following tones: 4, 5, 6, 9, 12, 14, 22 and 28. The switch in ON position –maximum volume

3. Maintenance
The fire alarm system elements require regular maintenance. The periodic checks of the
SPP-110 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 fire alarm control panel manuals to find out how to start the test.
