MD2400L Fire alarm control panel with star cabling I/O bus

The MD2400L, analogue addressable fire detection and fire warning system for buildings, has been designed in accordance with European Standards EN54-2:1997/A1:2006 and EN54-4:1997/A1:2002/A2:2006 and is BOSEC B-9072-FD-954 EN54-13 certified.

The MD2400L fire alarm control panel has a maximum capacity of 3 XP95 detection loops. A maximum of 126 addressable components can be connected to each loop. Communication with the conneected fire detectors and devices is based on the digital XP95 protocol.

The various components of the MD2400L fire alarm control panel are mounted in a synthetic housing with a transparent door. The MD2400L centrale processing unit includes the main processor card, up to 3 XP95 loop interface cards, the relay card with 10 relays, the system's basic power supply and the Touch screen. The front of the MD2400L fire alarm control panel is equipped with a built-in 7'' colour Touch screen for operating the control panel and for displaying the messages of the system.

The MD2400L fire alarm control panel is equipped as standard with 10 relays, of which 2 monitored outputs, 1 Fail-safe relay for "Common fault", 1 relays for "Fault power supply" and 6 freely programmable relays with potential free change-over contacts.

By means of the RS485 I/O bus and the optional module "MD2400L RS485 star wiring I/O bus", the MD2400L fire alarm control panel can be expanded with additional MD2400 operator consoles, repeater panels, printers and additional relay cards. The power supply capacity of the MD2400L fire alarm control panel must be taken into account. The RS485 I/O bus also offers the possibility to connect an MD2400 SIA modem interface and an MD2400 interface ESPA 4.4.4 protocol. 

The housing of the MD2400L fire alarm control panel offers space for two batteries with a maximum capacity of 12V 12Ah.

The MD2400L fire alarm control panel is programmed using a PC configuration software.
