OK, would the following product be suitable then? https://www.securitywarehouse.co.uk/catalog/intruder-alarm-c-36/security-control-panels-c-36_102/110-input-zone-small-c-36_102_101/castle-caretech-euro-mini-inc-lcd-keypad-with-built-in-prox-p-2289.html

Hi there, I have just moved to a new house with an old Sterling 10 alarm system with 2 PIRs, it works but the keypad is very worn and I have no idea how to program it. I was thinking of getting the Euro mini keypad to replace just the keypad, see attached image with wiring. Will this work?
