4.3. PSG3LA panel for optical and acoustic indication.
The optional panel for optical and acoustic indication compliant with the PN-EN54-16 standard indicates
the status of the entire DSO system. It is equipped with three LEDs, a sounder, and a reset button of acoustic
indication.
The panel can indicate three different operating states
CONTROL
– Normal state, indicating the presence of mains power.
ACOUSTIC INDICATION
– Fire alarm status, acoustic indication ON
FAILURE
– Fire alarm status, acoustic indication ON
The indication panel is fitted with two alarm signal inputs:
- ACOUSTIC INDICATION
- FAILURE
Inputs should be connected to the control panel or other signaling device. For proper signalization, the
terminals must be normally (without failure) opened; in the case of failure, they must be closed. A voice alarm
signal or failure indication triggers the appropriate optical and acoustic indication. The button on the front panel
allows muting the acoustic signal, while the optical signal remains unchanged. Once the failure is cleared, the
optical and acoustic indication will automatically be stopped and the green indicator will light up to indicate that the
system is operating properly.
