ACSI 1355-1 – Frequently Asked Questions
1) Will the ACSI 1355-1 keypad work with my maglock or electric strike?
The 1355 Series keypads are built to control any electric locking device, so a maglock, electric strike, or electric bolt all wire the same way. The 1355-1 switches through a main relay rated 5A form C at 24VDC with a 10A surge, which is the contact you run the lock power through. Note that on the 1355-3, 1355-4 and 1355-6 that relay drops to 2A, so if you are sizing for an inrush-heavy strike, the 1355-1 is the one with the headroom.
2) What voltage does the ACSI 1355-1 keypad need, and can I run it off my existing 12V access control power supply?
Yes. The 1355-1 takes 10-30 VDC or 12-24 VAC and auto adjusts, so a standard 12VDC or 24VDC access power supply feeds it directly with no jumper to set. That range also means one supply can run the keypad and the lock off the same 12 or 24 volt bus. The 1355-5 is the exception in the series, running 12-24VAC/DC.
3) How many user codes does the ACSI 1355-1 hold, and how long can the codes be?
120 users, with each code 1 to 6 digits and repeated digits allowed. For a small office, a tenant suite, or a mechanical room that a handful of trades need into, 120 is plenty and the 6 digit ceiling lets you issue codes that are not trivially guessable. If you are running a facility where you need to issue and retire hundreds of individual codes, look at the SDC 918 Series instead, which we list at 500 user capacity.
4) Can the ACSI 1355-1 keypad be mounted outside on an exterior door?
No. The 1355-1 is an indoor keypad and is not built for weather exposure. For an exterior opening, go to the SDC 926 Series outdoor digital keypad with weather protection, or the SDC EntryCheck 920 Series, which we list as indoor/outdoor and adds a proximity reader. Putting an indoor keypad on a weather-exposed door is the most common way one of these fails early.
5) How do people get out through a door controlled by an ACSI 1355-1 keypad?
The 1355-1 has a request-to-exit switch input, so a REX device on the secure side, a push button, a motion sensor, or the REX switch in an exit device, drops the lock for egress without a code being entered. You wire that device into the REX input on the keypad. This is how you handle the egress side of an opening where the keypad only controls entry.
6) What is the difference between the ACSI 1355-1 keypad and the SDC 918 keypad?
Both are indoor digital access control keypads that release an electric locking device on a valid code. The ACSI 1355-1 is a keypad-programmable unit with 120 user capability, codes of 1 to 6 digits, a 1 to 90 second adjustable relock delay, and a 5A form C main relay at 24VDC. The SDC 918 Series is an indoor digital access control keypad rated for 500 users. If the opening is a shared entrance where the code list runs into the hundreds of holders, the 918 covers that user count; for a single door with a fixed crew, the 1355-1 handles it with a request-to-exit input and a panic output built in.
7) The keypad is going on an exterior door that gets rain and freezing weather - what should I use instead of the ACSI 1355-1?
The 1355-1 is a digital indoor keypad, so an exposed exterior jamb is the wrong opening for it. The SDC 926 Series is an outdoor digital keypad with weather protection and 500 user capacity, which is the direct swap for a door in the weather. The SDC 920 Series EntryCheck is another route - it is rated indoor/outdoor and carries a proximity reader alongside the keypad, so the same unit works for an exterior door where some users badge and some type a code.
8) I need a keypad that also reads badges - does the ACSI 1355-1 do that?
The 1355-1 is a digital keypad, so entry is by code - 1 to 6 digits, up to 120 users, with non-volatile memory that holds the codes and instructions when power is removed. For an opening where cards or fobs are also in play, the SDC 920 Series EntryCheck is an indoor/outdoor digital keypad with a proximity reader, and the SDC 923 Series EntryCheck is the same keypad-plus-proximity combination in a narrow body. Choose on how the users are credentialed: code only points to the 1355-1, mixed code and credential points to the 920 or 923.
9) Do I lose all the programmed codes on the ACSI 1355-1 if the building loses power?
No. The 1355-1 uses non-volatile memory, so user codes and programming instructions survive a power loss and the keypad comes back configured when power returns. That matters on a standalone unit like this one, because there is no head end or server holding a copy of your code list. Nothing to reprogram after an outage.
10) Do I need a computer or software to program the ACSI 1355-1 keypad?
No software, no laptop, no controller. The 1355-1 is keypad programmable, meaning you enter a master code at the keypad itself and add or delete user codes and set the timing right there at the door. That makes it a fit for a single opening where running a network drop or standing up access control software is not worth it. The Securitron DK-12 is another stand alone keypad of the same kind if you are comparing.
11) Can I set how long the door stays unlocked after someone enters a code on the ACSI 1355-1?
