In order to gain easy access to your home, burglars will first try your door to see if it is unlocked. With this product protecting you, as soon as they touch the doorknob, this alarm will sound off alerting you to their attempt at entry.
This entry alarm utilizes dual-sensing technology to enable it to protect both metal & wooden doors. For wooden doors with metal knobs, the touch sensor will detect a person touching the outside doorknob and will instantly emit a loud 110 dB alarm to scare him away and alert you to the attempted entry.
Even if he is wearing gloves, the Pro-Tec-Door Entry Alarm will sound as soon as the outside knob is touched. For metal barriers or those with wooden or plastic knobs, the vibration sensor will detect the attempted forced entry. You can use the chime mode at home to notify you of visitors or in a business to announce customers.
In Chime mode, activating the unit will cause the chime to sound twice and the unit will reset itself in 30 seconds.
In Alarm mode, it will sound continuously for 60 seconds and rearm itself after a 6-second delay.
Low Battery Warning: The three (3) AAA batteries can last approximately 1500 hours in standby mode. If the batteries are running low, a beeping sound will indicate it is time to change the batteries.
