The IPGSM-COM from Honeywell Power Products is a UL-listed primary fire alarm communicator that provides Contact ID reporting via IP or GSM cellular pathways. Using the Honeywell AlarmNet communications network, triple-path redundancy provides superior connectivity for life safety systems. An IP path is used for primary communications and GPRS GSM cellular for back-up. Should GPRS become unavailable, the unit switches over to SMS communications.
