Installation Manual and Administrator Guide for the SECO-LARM ENFORCER Bluetooth Access Controllers — keypad and proximity card access controllers managed entirely via the SL Access app, with no cloud or internet exposure.
Installation Manual and Administrator Guide for the SECO-LARM ENFORCER Bluetooth® Access Controllers (SK-B141-DQ, SK-B141-PQ, PR-B1124-SPQ, SK-B241-PQ) — keypad and proximity card access controllers managed entirely via the SL Access™ smartphone app, with no cloud or internet exposure.
You'll need: a drill with a 5/16" (8mm) bit plus a larger bit/hole saw for the wiring hole, a bit driver for the security screw, a Phillips screwdriver, needle-nose pliers, a smartphone with Bluetooth (iOS 11.0+ or Android 5.0+), and the free SL Access™ app from the App Store or Google Play.
Installation and wiring are the same across all models (pictured example: Single-Gang Keypad):
| Wire | Function |
|---|---|
| Red | Power (+) |
| Black | Power (–) |
| White | COM |
| Blue | N.O. fail-secure |
| Yellow | N.C. fail-safe |
| Green pair | RTE (Request to Exit) button |
| Brown pair | Door sensor |
| Orange pair | External alarm |
Important: Because the keypad/reader uses a solid-state relay, you must use the enclosed diode for DC-powered locks and the varistor (MOV) for AC-powered locks and electromagnetic locks — unless your lock has a diode/MOV built in. Failure to do so will void the warranty. Use the blue wire for fail-secure applications and yellow for fail-safe; insulate any unused wire end with electrical tape.
| Green LED | Blue LED | Red LED | |
|---|---|---|---|
| Steady | Output activated / door unlocked / toggle unlocked | Powered on, standby | Invalid access attempt / door always locked |
| Flashing | — | ADMIN settings opened (overrides other indicators) | — |
Keypad sounds: 1 beep for successful key/code/card entry (LED on for relock duration); 3 beeps + 1 flash for unsuccessful entry; 3 beeps + 1-second red/blue flashing for wrong-code lockout.
Open the SL Access app, click "Login," enter ID ADMIN (case sensitive) and factory default passcode 12345, then click Confirm. Change the default passcode immediately from the Settings page for security. Only one phone can be "remembered" as logged in at a time — logging in from another phone forgets the first.
Key settings and where to configure them:
Remain Unlocked and Remain Locked are only available to the ADMIN. The ADMIN can assign a different Output Mode to individual users, overriding the global default.
Understanding Toggle: If unlocked via Toggle, another user also set to Toggle will relock it. A user set to Timed Relock will not affect an already-unlocked Toggle state, but their entry is still logged — useful for a manager toggling a business open/closed while employees still badge in for record-keeping.
The ADMIN can set the global Output Mode to Remain Unlocked to hold a door open indefinitely (green LED indicates unlocked; only the ADMIN can relock it). Alternatively, individual users can be given a Toggle Output Mode to hold-open/relock on demand — useful for setting up a shared "Business Hours" or "Hold Open" user ID that opens at start of day and relocks at close, while other employees still use their normal Timed Relock access and get logged in the Audit Trail.
Uses a 3-axis accelerometer to detect vibration indicative of tampering. Sounds an internal buzzer (and external alarm output if connected) until the time expires or the ADMIN disables it via the app. Default sensitivity is High (smaller vibrations trigger it) — adjust to Low if experiencing false alarms depending on the mounting surface.
Unlocks the door automatically when your phone comes within a set Bluetooth range. Notes:
Defaults to the Global Output Mode, but the ADMIN can override per user with Toggle or Timed Relock (with a custom relock time of 1-1,800 seconds).
User lists can be exported/imported as CSV files (named "DeviceName_Users_YYYYMMDD_HHMM.csv") for backup or replication to another device. Importing does not overwrite existing users unless the User ID matches exactly; conflicting passcodes/proximity codes generate an error and are not merged. Large lists can be edited carefully in a spreadsheet (UTF-8 CSV format) and reimported — see the full manual for the detailed step-by-step spreadsheet procedure.
Records all events: entries, egress button presses, rejected access, door forced/propped-open alarms, tamper alarms, toggle actions, and Remain Unlocked/Locked activations. Stores the last 1,000 events (oldest overwritten once the limit is reached) — download regularly to keep a permanent record. Exported as a CSV file named "DeviceName_Audit_YYYYMMDD_HHMM.csv," searchable/filterable by user or event type, and can be deleted from the device after export.
Device settings (not user data) can be backed up to a "DeviceName_Backup.bp" file for restoration or replication to another device (Android only). Restoring pulls from the backup file matching the device's current name; to replicate settings to a different device, rename the backup file to match the target device's name before restoring.
Follow the same steps above, but continue waiting another 5 seconds after the first short beep — you'll hear 1 long beep (full reset starting), then wait for 1 short beep (reset complete). This clears the user list, audit trail, and all settings. Restore the jumper and power on as above.
| Issue | Solution |
|---|---|
| LED flashing red/blue, users can't access | Wrong-code lockout is active — wait for the timer, or ADMIN can interrupt via the app. |
| Lost ADMIN password | Use the "Resetting Only the ADMIN Passcode" procedure above. |
| Device doesn't show on home screen | Move closer to the device; exit and reopen the app. |
| Lost the ADMIN phone | Log in from another phone with the ADMIN password, then change the password immediately; remotely erase the lost phone. |
| "Log In" always shows even after logging in | Normal — Bluetooth LE doesn't maintain a permanent connection; no need to re-login while using the same device. |
| "Door forced open" shown but no forced entry occurred | Same message covers a door propped open longer than the relock time — the device can't distinguish the two cases. |
| User can't unlock the door | Verify correct User ID/passcode, that they're within their scheduled time or entry limit, and that AM/PM time settings are correct. |