Relock delay on the 1355-1 is adjustable from 1 to 90 seconds. Set it short, a few seconds, for a normal walk-through door, or stretch it out for a dock door or a storage room where someone is carrying material through. If you need longer than 90 seconds, the 1355-6 in the same series goes to 255 seconds.
12) Can I leave a door unlocked during business hours with the ACSI 1355-1 keypad?
Yes. The main relay does ON/OFF latching, a toggle mode, so a code can hold the door unlocked rather than just pulsing it. Open the office at 8 and toggle it, lock it back at close. Useful on a front entry or a common area door in a multi-tenant building where you do not want staff badging every visitor in.
13) Does the ACSI 1355-1 keypad have a duress or panic output I can tie into an alarm?
It does. The 1355-1 carries a panic output and a remote alarm panel interface capability, so it can signal an alarm panel from the keypad. That is worth having on a cash room, a pharmacy, or a lone-worker entry. Two models in the series, the 1355-5 and 1355-6, do not have the panic output, so if that function is what you are buying for, the 1355-1 is the one to order.
14) What is the difference between a keypad-only unit like the ACSI 1355-1 and a keypad with a card reader?
The 1355-1 is code entry only, 120 users, each with a 1 to 6 digit code. Nobody carries a credential and nothing gets lost, but codes get shared and you cannot tell one user from another at the door. A combined unit like the SDC EntryCheck 920 Series or the narrow 923 Series adds a proximity reader, so you can issue cards or fobs and pull one back when someone leaves. If your turnover is high, or the door needs a credential you can revoke individually, go with a prox-equipped unit. For a fixed group of people on one door, the keypad is simpler and there is nothing to issue.
15) I need a keypad that fits on a narrow aluminum storefront stile. Is the ACSI 1355-1 the right one?
For a narrow mullion or storefront stile, look at the SDC EntryCheck 923 Series, which we carry specifically as a narrow keypad with a proximity reader and is rated indoor/outdoor. That is the form factor built for the tight vertical face of a glass front door. The ACSI 1355-1 is an indoor keypad and a glass front entry is usually weather exposed on the exterior side as well, so it is the wrong pick for that opening.
16) There is not enough room on the mullion for a full size keypad - what fits a narrow stile?
The SDC 923 Series EntryCheck is a narrow digital keypad with a proximity reader for indoor and outdoor access control, and the narrow body is what makes it the one to look at on an aluminum stile or a mullion. The ACSI 1355-1 is a standard indoor keypad and is the choice where the mounting surface is a wall or a wide frame rather than a narrow stile.
17) Is the Securitron DK-12 a substitute for the ACSI 1355-1 keypad?
They serve the same job in the same way. The Securitron DK-12 is a stand alone digital keypad, meaning it makes the unlock decision at the door with no panel behind it, and the ACSI 1355-1 works the same way - it is keypad programmable and controls any electric locking device directly. Where the 1355-1 is specific is the electrical envelope and the outputs: 10-30 VDC or 12-24 VAC auto adjusting input, a 5A form C main relay at 24VDC with 10A surge, a request-to-exit switch input, a panic output, main relay ON/OFF latching for toggle mode, and remote alarm panel interface capability. Match those against the lock current draw and the auxiliary wiring already in the door before treating the two as interchangeable.
18) I am standardizing keypads across a portfolio of buildings - how do I pick between the ACSI 1355 and the SDC EntryCheck units?
Sort the openings by exposure and by credential first. Interior doors on code-only entry are where the ACSI 1355-1 sits: commercial-rated, 120 users, non-volatile memory so the code list survives a power loss, and a request-to-exit input for the egress side. Exterior doors go to the SDC 926 Series, an outdoor keypad with weather protection and 500 user capacity, or to the SDC 920 Series EntryCheck if those doors also need proximity credentials indoors or out. Narrow stiles go to the SDC 923 Series. High-headcount interior doors are where the SDC 918 Series and its 500 user capacity comes in. That gives one part per opening condition rather than one part for the whole portfolio.
19) Is the ACSI 1355-1 keypad rated for commercial use or is it a residential unit?
Commercial. ACSI lists the 1355 Series for commercial, industrial and residential use, and the 1355-1 is classed as a commercial product. So it is appropriate for a tenant space, a warehouse, or a facility back-of-house, and it will also do the job on a residential common door in an apartment building.
20) Does the ACSI 1355-1 keypad show any indication that a code was accepted?
Yes, the 1355-1 has LED status indicators, so the user gets visible feedback at the keypad on code entry and lock state. Every model in the 1355 Series carries them except the 1355-4. Small thing, but it cuts down on the calls from people standing at a door not knowing whether it took their code.
