Federal Signal G-SND Instructions page 12

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 environmental 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 that 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 - 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. 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. To order, call Federal Signal Customer Support at 708-534-4756 or 877-289-
