The Duet4 is an advanced auto-dialling digital communication device for adding GPRS, GSM, SMS and LAN reporting to control panels that have a telephone line connection.

The Duet4 monitors the telephone line that is normally connected to the control panel’s PSTN connection. If a line fault is detected, the Duet4 sends a line fault alarm to the Alarm Receiving Centre on its radio or LAN path. Any subsequent alarm transmission from the control panel is then sent to the ARC via one of the Duet4 paths. In addition alarms can also be sent by SMS text to mobile phones. The Duet4 can be used as the primary or secondary path for alarm transmission but will be the main path for test calls. The Duet4 has 4 trigger inputs that can be activated independently. The Duet4 continuously monitors the radio path. If a radio path fault is detected, the Duet4 allows the control panel to dial out on the PSTN network and sends a radio fault alarm to the ARC on the LAN path (if available). The Duet4 D2660 can operate with control panels using DTMF Fast Format, Contact ID and SIA alarm reporting protocols, and can download to most panels via GSM. The Duet4 will require a GSM SIM card that is enabled for ‘GPRS, GSM data and SMS’ operation. The Duet4 is semi-housed in an ABS plastic case which protects the electronics and meets PSTN safety requirements. The Duet4 includes 4 outputs that can be controlled from the associated downloader or by sending SMS messages to the unit from a PC or mobile phone. Up/downloading telephone calls to the control panel via PSTN are unaffected by the Duet4.
