Visonic Powermax (433) Intruder Alarm system (Newington EH9)

Elderly, but in full working order. 6 PIR motion detectors. 2 key fobs for remote activation / deactivation. All necessary manuals etc. Motion detectors require batteries (not included). Uses 433MHz wireless signals. and is not compatible with 868MHz sensors.

IMPORTANT: the power supply is missing. It requires a 9V AC PSU, which I no longer have. (See model number label in the photograph of the back of the unit). The power needs to be hardwired to the appropriate screw terminals in the back. If you can no longer find the original part then any AC adapter meeting the specs on the label should do, you would just need to cut off the jack plug and then attach the bare wires to the terminals (top right in the photograph, labelled on the circuit board).
