securitywarehouse Posted November 2, 2010 Posted November 2, 2010 I have fitted new detector after false alarms. This detector is fine now but other 3 out of 7 are now giving false alarms but these 3 were ok before i fitted the new one. Should I replace other 3 or does this suggest that the new one is not compatible or there is another fault in the system? System is approx 3 yrs old. Quote
