The frequency of fire alarm testing can vary depending on the jurisdiction and the type of building. However, there are some common guidelines that are often followed:

1. **Weekly Testing**: It is recommended to test the fire alarm system weekly. This typically involves activating a manual call point (break glass unit) to ensure that the alarm sounds and that the alarm fire alarm testing frequency signals are transmitted to the monitoring station if applicable.

2. **Monthly Testing**: Some regulations require additional monthly testing of specific devices, such as smoke detectors or heat detectors. During these tests, individual devices are checked to ensure they are functioning correctly.

3. **Annual Inspection**: A more comprehensive inspection and testing of the fire alarm system is typically required on an annual basis. This includes testing all devices, checking the control panel, and ensuring that the system is in compliance with all applicable regulations.

4. **Additional Testing**: In addition to weekly, monthly, and annual testing, there may be other testing requirements based on specific regulations or the type of building. For example, some buildings may require semi-annual testing or testing after any significant modifications to the fire alarm system.

It's important to note that these are general guidelines and that the specific requirements for fire alarm testing may vary depending on the jurisdiction and the type of building. Building owners and managers should consult with local fire safety authorities or a qualified fire safety professional to determine the specific testing requirements for their building.
