ACSI 1355-3 – Frequently Asked Questions
1) Can the ACSI 1355-3 keypad be mounted outdoors on an exterior door?
Yes. The 1355-3 is built for indoor or outdoor use, with a weather resistant, self-contained metal housing that is also vandal resistant. That makes it workable on exterior gates, service entrances and loading doors where a plastic indoor keypad would not last.
2) What voltage does the ACSI 1355-3 keypad run on?
It accepts 10-30 VDC or 12-24 VAC and auto adjusts, so a standard 12V or 24V access control power supply or transformer will run it without a separate regulator. Note that the 1355-5 model in the same series is 12-24 VAC/DC instead.
3) Will the 1355-3 keypad drive a mag lock or electric strike directly, or do I need a separate relay?
It switches the lock itself through its onboard main relay, a form C contact. On the 1355-3 that relay is rated 2A at 24VDC, not the 5A/10A surge rating carried by other models in the 1355 series. A typical 12V or 24V electric strike or mag lock draws well under 2A, but if your locking device pulls more than that, add an external relay or pick a higher-rated model in the series.
4) How many user codes does the ACSI 1355-3 hold, and how long can the codes be?
120 users, with each code 1 to 6 digits long and repeated digits allowed. For a small office, a storage yard or a single multi-family amenity door that is plenty. If you need to issue hundreds of codes, look at something like the SDC 918 Series, which is rated for 500 users.
5) What outdoor-rated keypad can I use instead of the ACSI 1355-3?
The ACSI 1355-3 is a sealed environmental keypad built for indoor or outdoor use in a weather resistant, vandal resistant metal housing. If you need a different outdoor option, the SDC 926 Series is an outdoor digital keypad with weather protection and a 500 user capacity, which is a larger user pool than the 120 users the 1355 Series supports. Both control an electric locking device at the door.
6) What fits a narrow aluminum stile if the ACSI 1355-3 is too wide?
The ACSI 1355-3 uses a small self-contained metal housing, but on a narrow glass door stile the SDC EntryCheck 923 Series is purpose-built as a narrow digital keypad with a proximity reader for indoor and outdoor access control. Confirm the mullion or stile width against the device footprint before ordering either one.
7) Does the 1355-3 need a computer or software to program?
No PC, no software, no reader kit. Programming is done at the keypad itself, and the settings live in non-volatile memory so codes and instructions survive a power loss. That matters for property managers who add and delete tenant codes on the spot without calling an integrator back out.
8) Can I set how long the door stays unlocked after a code is entered?
Yes, the relock delay is adjustable from 1 to 90 seconds on the 1355-3, so you can set a short 3 to 5 second release on a pedestrian door or a longer hold for a dock or gate. If you need a longer hold than 90 seconds, the 1355-6 in the same series goes to 255 seconds. There is also a latching toggle mode on the main relay for holding a door unlocked during business hours.
9) Does the ACSI 1355-3 keypad have a request-to-exit input and an alarm output?
Both. There is a request-to-exit switch input, so a push button, motion sensor or exit device switch can release the lock from the secure side without the keypad. The 1355-3 also carries a panic output (omitted on the 1355-5 and 1355-6) and can interface to a remote alarm panel, which is how integrators tie duress at the door back to a monitored system.
10) What else could I use instead of the ACSI 1355-3 if I need card credentials as well as a code?
The 1355-3 is keypad only, no card or fob reading. For combined PIN plus prox at the door, the SDC EntryCheck 920 Series is an indoor/outdoor keypad with an integrated proximity reader, and the SDC EntryCheck 923 Series is the narrow version of the same idea for a mullion or narrow stile. If you only need a weather-rated code entry point, stay with the 1355-3.
11) I need a straight standalone keypad for an interior door, nothing weather rated. Is the 1355-3 overkill?
Possibly. The 1355-3 pays for a sealed metal outdoor housing you would not use inside. For a dry interior opening the SDC 918 Series is an indoor digital keypad, and the Securitron DK-12 is a standalone digital keypad as well. Keep the 1355-3 where the device sees weather or abuse, or where you want its panic output and remote alarm panel connection.
12) Is the Securitron DK-12 a direct replacement for the ACSI 1355-3?
They serve the same role but are not identical. The Securitron DK-12 is a stand alone digital keypad. The ACSI 1355-3 is a sealed environmental keypad rated for indoor or outdoor use, with 120 user capability, keypad programming, a request-to-exit switch input and a 2A main relay on the -3 model. If you are matching an existing ACSI opening for relay rating and code capacity, stay with the 1355-3; verify the mounting cutout and wiring if you swap brands.
13) Which keypad should I standardize on across a facility with a mix of interior and exterior doors?
One approach is to run the ACSI 1355-3 sealed environmental keypad at every opening, since it is rated indoor/outdoor and carries the same 120 user capability and keypad programming everywhere, so staff learn one programming sequence. If you prefer to split by location, the SDC 918 Series covers indoor doors and the SDC 926 Series covers outdoor doors, both with 500 user capacity, which matters if your user list exceeds 120.
14) Does the 1355-3 give any visual feedback when a code is accepted?
Yes, it has LED status indicators. Within the 1355 family only the 1355-4 goes without them, so if you want the user to see the door has released, the -3 covers it.
15) Is the ACSI 1355-3 keypad suitable for a commercial building, or is it a residential product?
It is classed as commercial, and ACSI builds the 1355 series for commercial, industrial and residential applications alike. In practice it lands on light commercial and MRO work: storage facilities, mechanical and electrical rooms, yard gates, and single-door multi-family entries where a standalone keypad beats running a head-end panel.
