Gardtec 300 - maintenace mode?

I need to turn the mains off for 30 mins or so but the alarm will of course go off for about 20 mins. Is there an "engineers mode" that will allow me to temporarily stop the siren when the power is off?

Many thanks

Not got a standby battery then?

Should be abt 8hrs+ of standby with a good battery, if yours goes off, it's had it.
