Local Quiet Test
The Local Quiet test allows performing Quiet Tests on the siren control and siren speaker
array. Quiet Test uses a 20 kHz tone to quietly test the tone generators, amplifiers, and
speaker drivers. To perform this test, program the Quiet Test under one of the activation
codes. If it is one of the first 7 codes, activate it manually through the switches on
the front panel or with the remote activation inputs. Normally once the Quiet Test is
programmed under one of the activation codes, the code is activated over the radio
channel, the panel switches or with a local laptop computer running the Commander
Software System.
Operation
Obtain the results of a Quiet Test remotely using the printout or Commander.
Obtain the status locally at the siren site with a portable computer running Commander.
The actual amplifier voltage and current are monitored with Quiet Test providing a true
indication of each amplifier and load performance.
Finding Faults
When using Commander, the controller automatically updates the Quiet Test status each
time a new Quiet Test is run. Obtain the status from the status detail screen and from the
Reports menu.
