Some Key Features
Works with Any Door
Although it was initially designed for Freezers and refrigerators, the unit will easily mount on any door, wood, plastic or metal. We have customers who use the device on entrance doors to prevent them from being propped open.
Silent while the door should be open
The delay features ensures that the alarm remains silent while you are accessing supplies. This eliminates the annoyance of a constant alarm sound when it is not required.
Warns when the door has been left open
If you forget to close the door, or don't close it properly, the alarm will sound to let you know. This too is accomplished by the delay feature which determines that the door has been open too long.
Easy to install without tools
Installation is very easy and effective. Both the main unit and magnet are fastened using double sided tape. This tape is already attached to the device. You simply remove the protective film and press the alarm onto your surface. The adhesive is very strong, ensuring that it will stay attached.
User Adjustable Delay
The Standard unit has a delay, pre-set to about 5 seconds. This can be easily adjusted between 0 seconds and 21 minutes. Instructions are provided.
Loud enough for most applications
The Standard units are loud enough to be heard throughout an average 3 story house or small office. The sound pressure level is 85 db at 10cm. An industrial version is also available with a loud siren.
Long Battery life
The DA20 is now has the ability to generate a low battery warning. Due to the very low current drain, when the door is open, and no current drain when closed, the unit typically provides more than a year of service under average operating conditions. It is supplied with a 9 volt alkaline battery.

DA10-ACS AC Powered Siren Door Alarm
The DA10-ACS is an AC Powered version of our old DA10 door alarm with a Siren instead of the standard buzzer. This provides you with a system which never needs batteries changed and produces a very loud alarm sound (115 db at 1 Metre).
The AC power supply comes with a 12 foot cable and the siren comes with a 1 foot cable. Both are attached to screw terminals inside the main unit. Because there are no connectors, this improves reliability and eliminates the possibility or accidental disconnection.
The main unit and magnet can be attached using double sided tape (supplied) or fastened through screw holes. The AC power supply plugs into a standard 120 volt North American style AC outlet. The siren is attached using screws.
This system offers the same delay features and options as the standard one.
