GSM Red Care replacement system
GSM Terminal Use as the backup for PSTN line in the Alarm System. Phone lines can easily be cut off during storms, construction work, accidents or deliberate tampering by intruders. The result is that a burglary is possible without anyone off-site being notified. As a safeguard, many alarm systems use line-cut detection circuitry that can switch alarm reporting to a backup reporting media, which sometimes includes more than one source. Wireless media such as cellular communication are most commonly used. These media can also be used as primary communicators in places where phone lines are unavailable or unreliable Most control panels are equipped with a dialer and when a cellular (voice, data, or SMS) backup is required, there are mainly integrated cellular transmitters. This integrated cellular GSM transmitter is designed as part of the control panel to provide the backup channel should the phone line be lost or damaged. When there are PSTN network defects or problem, the system reports its status via a backup connection. External add-on cellular transmitters are typically designed to backup and report events that are being sent by the control panel to the Alarm Receiving Center (ARC) The other advantages afforded by the integrated cellular transmitter are its ability send SMS. It provide 3 input and 3 output, any short circuit impulse, it will send out an SMS to 3 chosen phone numbers.
Normal Phone line damaged or cut - alarm notification does not fail
