complicated power-hungry, hard to integrate and dark

1. Battery

the signal generator is practically only be operated with internal battery, since the thing 1.6A current pulls an alarm. which provides no Anlage.An itself is nothing against the battery in an alarm transmitter but batteries have only a limited shelf life and every couple of years is hardly possible to change high on the roof of the battery.

The detector is made meienr view just for companies, which can then be a roofer come to switch a 15 Battery ...

=> Very important to find a place where to install and remove the battery can

2. integration

This detector can be nciht with existing detectors simply parallel. if normal sirens must be switched to voltage be here "off" the voltage. This is unfortunately not always particularly nciht with the alarm system, if different detectors are in use. thus incorporating additional relay is required.

3. "Blitz"

a Blitzchen .., just to see in the dark new moon nights during a power failure the streetlights .. but nothing for the daylight => the not the point!
