    DMP also has recently received approval for GSM only fire communication for the XR500/463G combo. (the XR500 can be used as a Slave Communicator for any Fire Panel) with three technologies; Dialer, GSM, IP and you can combine those three technologies just about anyway you like.

    DMP has both a GSM communicator approved for Fire Communication (the exception is that FDNY has not approved any single technology) however as Sascha states, NFPA approves GSM with a five minute fail time.

    DMP also has a 900Mhz Premises Wireless, the 1100 Series that is Commercial Fire rated and listed to UL864 for Commercial Fire Smoke Detectors, Universal Transmitters for Pull Stations and even a Wireless PIV & Os&Y. Plus a suite of receivers or repeaters that has an open air range of 1.7 miles. Trench your last parking lot...with a wireless PIV!

    This all depends on the listing of the device.  NFPA 72 2010 edition allows the use of cellular communicators to be used as a sole communicator with a five minuet supervision window.  DSC makes a GSM radio GS3055 ICF that has UL864 as a sole fire communicator and has CFSM.  This module will send full reporting of any fire panel that uses the Contact ID format or has four inputs.

    AES has a totally wireless solution from the subscriber’s premise to the Central Station. It is NFPA-72 9th edition compliant for just this purpose.  HOWEVER, you should get the local AHJ’s blessing as well!

    It all depends on what type of Wireless Communications device is used. With some forms a Second type of communications IS required. If a Wireless Communications is UL Listed as a PRIMARY form of communications- It requires no secondary device.

    AES Intellinet is one of the wireless communicators listed as Primary by UL

    AES-IntelliNet has had a NFPA Compliant / UL Listed wireless solution for standalone commercial fire alarm transmission since 1996.
