Fire Relays: Your Integrating Access Control of Fire Alarm Systems

Fire relays connect the fire system control panel to the power source for the locking system. Different types and configurations of fire relays exist, but their function is simple: when there is a fire alarm, the fire relay unlocks selected doors.

Fire Alarm Relays can be wireless or detector-based, among other options.

You may want your fire alarm system to take a number of automatic actions during an emergency – for example, turning off lights or closing doors. For this purpose, you will need fire alarm relays as well as devices that allow you to automate certain functions.

In an overly technical sense, a fire alarm relay is an electric switch. It distributes an amount of power to allow other devices to be powered, under certain circumstances.

 Use of Fire Alarm Relays

Typical uses for fire alarm relays include:

  • closing fire doors in an emergency (switching off the electro-magnets that hold the doors in place)
  • switching off music systems to allow fire alarms to be heard clearly
  • switching off air conditioning to prevent the circulation of air

 A fire alarm relay can control multiple relays from one relay simultaneously. They are also commonly built into devices such as fire alarm detector bases. By including the relay in the device, you are reducing the amount of wiring needed and often also saving money by having a ‘2-in-1’ device.

When choosing a relay, you need to consider the specifications of the device you are looking to control and how much power needs to be channeled. You could also consider whether you need single contact relays or dual contact relays – dual contacts may give you more flexibility in future.
