Installation and Maintenance Instructions
Model G-SND Global Series Sounder
Maintaining the Sounder
EXPLOSION HAZARD: To prevent ignition of hazardous
atmosphere, disconnect the sounder from the supply circuit
before opening it. Do not open the sounder in the presence of
explosive gases in the atmosphere. Failure to follow this warning
may result in serious injury or death.
During the working life of the sounder, it should require little or no
maintenance. The non-metallic housing will resist attack by most
acids, alkalis, and chemicals and is as resistant to concentrated acids
and alkalis as most metal products. However, if abnormal or unusual
environment conditions occur due to plant damage or accident, etc.,
visual inspection of the sounder is recommended.
Cleaning the Enclosure
The enclosure should be cleaned periodically with a damp cloth to
maintain maximum sound output. Periodic checks should be made
to ensure the effectiveness of this device has not been reduced
because the sounder has become clogged with a foreign substance
or because objects have been placed in front of the sounder.
Lubricating the Threaded Joints
A silicone based, non-hardening, chemically compatible grease can
be applied if required.
Do not paint this device after installation and do not change the
factory -applied finish.
Ordering Replacement Parts and Accessories
A replacement part for the driver/PCB assembly and accessories
are listed in Tables 2 and 3 on page 28. Due to certification, certain
component parts are not available for field replacement. Sounders
with this type of damage must be either replaced entirely or returned
to Federal Signal for service. Refer to instruction manual 25500259 for
accessory and replacement part assembly and operating instructions.
