24hr is the tamper loop, So wiring problem, open box, that would trigger tamper. But as already trigered. Each sensor goes back to its own set of contacts. Except for the tamper loop, when you figure out the tamper loop, short it out, HOLD the spring on the switch in, That is also anti tamper. reset system, that should clear it. IF not problem at bell box end, But again tamper circuit. If that stopped it, Check connections from termination points for each sensor, short out each sensor in turn. When you find the sensor, fix or replace it, Same if bell box, open up have a look, check wiring and switch, if ok check wiring, etc
