AlertLatch Window Guard - safe, flexible, reliable
Escape routes via windows must be quickly accessible at all times in an emergency – at the same time, protection against unauthorized opening is essential. The AlertLatch window guard combines both: reliable security in everyday use and full functionality in an emergency.
Universal mounting & tamper-evident fastening
The AlertLatch window guard is suitable for windows or tilt-and-turn doors with left- or right-hand opening handles. A supplied cover plate reliably protects the mounting screws from unauthorized access and tampering.
ALWAYS ON STANDBY
The pre-alarm
The pre-alarm is always an essential component of the AlertLatch system and effectively reduces the workload for operating personnel. When the window handles are operated, a microswitch in the red indicator cover is activated, triggering a warning tone. This urgent, audible feedback serves as a preventative measure against the misuse of the emergency exit.
Long Life Lithium Battery
Modern battery technology
The integrated lithium battery offers a significantly longer lifespan than the commonly used 9V block batteries. This ensures an extended operating time for the window guard without maintenance requirements, thus reducing operating costs.
Standard
Battery monitoring
A sufficiently charged battery is essential to ensure the protective function and thus the preservation of your valuables. Therefore, every window guard has internal battery level monitoring. The intelligent electronics check the remaining battery capacity every 30 days. If the capacity is only sufficient for a few more weeks, an audible signal sounds at regular intervals to alert you to the low battery level.
AND ANOTHER EXTRA STANDARD WITH US
Automatic alarm shutdown
Often, a brief alarm from the window guard is enough to draw attention to the unauthorized opening of the secured window. Therefore, the intelligent electronics of the AlertLatch window guard offer an option to automatically deactivate the alarm. Users can choose between the following settings:
- Permanent alarm
- Alarm for 1 minute
- Alarm for 5 minutes.
