ACSI 1355-2 – Frequently Asked Questions
1) What voltage does the ACSI 1355-2 keypad need, and can I run it off my existing 12V or 24V power supply?
The 1355-2 runs on 10-30 VDC or 12-24 VAC and auto adjusts, so a standard 12VDC or 24VDC access control supply powers it with no jumper changes or separate transformer. That covers most existing door supplies already feeding a mag lock or strike.
2) Can the ACSI 1355-2 keypad drive an electric strike or maglock directly, or do I need a separate relay?
No separate relay board is needed. The 1355-2 has an onboard main relay rated 5A form C at 24VDC with a 10A surge, wired straight to an electric strike, mag lock or other electric locking device. Form C gives you both normally open and normally closed contacts, so fail secure strikes and fail safe mag locks both wire from the same unit. Check your lock's inrush current against that 5A rating before you commit.
3) How many users can the ACSI 1355-2 keypad hold, and how long can the codes be?
120 users, with each code 1 to 6 digits and repeated digits allowed. That suits a single tenant suite, a shop, a mechanical room or a small multi-family common door where every resident gets a unique code. For a building where you are handing out codes to hundreds of people, an SDC 918 or 926 Series keypad carries 500 users.
4) Do I need a computer or programming software to set up the ACSI 1355 keypad?
Everything is programmed at the keypad itself. No laptop, no software, no reader interface. Codes and settings are entered on the pad, and non-volatile memory holds them when power is removed, so a power outage or a swapped transformer does not wipe your user list. That is what makes it a workable standalone door for a property manager who does not want a head-end system.
5) How long does the door stay unlocked after a valid code on the ACSI 1355-2, and can I hold it unlocked during business hours?
Relock delay is adjustable from 1 to 90 seconds, so you can set a short 3 to 5 second release for a normal entry or stretch it out for a delivery door. For daytime free access, the main relay also has an ON/OFF latching toggle mode: enter the code once and the door stays unlocked until it is toggled back. If you need a longer single-shot delay than 90 seconds, the 1355-6 in the same series goes to 255 seconds.
6) How does someone get out from inside a door controlled by an ACSI 1355 keypad?
The 1355-2 has a request-to-exit switch input, so an interior push button, motion sensor REX or the REX switch built into an exit device wires back to the keypad and releases the lock on the way out. You supply that egress device separately; the keypad only takes the input. Getting egress right is a code requirement on most commercial openings, so plan the REX in with the keypad rather than after.
7) Does the ACSI 1355-2 keypad read prox cards or fobs as well as codes?
Code entry only. The 1355-2 is a digital keypad with no credential reader, so anyone entering has to key a PIN. If your tenants or staff carry prox cards and you want both options at the door, a combination unit like the SDC EntryCheck 920 Series pairs a keypad with a proximity reader, and the SDC EntryCheck 923 Series does the same in a narrow housing for a mullion or glass front door stile.
8) What is the closest equivalent to the ACSI 1355-2 keypad for an exterior door?
The ACSI 1355-2 is a weather resistant digital keypad rated for indoor/outdoor use, so the direct peer is the SDC 926 Series outdoor digital keypad with weather protection and 500 user capacity. Both are standalone keypads for exterior openings; the ACSI 1355-2 supports 120 users while the SDC 926 is a 500 user unit, so pick by how many distinct codes the site needs to hand out. The SDC EntryCheck 920 Series is also an indoor/outdoor keypad and adds a proximity reader if the site wants credentials as well as codes.
9) I only need a keypad on an interior office door - is there a simpler option than the ACSI 1355-2?
For a protected interior opening the weather resistant construction of the ACSI 1355-2 is not doing any work. 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, both of which cover a code-entry interior door. Keep the ACSI 1355-2 where the keypad sees rain, wind or temperature swings, since it is built for indoor and outdoor duty.
10) The ACSI 1355-2 is too wide for my aluminum storefront mullion - what should I use instead?
On a narrow stile or mullion, reach for the SDC EntryCheck 923 Series, a narrow digital keypad with proximity reader built for indoor/outdoor access control. It covers the same exterior exposure the ACSI 1355-2 is built for as a weather resistant indoor/outdoor keypad, in a narrow body that suits a glass front frame member.
