Maintenance and Testing
Employee alarm systems are important life safety devices and must be maintained in an operating condition at all times except during repairs or maintenance.

Test the reliability and adequacy of non-supervised employee alarm systems every two months.
Routine Test and Maintenance
- Use a different actuation device in each test of a multi-actuation device system.
- Maintain or replace power supplies as often as necessary to ensure a fully operational condition.
- Provide a back-up means of alarm when systems are out of service, such as employee runners or telephones.
- Use properly trained persons to service, maintain, and test employee alarms.
- Do a visual check to ensure employee alarm devices are not obstructed/installed in a manner which would prevent sound or light from reaching or entering the protected areas.
- Restore all employee alarm systems to normal operating condition as soon as possible after each test or alarm.
- Spare alarm devices and components must be readily available in sufficient quantities and locations for prompt restoration of the system.
