When it comes to fire safety in commercial and residential buildings, understanding the integration between fire alarm systems and sprinkler systems is essential. These systems work together to ensure a rapid and coordinated response in the event of a fire. The connection between the fire alarm and sprinkler system is not just a regulatory requirement but also a crucial aspect of comprehensive fire protection.

The Purpose of Sprinkler and Fire Alarm System Integration

Fire sprinkler systems are designed to suppress or control a fire until emergency responders arrive, reducing the risk of loss of life and limiting property damage. However, sprinkler systems alone cannot alert building occupants or emergency services. That’s where fire alarm systems come in. By integrating the two systems, a building’s occupants receive immediate alerts when the sprinkler system activates, and the monitoring station is notified and will dispatch fire department/emergency services.

Understanding Waterflow and Tamper Switches

To better understand how and why the fire alarm system is tied into the sprinkler system, it’s helpful to learn more about the role of waterflow switches and tamper switches.

  • Waterflow Switch: a device that detects movement of water and reports this action to a fire alarm control panel. There are several types of waterflow switches in the industry, but the most common is a paddle or vane type device. These types of devices are typically designed with a delay of 30-90 seconds. Because water pressure can fluctuate, a delay helps prevent nuisance (false) alarms.
  • Tamper Switch: devices the monitor the status of water-based systems control valves. These are important to have on your system to ensure that you always have supply water to your system and indicate to you if and when anyone attempts to shut or tamper with system control valves.

Why Integration Matters

The integration of fire alarm and sprinkler systems serves several critical purposes. First and foremost, it enhances safety and emergency response. When a fire occurs, the sprinkler system suppresses the flames while the fire alarm system notifies building occupants and emergency services. This dual action helps significantly reduce the potential for injury or death.

Additionally, having these systems tied together ensures compliance with building codes and fire safety regulations. The National Fire Protection Association (NFPA) and local building authorities may require that sprinkler and fire alarm systems be interconnected to maximize safety.  Speak with an AHJ or your Fire Protection Specialist to ensure your building and systems are up to national and local codes.

Integrating these systems along with regular inspections and maintenance can also help verify your system is working as intended in case of emergency event. For example, if the tamper switch gets wet or damaged, or if someone tries to tamper/interfere with device, a supervisory or trouble signal will be displayed on your fire alarm control panel.

Preventing Common Issues

While having a connected system offers many advantages, it also requires careful maintenance to function properly. For instance, false alarms can occur if the waterflow switch is too sensitive or if there are sudden changes in water pressure. Regular testing of waterflow and tamper switches help prevent these issues and ensure that the system only activates in genuine emergencies.

Building owners should work closely with certified fire safety professionals to maintain their systems and follow NFPA and Local codes. These experts will test to NFPA 25 standards to ensure working order of your fire protection needs. Monthly, quarterly, and semi-annual inspections will identify any deficiencies that may present themselves at the time of inspection. Building owners or owner representatives should still conduct regular visual inspections to identify any issues and address them immediately. These regular inspections and tests will keep your system in working order.
