Look for data sheet which should have the original code alternatively try 5678 I have been told this is generic alarm code by some manufacturers ,
Unless you have changed the code to one you can/should remember

If the engineer or master user codes have been forgotten temporary access may be
gained by removing LK1 from the main P.C.B. The factory set codes (1234 engineer or
5678 master) may then be used to gain access to the desired function. It should be
noted that LK1 MUST be replaced before any option can be re-programmed.
