Advanced MXS-503-PCB Spare MX-5400 Basecard PCB only – No Loop Cards – Programmed

FAQs

What is the difference between Gen 1 and Gen 2 basecards?

Generation 1 (Gen 1) basecards had the power supply unit (PSU) integrated into the circuit board and were not mounted on a chassis plate. Generation 2 (Gen 2) basecards like the MXS-503-PCB feature a separate PSU from the basecard for easier modular replacement, and the basecard is mounted on a chassis plate. This modular design allows you to replace just the PCB or just the PSU if only one component is faulty, reducing replacement costs.

Do I need to purchase a PSU separately?

Yes, the MXS-503-PCB is a PCB-only option. If you need to replace both the circuit board and power supply, you should order the complete assembly (MXS-503-CP) which includes both the PCB mounted on a chassis plate with the PSU. If your existing PSU is working correctly, the MXS-503-PCB allows you to replace only the faulty PCB. The corresponding PSU for this basecard is the MXS-503-PSU (5A rating).

How many loops does this basecard support?

The MXS-503-PCB supports up to 4 detection loops, making it suitable for large fire alarm installations requiring multiple zones of coverage. This is the basecard for the MxPro 5400 model, which is Advanced’s 4-loop panel configuration. Loop driver cards must be installed separately to activate each loop.

What detector protocols are compatible with this basecard?

The MXS-503-PCB is supplied pre-programmed with Apollo/Hochiki protocol as standard. It can be reflashed to support other protocols including Argus (Vega), Nittan (Evolution), and Axis EN. When used with MXP-568 loop driver cards, it supports Apollo (XP95, Discovery), Hochiki (ESP), Argus (Vega), and Axis EN detectors. For Nittan Evolution protocol, you would need MXP-567 loop driver cards.

Can I use this to replace a Gen 1 basecard?

Yes, but you will need to order the complete Gen 2 chassis plate assembly with mounted PCB and PSU rather than just the PCB-only option. For Gen 1 to Gen 2 replacements, order the MXS-503-CP (complete basecard with large chassis) or MXS-503-CP-E (complete basecard with extended chassis) depending on your enclosure type. These include the chassis plate, PCB, and PSU needed for the conversion.

What chassis size does this PCB fit?

The MXS-503-PCB is designed for large chassis configurations. It is used in MxPro 5400 panels which utilize large enclosures. If you have an extended enclosure configuration (such as for 8-loop systems), the equivalent extended chassis option would be required. Always verify your existing chassis type before ordering replacement PCBs.

Is this PCB supplied programmed?

Yes, the MXS-503-PCB is supplied pre-programmed and ready for installation. It comes with Apollo/Hochiki protocol as standard. If you require a different protocol (Argus, Nittan, or Axis EN), you can reflash the basecard using Advanced’s programming tools and software.

What loop cards do I need with this basecard?

The MXS-503-PCB requires separate loop driver cards to be installed for each active detection loop. For Apollo, Hochiki, Argus, and Axis EN protocols, use the MXP-568 standard loop driver card. For Nittan Evolution protocol, use the MXP-567 loop driver card. Each loop requires its own driver card, so for a 4-loop system you would need four loop driver cards.

Can I replace just the PCB if my PSU is still working?

Yes, that’s exactly what the MXS-503-PCB is designed for. The Gen 2 modular design allows you to replace just the PCB if the power supply is still functioning correctly, or just the PSU (MXS-503-PSU) if the PCB is working. This reduces replacement costs and spare parts inventory requirements compared to Gen 1 systems where the entire integrated assembly had to be replaced.

What spares kit should I order for this panel?

For MxPro 5000 series control panels, Advanced offers the MXS-518 spares kit which contains essential replacement components and accessories. For specific basecard spares, you may want to stock the MXS-503-PCB (PCB only) and MXS-503-PSU (PSU only) to cover both potential failure modes. Consult with your Advanced distributor or maintenance contract provider for recommended spares inventory based on your installation size.
