320-1 is DPDT and can switch two independent circuits from the one press.

The Trine 342 is a narrow style electric door switch, which fits a narrower reveal than the single gang wall mount format the ACSI 1320-1 uses. That matters on aluminum storefront mullions and narrow jamb returns where there is no room for a single gang plate. Confirm the door control input accepts the 342's switching before you commit, since the 1320-1 is a maintained DPDT device.

The ACSI 1320-1 is a plain single gang release pushbutton. If you want the actuator to be visible in a dim corridor or to show its state, the Securitron PB4L Series is a stainless push button with an illuminated halo, and the Securitron PB5 Series is a medium round illuminated push button. The Securitron PB3 Series is the non-illuminated push button in that family. On a maintained circuit an illuminated button is what tells a property manager at a glance whether someone left the door in the released position.

No. The DynaLock 6300 Series is an audible annunciator operating on 6 to 28 VDC - it makes a sound on a condition, it does not release a door. The ACSI 1320-1 is the switching device, a maintained DPDT release pushbutton. The 6300 is an addition to a door control circuit alongside a release button, not a replacement for one.

Three peers to the ACSI 1320-1 are offered in maintained operation: the DynaLock 6115A one pushbutton in alternate action, the RCI 908 Series electronic exit button with red EXIT text, and the RCI 919 Series rotary release button in satin aluminum. Standardizing on maintained devices keeps the door control wiring identical at every opening, and it lets you mix formats - a labeled EXIT button at a public door, a rotary release at a controlled door - without changing how the panel input behaves.

The ACSI 1320-1 is a maintained DPDT release pushbutton intended for a door system input. Where the switch itself has to carry a heavier load, the RCI 909 Series flush mount rocker is rated 250VAC 10A, though it is a momentary device and is offered in a beige finish. If you need both the higher rating and a held state, use the 909's rating through a relay driven by a maintained device rather than expecting one button to do both.

Commercial. It's an electronic access control device in ACSI's 1300 Series, intended for commercial door systems rather than home use, so it fits multi-family common areas, offices, schools, and healthcare corridors where an access control panel or maglock circuit is already in place.

There's one configuration: model 1320-1, the single gang maintained DPDT release button. No handing, no finish selection, no function suffix to work out, so the part number is the whole order.

The ACSI 1320-1 is a maintained DPDT pushbutton - one press latches it, a second press returns it. The RCI 919 Series rotary release button is also a maintained device, in a satin aluminum finish, but it is turned rather than pushed. The rotary action takes a deliberate motion, which is why it appears at doors where an accidental palm or shoulder contact should not release the opening. Both hold their state, so the panel wiring is the same either way.