11) Is the SDC 918 a drop-in replacement for an ACSI 1355-2 on a gate?
Not for an exposed gate. The SDC 918 Series is an indoor digital access control keypad, while the ACSI 1355-2 is weather resistant and rated for indoor and outdoor use. For a gate or other unprotected location the SDC 926 Series, an outdoor keypad with weather protection, is the peer that matches the exposure; the SDC 918 is the right call only where the keypad is under cover.
12) Which ACSI 1355 model should I order, the 1355-2 or one of the others?
The 1355-2 is the weather resistant one, and it carries the full feature set: LED status indicators, panic output, and the higher 5A form C main relay. The 1355-3, 1355-4 and 1355-6 step the relay down to 2A. The 1355-4 drops the LED status indicators. The 1355-5 runs 12-24VAC/DC and, like the 1355-6, has no panic output. If you want the strongest relay and the panic output on an exterior door, the -2 is the one to specify.
13) Can the ACSI 1355-2 keypad tie into an alarm panel or trigger a duress signal?
Two outputs handle that. The 1355-2 has a panic output for a duress or emergency signal, plus remote alarm panel interface capability so the keypad reports to an existing alarm system rather than standing entirely alone. That matters on a back-of-house or cash-handling door where someone forced to open it needs a silent way to signal.
14) What is a good alternative to the ACSI 1355-2 for a standalone keypad on an exterior door?
Two other outdoor-capable standalone keypads worth weighing: the SDC 926 Series is an outdoor digital keypad with weather protection and 500 user capacity, which is the move if 120 users is too tight; the Securitron DK-12 is a stand alone digital keypad. Where the 1355-2 earns its place is the 5A form C relay and the panic output, so if you are switching a heavier lock load directly from the keypad, stay with the ACSI.
15) I have a keypad on a gate or a garage door operator. Can the ACSI 1355-2 replace it?
It can, as long as the device you are switching is electrically operated. The 1355-2 is built to control any electric locking device, its relay is a dry form C contact rated 5A at 24VDC with 10A surge, and it takes 10-30 VDC or 12-24 VAC, which covers most gate and operator control voltages. Weather resistance means it can live on an exterior post or wall. Match your operator's input contact requirement to that relay rating before you order.
16) Does the ACSI 1355-2 read prox cards, or do I need a different unit?
The ACSI 1355-2 is a keypad - access is by code, with codes of 1 to 6 digits and 120 users stored in non-volatile memory. If the site issues fobs or cards, the SDC EntryCheck 920 Series and the narrow SDC EntryCheck 923 Series are both keypads with an integrated proximity reader, so one device handles code entry and credentials. Substituting a 920 or 923 for the ACSI 1355-2 changes the credential type, not just the housing.
17) I need more than 120 codes for an apartment building - what keypad handles that?
The ACSI 1355-2 stores 120 users. Where a property needs a code per unit beyond that, the SDC 918 Series indoor keypad and the SDC 926 Series outdoor keypad are both 500 user capacity units - the 926 carries weather protection for an exterior entry, the 918 is the indoor version. Match the exposure first, then the user count.
18) Will the ACSI 1355-2 work as a standalone unit without an access control panel?
Yes. The ACSI 1355-2 is keypad programmable and controls any electric locking device directly through its own main relay, with a request-to-exit switch input, so it does not need a head-end panel. The Securitron DK-12 is likewise a stand alone digital keypad, and the SDC 918, 920, 923 and 926 Series are all standalone keypads, so a swap in either direction keeps the door on local control.
19) I need a keypad that switches a 5A relay for a commercial mag lock circuit - which one?
The ACSI 1355-2 carries a 5A form C main relay at 24VDC with a 10A surge rating and runs on 10-30 VDC or 12-24VAC auto adjusting, which is the heavier relay in the 1355 range - the 1355-3, 1355-4 and 1355-6 models are 2A. It is a commercial-rated device, so where a specification calls out relay capacity for the locking device the 1355-2 is the model to hold rather than dropping to a lighter unit.
