Description
This article describes how to connect external alarm unit to FortiGate P-fail for monitoring any power outage.
Solution
The Buzzer connected with P-fail relay can be used for triggering alarm when the system power fails .
A Dual power supply is the supply of direct current to a unit from two outlets, which means if either supply fails, the device will keep operating as usual, and hence guarantees a constant power source for the system.
To ensure the power solution fulfills conditions where uninterrupted power is critical, the P-fail relay allows to take precautions against potential power failures.
The P-Fail, port failure or power failure, is a relay that detects the abnormal status of a power source.
Connected to an alarm unit such as a buzzer or an LED indicator, its relay circuit can be triggered as closed or open whenever the power fails.
Upon being notified by the alarm, it is possible to address the power issue before it eventually cripples the system.
Circuit is open by default and closed when either or neither of the powers is detected; the closed (or short) circuit then allows the Alarm unit to be activated.
