Running on a single 9V battery, and using a designed in tilt sensor, Protectrix™ detects when the garage door is open
When the garage door is open for too long (variable 1 minute to 4 hours), Protectrix™ sets off a Beep and a flash.
If the garage door is not closed before the alarm ends (30 seconds), Protectrix™ sends a signal to your garage door
opener to close the garage (the signal sent is the same as the signal sent from your garage door remote control)
Features:
Requires NO wiring, and installs in only 5 minutes.
Can be easily disabled by turning the DELAY setting to Off.
DELAY settings from 1 minute to 4 hours.
Works with all existing sensors in your garage, such as the beam and force sensors built into most
garage door openers.
Alarm periodically beeps and flashes when battery is low.
