Fire alarm control panel

The ACSP-402 fire alarm control panel is designed to:

  • monitor operation of automatic and manual call points,
  • control sirens,
  • control devices used to transmit fire alarms and failure signals
  • control the operation of fire protection devices or systems,
  • monitor the operation of fire protection devices or systems,
  • monitor the operation of other external devices,
  • control other external devices

These features make it possible to detect a fire at its earlies stage and alert the users of the building with acoustic and/or optical signals as well as notify relevant services. This in turn allows one to quickly commence fire-fighting activities. The control panel can also automatically activate fire protection devices.


System structure

  • support for up to 256 zones
  • support for up to 32 groups
  • possibility to create interlinks between zones, sub-zones and groups
  • support for up to 256 call points (detectors / MCPs)
  • support for addressable detection circuits of the following types:
    • loop (up to 2 circuits)
    • radial line (up to 4 circuits)
    • loop with a side line / side lines
  • support for a printer
  • extensive functions for testing the control panel and system


  • 4 programmable inputs on the control panel mainboard (NO, NC)
  • monitoring of external devices status, e.g. for reporting fire alarms and failures


  • 2 control outputs for conventional sirens
