4. Maintenance
The fire alarm system elements require regular maintenance. The periodic checks of the
SPP-400 sounder should be carried out at least every 6 months. In spaces where working
conditions are difficult (e.g. dust, aggressive environment that may cause corrosion, etc.), the
periodic checks should be carried out more often.
As part of maintenance, start a test in the control panel and make sure the acoustic signaling
is working. Please go to the ACSP-402 control panel manuals to find out how to start the test.
Start of the test and test activation of devices will be registered in the control panel event log.
During the test, make sure the device is in its right place (e.g. it has not been swapped with
another device).
