Sounder Booster
Features
The Advanced 4A Sounder Booster (Mxp-026) is a peripheral unit that takes a standard sounder circuit from
either a control panel or other panel based sounder circuit controller and provides increased sounder output
capability.
This boosted output is fully monitored for open and short circuits and will take an independent supply to
provide up to 4 Amps of sounder drive current to a single circuit.
On board indication via 2 LED indicators located on the booster PCB enable the user to view when an output
has been triggered and when an external power supply has been connected
Features
The unit is available in 2 formats:
The Mxp-026 is a booster card only for mounting in a customer’s / OEM enclosure or within an MxPro
4 multi-loop panel.
The Mxp-026-BXP is a booster card and a 5 Amp EN54-4 power supply mounted together in a metal
enclosure.

Specifications & Ordering:
Models, Sales Order Parts:
Mxp-026-BXP : 4A Sounder Card Boxed with 5A PSU
Mxp-026 : 4A Sounder Booster Card (Requires a minimum 4 Amp power supply and enclosure)
Applications / Limitations:
The sounder booster is used where a single sounder output circuit of up to 4 Amps is required.
Each of the panel’s sounder outputs can only monitor a single circuit. The unit must therefore be situated at the
end of the panel’s sounder output circuit to maintain correct fault monitoring. ‘Daisy-chaining’ is not
recommended, as this would require the monitoring of more than one circuit. See ‘wiring configuration’
Compatibility:
The Mxp-026 is compatible with all MxPro 4 control panels.

1 Wiring Configuration
The diagram below shows a ‘typical’ application for the 4A sounder booster. Note that a 10KΩ EOL resistor
must be fitted to the end of the boosted sounder output circuit to maintain correct fault monitoring.
Mxp-026 Wiring Configuration.
Note. PSU ‘Failsafe’ Operation
The EN54 PSU shall be fitted with a ‘Fault’ relay that is energised during normal operation and de-energised for
any fault condition. The ‘FAULT I/P’ connections on the sounder booster card should be connected to the ‘COM’
and ‘N/O’ connections of the PSU as shown above. The table below indicates the state of the relay for all
conditions.

2 Fault Indication
Any open circuit condition between the ‘FAULT I/P’ terminals will result in the panel indicating a ‘Sounder Open
Circuit’ fault. When the ‘FAULT I/P’ terminals are connected to the PSU’s ‘Fault’ relay, the panel will indicate a
‘Sounder Open Circuit’ fault should the PSU develop any fault.
Normal sounder circuit open circuit and short circuit monitoring is applicable on the boosted sounder output
circuit.
