Hello,
I have just installed a new Pyronix Deltabell plus and a new battery for the alarm panel. (Citydell XR2)
As soon as I power it up from either the mains or connecting the battery it goes straight into tamper mode. (Even if the tamper spring is depressed)
I can then input my code to silence the alarm, but after this the keypad goes dead.
I cannot get it out of tamper mode and none of the keys make a noise when pressed like they usually do !
I’ve checked the tamper on the deltabell plus and the cover is definitely pressing the switch down.
Any advice ?
