ACSI 1355-4 – Frequently Asked Questions
1) Can the ACSI 1355-4 keypad be mounted outside on a gooseneck or post?
Yes. The 1355-4 uses a one piece, weather resistant metal housing that mounts to a wall, a post, or a gooseneck, so drive-up and gate applications are in scope. The housing is also vandal resistant, which is why it gets specified on exterior and high traffic industrial openings.
2) What voltage does the ACSI 1355-4 digital keypad run on?
The 1355-4 accepts 10-30 VDC or 12-24 VAC and auto adjusts, so it runs off most existing access control power supplies without a separate transformer. Note that the 1355-5 model in the same family is 12-24 VAC/DC instead.
3) What size lock can the ACSI 1355-4 keypad switch, and will it drive a maglock or electric strike?
The 1355-4 is built to control any electric locking device, but its main relay is rated 2 amps rather than the 5 amp form C relay used on other 1355 models. Size your maglock or strike load against that 2 amp figure; if the device draws more, run the keypad relay into a separate power supply relay or pick a 1355 model with the 5A output.
4) How is the ACSI 1355-4 different from the other 1355 Series keypads?
Two things set the 1355-4 apart within the 1355 Series: it has no LED status indicators (every other model in the series does), and its main relay is 2 amps instead of 5. It does keep the panic output, which the 1355-5 and 1355-6 drop. Feedback on the 1355-4 comes from the internal sounder rather than lights.
5) Does the ACSI 1355-4 need a separate controller or software to program?
No controller and no software. The 1355-4 is keypad programmable at the device, and it stores codes and instructions in non-volatile memory, so a power loss does not wipe the programming. It is a standalone unit, same approach as the Securitron DK-12 Stand Alone Digital Keypad.
6) We are moving from codes to fobs. Does the ACSI 1355-4 read credentials, or do I need a different unit?
The ACSI 1355-4 is a code entry keypad - it is programmed from the keypad itself and stores codes in non-volatile memory, with no credential reader in the housing. For card or fob credentials alongside a PIN, the SDC EntryCheck 920 Series is a digital keypad with an integral proximity reader for indoor or outdoor use, and the SDC EntryCheck 923 Series offers the same keypad plus proximity reader in a narrow body.
7) I need a keypad on an exterior gate post - is the ACSI 1355-4 the right choice or should I look at an SDC unit?
The ACSI 1355-4 is built for that kind of opening. It uses a weather resistant, vandal resistant one piece metal housing that mounts to a wall, post or gooseneck, so a gate post or bollard mount is within its intended use. If you would rather stay in the SDC line for an outdoor opening, the SDC 926 Series is an outdoor digital keypad with weather protection and 500 user capacity, and the SDC EntryCheck 920 Series is rated for indoor or outdoor use. The SDC 918 Series is an indoor keypad and is not the one to put on an exposed post.
8) The 1355-4 tops out at 120 users. What keypad holds more codes for a larger tenant roster?
The ACSI 1355-4 is specified at 120 user capability, with codes of 1 to 6 digits including repeated digits. If your roster runs past that, the SDC 918 Series carries a 500 user capacity for indoor openings and the SDC 926 Series carries the same 500 user capacity in an outdoor weather protected housing. Match the housing to the opening first, then the user count.
9) How many users and what code length does the ACSI 1355-4 keypad support?
120 users, with codes from 1 to 6 digits and repeated digits allowed. That covers a small office, a tenant amenity room, or a service entrance. If you are managing several hundred credential holders, look at a higher capacity unit such as the SDC 918 Series or SDC 926 Series, both of which carry 500 user capacity.
10) Can I wire a request-to-exit device and an alarm panel to the ACSI 1355-4?
Both. The 1355-4 has a request-to-exit switch input for a push button, motion sensor, or exit device switch, and it offers remote alarm panel interface capability so the opening can report to a monitored panel. It also carries a panic output.
11) Can the ACSI 1355-4 hold a door unlocked during business hours?
Yes. The main relay supports ON/OFF latching, also called toggle mode, so a valid code can hold the lock released for an open period and another entry re-secures it. For momentary unlocks the relock delay is adjustable from 1 to 90 seconds on the 1355-4 (the 1355-6 stretches that to 255 seconds).
12) My mullion is too narrow for the 1355-4 housing - what fits?
The ACSI 1355-4 uses a one piece metal housing sized for wall, post or gooseneck mounting, so a narrow aluminum stile or mullion can be tight. The SDC EntryCheck 923 Series is a narrow body digital keypad with proximity reader intended for indoor or outdoor access control, which is the form factor to look at when the mounting surface is the limit rather than the feature set.
13) Is the Securitron DK-12 a drop-in equivalent to the ACSI 1355-4?
They fill the same role but are not identical. Both are stand alone keypads that control an electric locking device without a separate panel - the Securitron DK-12 is a stand alone digital keypad, and the ACSI 1355-4 is programmed at the keypad and holds its codes in non-volatile memory when power is removed. Where the 1355-4 is distinct is its weather and vandal resistant metal housing and its 10-30 VDC, 12-24 VAC auto adjusting input, so confirm your supply voltage and exposure before swapping one for the other.
14) Which 1355 model should I order if I want LED status indication instead of just a sounder?
The ACSI 1355-4 gives status through the internal audible multi-status sounder; LED status indicators are a feature of the other 1355 Series models. Everything else in the family shares the same platform - keypad programming, 120 user capability, request-to-exit switch input and main relay latching toggle mode - so stepping to another 1355 model keeps the wiring approach the same. If you want visual feedback plus credential reading in one device instead, the SDC EntryCheck 920 Series pairs a keypad with a proximity reader.
15) What finishes does the ACSI 1355 keypad come in, and will it match other exterior hardware?
The 1355 keypads are offered in white or black. Both are the metal housing finish, so an exterior gooseneck or wall installation keeps a consistent look across a run of openings.
16) Can I use the ACSI 1355-4 on a residential gate, or is it commercial only?
The ACSI 1355-4 is catalogued for commercial use but the 1355 Series is stated to serve commercial, industrial and residential applications, and it is designed to control any electric locking device. The peers in this class are positioned for commercial access control - the SDC 918 Series for indoor openings, the SDC 926 Series for outdoor - so for a residential driveway gate the 1355-4 with its post or gooseneck mounting housing is the more directly suited option.
