SDC 920 – Frequently Asked Questions

1) Will the SDC EntryCheck 920 keypad hold up mounted outdoors on an exterior door?
Yes. The EntryCheck 920 Series is an indoor/outdoor keypad rated from minus 4 degrees F to +140 degrees F (minus 20 C to +60 C), so it covers most of the continental US year round. The housing is heavy cast and vandal resistant, with cast metal blue backlit keys rather than a membrane pad, which is what matters on an exposed entry where a rubber overlay would fail. A built-in tamper switch reports if someone tries to pull the unit off the wall.
2) What is the difference between the SDC 920, 920P, 920PW and 921P keypads?
Four models, and the choice comes down to whether you need a card reader and whether the keypad runs the door itself or reports to a panel. The 920 is a self-contained keypad only. The 920P is self-contained and adds an integrated proximity reader. The 920PW has the proximity reader but sends Wiegand output, so it is a reader for an existing access control panel rather than a standalone door controller. The 921P has the proximity reader with external electronics, meaning the control board mounts inside the secure side instead of behind the keypad.
3) Should I use a self-contained keypad or a Wiegand reader for a single door?
For one opening with no head-end panel, a self-contained unit is the whole system: the SDC 920 or 920P stores the users and switches the lock itself, with four outputs (two relay, two solid state) that can be set timed or latching. Pick the Wiegand version, the 920PW, only when you already have an access control panel making the decisions, because it passes credentials up and does not release a lock on its own. Buying the Wiegand model for a standalone door leaves you with no controller.
4) Can I use a card and a keypad on the same door with the SDC 920P?
The 920P and 921P include an HID proximity reader and run in three modes: PIN or card, card only, or card plus PIN. That lets you run cards for daily staff and switch the same door to card plus PIN for after-hours dual credential, or hand a PIN to a contractor who does not get a card.
5) Why would I pick the 921P with external electronics over the 920P?
Both carry the proximity reader; the difference is where the brains sit. On the 920P everything, including the relays that release the lock, is inside the keypad on the unsecured side. The 921P puts the electronics separately, so pulling the keypad off an exterior wall does not expose the lock relay contacts. On a high exposure exterior door or anywhere an installer is following a spec that forbids controller electronics outside the secure perimeter, the 921P is the one to order.
6) What can I use instead of the SDC EntryCheck 920 keypad if the reader is going on an interior door only?
The ACSI 1355-1 is a digital indoor keypad, so it is aimed squarely at interior openings. The SDC EntryCheck 920 Series is rated indoor/outdoor and carries a temperature range of minus 4 degrees F to +140 degrees F (minus 20 degrees C to +60 degrees C), which is what lets it go on an exterior door face. For a lobby vestibule, a stairwell, or an interior office suite door where the keypad never sees weather, the 1355-1 covers the same basic job of PIN entry at the door; for a gate, a loading dock, or any exterior wall, stay with the 920 Series.
7) Is the Securitron DK-12 a direct swap for an SDC 920 keypad?
The Securitron DK-12 is a stand alone digital keypad, which puts it in the same role as the self-contained SDC EntryCheck 920 and 920P: the keypad itself holds the codes and switches the lock output, with no separate control board in the loop. Where they part company is what else the SDC line can do. The 920 Series also includes the 920PW, which is a Wiegand output keypad with integrated proximity reader, and the 921P, which puts the electronics outside the keypad housing. If the opening is a straight stand-alone PIN entry, the DK-12 and the self-contained 920 are aimed at the same job; if the keypad has to report to a head-end panel over Wiegand or you need the electronics on the secure side, that is a 920PW or 921P and the stand-alone unit will not do it.
8) I need card credentials at the door, not just a PIN. Which keypad handles that?
Reach for the SDC EntryCheck 920P, 920PW, or 921P. All three carry an integrated proximity reader in the same housing as the keypad, so one device on the wall handles both the card and the code. The base SDC 920 is keypad only, and the two common alternates in this class, the ACSI 1355-1 digital indoor keypad and the Securitron DK-12 stand alone digital keypad, are keypads as well. If the credential plan calls for prox cards now or later, specify one of the P models up front rather than mounting a keypad and adding a separate reader beside it.
9) How many users and what PIN length does the SDC EntryCheck 920 keypad support?
Up to 500 users, each with a PIN of one to six digits. That is enough to code every tenant in a mid-size multi-family building or every staff member on a departmental door individually, so a departure means deleting one code instead of rekeying the whole door.
10) How much power does the SDC 920 keypad draw, and will it run off my existing access control supply?
Draw is 30mA typical and 150mA maximum. That is small enough that it rarely drives the power supply choice, so size the supply around the lock: a mag lock or electric strike will pull far more than the keypad does. Budget the 150mA peak plus your lock current on the same shared supply.
11) What stops someone from standing at the keypad and guessing codes?
The EntryCheck 920 has keypad tamper lockout, which shuts the pad down after repeated bad entries rather than letting a guesser keep trying, plus a built-in tamper switch on the housing. It also runs timed anti-passback and anti-tailgate, so a credential that just went through cannot be immediately reused to walk a second person in behind the first.
12) What else does ZenSupply carry if I only need a basic indoor digital keypad?
For a plain interior door with no card reader and no weather exposure, the ACSI 1355-1 digital indoor keypad from the 1355 Series or the Securitron DK-12 stand alone digital keypad are the simpler options. The SDC 920 Series is what you want when the pad is going outside or on an opening that takes abuse, since it is the one specified for minus 4 F to +140 F service in a heavy cast vandal-resistant housing.
13) Can the SDC 920 keypad hold a door unlocked during business hours?
Yes. The self-contained models give you four outputs, two relay and two solid state, and each can run timed or latching. Latching is what you use to unlock a lobby door in the morning and leave it released until someone latches it back at close; timed is the normal momentary release for a single entry.
14) Is the SDC EntryCheck 920 keypad suitable for a commercial or institutional building?
It is built as a commercial device, not a residential one, and is used on healthcare, education, government, industrial and multi-tenant residential openings. Two things drive that: the 500 user capacity, which lets a facility give every person a unique PIN instead of sharing one door code, and the cast vandal-resistant housing for openings the public touches.
