Pre-Operation Checkout
After the siren has been completely installed, perform the following checks before putting
the siren into service.
The output sound level of a siren is capable of causing severe hearing
discomfort or permanent hearing damage. Therefore, ALWAYS wear
appropriate hearing protection when performing tests or maintenance on the
siren, and post warnings to warn people before they are exposed to excessive
sound pressure levels.
1. Make sure all connections in the Control/Battery Cabinets are correct and properly
tightened.
2. Activate wail on the control panel. Check for proper sound output and siren tone.
3. After the installation is complete and it has been established that the siren is
operating properly, Federal Signal recommends that all control devices be padlocked
to discourage tampering and vandalism.
Maintenance
Service or maintenance should be performed by qualied personnel familiar
with the siren, associated controls, and power sources being used.
The sound output of the siren is capable of causing permanent hearing
damage. Use adequate hearing protection and avoid excessive exposure.
Before servicing or maintaining, ensure that remote activation cannot occur
and disconnect power to the siren and its controls.
The output level of a Modulator Series Siren is capable of causing permanent
hearing damage. Therefore, ALWAYS wear hearing protection when performing
tests or maintenance on the siren.
To prevent the siren from sounding always turn off the power to the siren at
the disconnect switch and remove any DC power being supplied by the battery
box before inspecting or maintaining the siren.
Test the siren for proper operation at least once a month. A daily test at noon, curfew, or
other selected time is preferred. This not only enhances the usefulness of the siren and
veries that it remains ready for use in an emergency, but also instills public condence
in the reliability of the warning system.
In order to minimize the possibility of siren failure, annual inspection and maintenance is
desirable.
Perform a driver inspection as described in the next section.
