If you hear an alarm sounding twice, it is possible that the door has not been closed fully, and the Mortise is unable to lock properly. Try again but if the warning sound continues, it signals to reinstall or adjust the position of the door lock.

Make sure that you are using the recommended batteries and do a bolt tongue test, to see if the motor is still working correctly.

If it is still not working and the alarm is sounding, please reach out to us at support@igloohome.co for further guidance.
