ACSI 1355-5 – Frequently Asked Questions
1) Will the ACSI 1355-5 keypad mount on an aluminum storefront door frame mullion?
Yes. The 1355 Series keypad is built in a narrow style specifically for aluminum door frame mounting, which is why the 1355-5 is called a mullion keypad. It is the right shape for a narrow stile storefront frame where a full-size square keypad will not fit.
2) Can the ACSI 1355-5 keypad be mounted outside in the weather?
It is weather resistant and rated for outdoor as well as indoor use, so an exterior storefront or gate entry is a normal application. The keys are backlit and hardened, which helps in low light and on high-traffic exterior openings.
3) What power supply does the ACSI 1355-5 keypad need?
The 1355-5 specifically runs on 12-24VAC/DC. Other models in the 1355 Series accept 10-30 VDC or 12-24VAC auto-adjusting, but for the -5 plan on a 12 to 24 volt AC or DC supply sized for both the keypad and the electric lock it releases.
4) Does the ACSI 1355-5 have a panic or duress output?
No. The panic output is offered on the other 1355 Series models but is specifically excluded on the 1355-5 and the 1355-6. If a panic output is a requirement on your opening, choose a different model in the series.
5) Will the ACSI 1355-5 drive a maglock or an electric strike directly?
It is designed to control any electric locking device, and the main relay on the 1355-5 is rated 5A form C at 24VDC with 10A surge. That is enough to switch a maglock or an electric strike directly without an added relay board, provided the lock draw stays inside that rating. Note the 1355-3, 1355-4 and 1355-6 drop to a 2A relay.
6) What is the closest narrow-style alternative to the ACSI 1355-5 keypad for mounting on an aluminum storefront mullion?
The ACSI 1355-5 is a narrow-style digital keypad suited to aluminum door frame mounting and rated weather resistant for indoor or outdoor use. The nearest narrow alternative is the SDC EntryCheck 923 Series, a narrow digital keypad with a built-in proximity reader for indoor/outdoor access control. The practical difference is credential type: the 1355-5 is keypad-only with codes of 1 to 6 digits, while the 923 adds proximity credentials alongside the keypad, so choose the 923 if the site issues prox fobs and the 1355-5 if codes alone control the opening.
7) If a door is fully exposed to weather, is there an alternative to the ACSI 1355-5 keypad?
The ACSI 1355-5 is itself described as weather resistant for outdoor as well as indoor applications, with backlit hardened keys. If you want a unit built specifically around exterior exposure, the SDC 926 Series is an outdoor digital keypad with weather protection and 500 user capacity. Capacity is the other deciding factor: the 1355-5 supports 120 users, so a site needing several hundred codes would lean to the 926.
8) Does the SDC 920 do the same job as the ACSI 1355-5?
They overlap but are not interchangeable. Both are indoor/outdoor digital keypads that control an electric locking device. The SDC EntryCheck 920 Series is an indoor/outdoor digital keypad with a proximity reader, so it reads prox credentials in addition to codes. The ACSI 1355-5 is code-entry only and is the narrow style intended for aluminum door frame mounting, which the 920 is not described as. If the mounting surface is a mullion, the 1355-5 fits where a full-size reader will not.
9) How many users and what code length does the ACSI 1355 keypad support?
120 users, with codes from 1 to 6 digits and repeated digits allowed. Programming is done at the keypad itself, so no laptop or software is needed to add or remove a code. If you need larger populations, the SDC 918 Series and SDC 926 Series keypads carry 500 user capacity.
10) How long does the ACSI 1355 keypad hold the door unlocked after a valid code?
Relock delay is adjustable from 1 to 90 seconds on the 1355-5. There is also a latching toggle mode on the main relay, so you can leave the door unlocked for business hours and toggle it back at close. The 1355-6 extends the delay range to 1-255 seconds.
11) Does the ACSI 1355-5 keypad accept a request-to-exit device, and does it have a doorbell?
Both. There is a request-to-exit switch input for tying in a motion sensor or exit push button on the inside of the opening, and a dedicated doorbell key with its own relay output for visitors without a code. It also has a remote alarm panel interface capability for tying into an existing panel.
12) Do the codes get lost in the ACSI 1355 keypad during a power outage?
No. Codes and programmed instructions are held in non-volatile memory and survive loss of power, so you are not reprogramming 120 users after every outage. LED status indicators are present on the 1355-5 for feedback at the door.
13) What else could I use instead of the ACSI 1355-5 if I want a keypad and a card reader in one unit?
The 1355-5 is keypad only. For credential plus code on the same device, the SDC EntryCheck 923 Series is a narrow keypad with a proximity reader for indoor/outdoor use and is the closest match for a mullion application; the SDC EntryCheck 920 Series is the wider indoor/outdoor keypad with proximity reader. For a plain standalone keypad alternative, the Securitron DK-12 is a stand alone digital keypad.
14) What should I use instead of the ACSI 1355-5 if the keypad is going inside a lobby and never sees weather?
The ACSI 1355-5 will work indoors, since it is listed for indoor as well as outdoor use, but an indoor-only unit is a simpler match. The SDC 918 Series is an indoor digital access control keypad with 500 user capacity, and the Securitron DK-12 is a stand-alone digital keypad. Against the 1355-5's 120 user capability, the 918's 500 users is the difference that usually decides a multi-tenant lobby.
15) Is the Securitron DK-12 a drop-in replacement for an ACSI 1355-5?
Not a drop-in. The Securitron DK-12 is a stand-alone digital keypad, so it serves the same standalone code-entry role, but the ACSI 1355-5 is a narrow mullion-style housing with backlit hardened keys, a doorbell key with an associated relay output, and a request-to-exit switch input. If you are replacing a 1355-5 on an aluminum mullion, confirm the cutout and the doorbell relay are not needed before swapping to a differently shaped housing.
16) What finishes does the ACSI 1355 mullion keypad come in?
Bronze or satin aluminum, which are the two finishes that match standard aluminum storefront framing on a commercial building. Pick the one that matches the existing frame anodizing so the keypad disappears into the entrance.
17) Is the ACSI 1355-5 keypad suitable for a commercial building or only light residential use?
It is a commercial-grade unit, and the 1355 Series is used in commercial, industrial and residential applications alike. For a property manager standardizing across a portfolio, the same series gives you one programming method across multiple entrances, with model choice driven by relay rating and whether you need a panic output.
