Wired seismic detector with an additional shock sensor
The siren has a sealed battery that powers the device. The battery charges from the Fibra line and is used both for indication and for notifying about alarms and events.
If the Fibra line is damaged or there’s an emergency power shortage, the backup battery will provide the siren with power to indicate and alert alarms and events.
In the Ajax apps, you can set the siren to activate an alarm if the Fibra line is damaged.
Fibra devices are connected using a 4-wire cable.
We recommend using the following types of conductors:
U/UTP cat.5 4×2×0.51 mm (24 AWG) cable, copper conductor.
4×0.22 mm² signal cable, copper conductor.
The maximum length of a Fibra line is 2,000 meters.
However, the appropriate length for the wired line depends on the number and type of connected devices and the type of used cable.
Therefore, before installing wired devices, we recommend calculating the line length using an online calculator.
After installation, perform a Fibra signal strength test and a Lines power test to make sure the system functions properly.
