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
  • control output for fire alarm transmission devices
  • control output for fault signal transmission devices
  • 8 programmable relay outputs
    • control of external devices
    • output for controlling automatic fire protection equipment
  • 24 V DC power supply output
  • dedicated power supply output for ACSP-ETH and ACSP-RSI modules
  • signal delay at outputs

RS-485 communication buses

  • 2 bus ports for connecting
    • APSP-402 repeater panel
    • ACSP-ETH module (for extending the control panel with an Ethernet port)
    • ACSP-RSI module (for opto-isolation of the bus and connection of a printer)

E-mail notification (requires connecting the ACSP-ETH module)

  • 4 addresses for notification
  • selection of event types for notification
  • periodic diagnostic reports

Setting up

  • setting up with keys on the front panel of the control panel
  • free ACSP Soft programme for configuring the control panel (USB port)

Event memory

  • non-volatile memory for up to 9999 fire alarms
  • non-volatile memory for 8999 events (including fire alarms)

Control panel mainboard module

  • LEDs for signalling the status of the control panel and external devices
  • LCD display for:
    • setting up the control panel
    • presenting information about fire alarm
    • presenting information about disablement, test or failure conditions
    • viewing the list of current disablement, test or failure conditions
    • viewing the history of alarms and other events
  • USB port to connect a computer
  • power supply connection
  • battery connection
  • built-in piezo transducer for acoustic signalling
  • real-time clock with battery back-up power

Power supply

  • switching mode power supply APS-318 with short circuit protection
  • automatic switching to back-up power supply (battery) in case of failure of the main power supply
  • battery charging circuit with temperature-compensated charging voltage
  • monitoring of the battery status and disconnection of a flat battery
