ARMbutton. The unit will beep, indicating a delay period (typically 30-60 seconds) before the system is fully armed. Exit the protected area during this delay. - Using the Remote: Press the
ARMbutton on the keychain remote. The unit will beep, indicating the arming delay period.
5.2 Disarming the System
You can disarm the system using either the keypad on the main unit or the keychain remote.
- Using the Keypad: Upon entering the protected area, the unit will start beeping (entry delay). Enter your 4-digit security code and press the
DISARMbutton within the delay period to prevent the alarm from sounding. - Using the Remote: Press the

The unit can be set to either an alarm sound or a chime sound, useful for monitoring entries without a full alarm.
- Refer to your unit's specific buttons or settings for switching between alarm and chime modes. This is typically a dedicated button or a sequence entered via the keypad.
5.5 Intrusion Memory
If the alarm has been triggered while you were away, the unit's intrusion memory feature will indicate this upon your return. Check the unit for a specific light or indicator that signals a past alarm event. Disarming the system will usually clear this memory.
