| Door Sensor | Connect to optional N.C. sensor (e.g. magnetic contact); ground if unused |
| Output 1 Inhibit / Interlock Control | Connect to matching terminal on a second keypad for interlock operation |
| Tamper N.C. | N.C. contact, max 50mA @ 24VDC — connect to alarm's 24-hour protection zone |
IF USING THE KEYPAD WITH A MECHANICALLY OPERATED DOOR OR GATE, MOUNT THE KEYPAD AT LEAST 15' (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.
For a new master code, a single 4-digit user code for all users (no proximity cards), one output to unlock a door, and a 3-second delay:
A flashing amber LED indicates standby mode; a solid amber LED indicates programming mode.
| Function | Purpose | Default |
|---|---|---|
| 01 | Master programming code | 0000 (4–8 digits) |
| 02 | Super user code | No default — must be set |
| 03–05 | Common user codes for outputs #1–#3 | No default |
| 10 / 20 / 30 | User codes/cards for outputs #1/#2/#3 | No default |
| 40 | Visitor codes for output #1 | No default |
| 41–43 | Duress codes for outputs #1–#3 | No default |
| 51–53 | Output mode/timing for outputs #1–#3 | 5-second momentary output |
| 55 | Real-time clock | No default |
| 56 | Output #1 auto-disable time | No default |
| 60 | Wrong-code system lock-up | Locks after 10 false tries |
| 70 | User code entry mode | Manual entry (# key required) |
| 71–73 | Keypad sounds, output relay sounds, amber LED flashing | All enabled |
| 80–91 | Door-forced-open, door-propped-open, door open alarm, egress delay/warning | All disabled/immediate |
The Direct Access to Programming (DAP) code 2828 and the system restore code 9999 are fixed and cannot be changed.
Duress codes allow a user to trigger a silent alarm while appearing to unlock the door normally. If a user enters a duress code instead of their normal code, outputs activate as usual, but the duress output simultaneously activates. A duress code cannot deactivate the duress output — only a normal user code/card, super user code, or master programming code can. Duress codes cannot be the same as any other user code (e.g., subtract 1 from the last digit of a real user code).
DAP does not reset any other programming — for a full reset, use System Restore (code 9999 while in programming mode).
| Issue | Solution |
|---|---|
| User code doesn't work | Make sure you programmed a User Code, not a Super User or Common User Code. Try deleting super/common user codes and reprogramming. |
| Master programming code doesn't work | Use the DAP process to reset it. |
| Keypad constantly beeps on power-up | Normal operation — press 12# to stop the beeping early. |
