PWR20
The PWR20 is used as an extra power supply when the power resources of the control panel is insufficient. It is recommended to wire all modules, detectors to PWR20 if they are installed in unprotected premises. Intentional damage of the said components or shortening of the power/data bus wires will not interfere with the operation of the rest of the alarm system.
