Complete installation and programming manual for the SECO-LARM SK-1011-SDQ ENFORCER Access Control Keypad.
If using the keypad with a mechanically operated door or gate, mount the keypad at least 15 ft (5m) from the door or gate to prevent users from being crushed or pinned. Failure to do so may result in serious injury or death.
| Operating voltage | 12~24 VDC/VAC |
| Current draw (at 12VDC) | Standby 15mA / Keypress 30mA / Output 1 active 55mA / Total max 90mA |
| Outputs | #1 Form C: 1A@30VDC / Tamper: 50mA@24VDC |

| Weight | 6 oz (170g) |
| Tamper N.C. | Tamper switch output, N.C. contact, max 50mA@24VDC. Connect to the N.C. 24-hour protection zone of an alarm if needed. |
| 12~24 VAC/VDC | Power supply connection. Observe polarity. |
| Output 1 N.C./COM/N.O. | Relay output, max 1A@30VDC |
| Egress In | N.O. pushbutton contact to ground — press to initiate door unlock output |
Four types of keypad codes: Master code (only one per keypad, used to enter programming mode), Super user code (activates output, can disable/enable output operation, exempt from lockup), User codes (unique per-user activation codes), Visitor codes (temporary, one-time or time-limited).
On first power-up the keypad beeps continuously for ~1 minute. Turn off the beeping early with 12 #. Enter programming mode with xxxx ** (xxxx = master code, default 0000). Exit programming mode anytime with **.
Note: Do not disconnect power while in programming mode — this can cause a memory error.
| Function | Parameters | Default |
|---|---|---|
| 01 | Master code | 0000 (4~8 digits) |
| 02 | Super user code | No default, must be programmed |
| 10 | User codes | No default, must be programmed |
| 40 | Visitor codes | No default, must be programmed |
| 51 | Output mode and timing | 5-second output, momentary |
| 55 | System real-time clock | No default, must be programmed |
| 56 | Auto-disable time | No default, must be programmed |
| 60 | Wrong-code system lock-up | Locks after 10 false attempts |
| 70 | User code entry mode | Manual entry ("#" after each code) |
| 71 | Keypad sounds | Enabled |
| 72 | Output relay activation sounds | 1-second beep on activation |
| 73 | Amber LED standby flashing | Enabled |
| 90 | Egress delay/warning | Immediate, no warning |
Fixed codes (cannot be changed): DAP code 2828, system restore code 9999.
System Restore (resets everything except master code): 9999 # — may take several minutes; amber LED flashes rapidly during reset.
Set new Master Code (4-8 digits): 01 xxxx #
Set/Delete Super User Code: Set: 02 xxxx # Delete: 02 #
Program User Codes — format 10 A BBB CCCC # (A: 2=add, 5=delete, 0999=delete all; BBB: user ID 000-999; CCCC: user code). Example — add code 2275 for user ID 010: 10 2 010 2275 #
Program Visitor Codes — format 40 aa bb cccc # (aa: visitor ID 01-50; bb: duration in hours, 00=one-time; cccc: code). Example — one-time code 1268 for visitor #1: 40 01 00 1268 #
Output Mode/Timing — format 51 AAAAA # (0 = toggle mode; 1-99999 = seconds before auto-off). Example — 60-second output: 51 60 #
Real-Time Clock — format 55 HHMM # (24-hour format). Example — set to 7:15 PM: 55 1915 #
Auto-Disable Time — format 56 HHMM HHMM # (start/end, 24-hour format). Example — disable 6:30 PM to 7:30 AM: 56 1830 0730 #. Clear: 56 #
Wrong-Code Lock-Up — format 60 aa # (1 = lock 60 sec after 10 tries [default]; 5-10 = lock 15 min after 5-10 tries; 00 = disabled)
User Code Entry Mode: Auto (no # needed, all codes match master code length): 70 1 # Manual (default, # required): 70 2 #
Keypad Sounds: Audible (default): 71 1 # Silent: 71 0 #
Output Relay Sounds: No beep: 72 0 # 1-sec beep (default): 72 1 # 2 short beeps: 72 2 #
Amber LED Standby Flash: Enable (default): 73 1 # Disable: 73 0 #
Egress Delay/Warning — format 90 a bb # (a: 1=momentary no warning [default], 2=momentary with warning beep, 4=hold no warning, 5=hold with warning beep; bb: delay in seconds 0-99). Example — momentary with 5-sec warning beep: 90 2 5 #
2828 **
DAP only resets the master code — it does not affect any other programming.
| LED | Steady | Flashing |
|---|---|---|
| Red (left) | Output inhibited | Output inhibit paused |
| Amber (center) | Programming mode | Standby mode |
| Green (right) | Output activated | — |
To open the door with user code 2275 (example): 2275 # — one long beep indicates the door can be opened. (The # key isn't needed if programmed for auto entry mode.)
Press the egress button from inside to unlock the door and exit without using the keypad.
