Modules and relays that connect your fire alarm to other systems.

Input/output modules and relays let the fire alarm switch other equipment, such as door holders, plant shutdown or signalling, and bring inputs back to the panel. We stock 2-wire and addressable modules plus 24V DC and mains relays.

How do I choose a module?
  • Match the system: 2-wire and addressable modules are not interchangeable.
  • Inputs or outputs: check how many of each the job needs.
  • Relay rating: make sure the contacts suit the load you are switching.
