Question:
The central computer cannot receive user alarm information
A:
Check if there is a short circuit or open circuit in phone line, turn off anti-theft switch on phone, and check that user host central communication programming is correct, including (central telephone number, central communication level, communication center format, user number, parameters report, etc.);
Open serial port in central software, connect serial cable correctly, check if serial port interface is damaged, check if computer is working normally. Check if center software is a trial version and check if trial version has expired by checking system log of software.
Question:
Once central computer receives alarm information, alarm information cannot be uploaded/downloaded
A:
Check if there is too much interference on telephone line, if there is a short circuit or open circuit in telephone line, and enter number correctly in central software.
Question:
Activate wired external interface after arming, but do not alarm
A:
Replace battery, relearn code between wireless interface and host, properly program protection zone attributes received by wireless interface to host, shorten distance between wireless interface and host, and consider shielding if there is a blocking metal object. Adjust installation position of wireless front end.
