IPGSM-DPC Commercial Fire Communicator – Installation and Setup Guide
– 2 –
Operation
The IPGSM-DPC replaces the fire panel's POTS communications path. When an event occurs, the fire panel
goes off-hook to dial the central station. The IPGSM-DPC detects the off-hook condition and provides the
fire panel with a dial tone. When the fire panel detects the dial tone, it begins dialing the central station.
The IPGSM-DPC considers the three second period after dialing as the number dialing has been completed.
After the dialing is completed, the Dialer Capture Module returns a handshake to the fire panel.
The fire panel then sends the contact ID reports to the IPGSM-DPC, which in turn sends a kiss-off after the
report is successfully received from the fire panel. Within the IPGSM-DPC, the Dialer Capture Module
sends the contact ID reports over the ECP bus to the iGSM Communications Module. When all the reports
are sent, the fire panel goes on-hook. The IPGSM-DPC then transmits the messages to the central station
(either over the internet or the GSM network).
