As many people are starting to get rid of their home telephone service, they are in search of a cellular or gsm alarm communicator so their system can report alarms to the Central Station.
When it comes to choosing a cellular communicator, aka GSM, there are many options to choose from. The one I would like to introduce and is very popular is the Uplink 2500. This is a universal Communicator and can be used with any alarm system. There is no need trying to figure out which communicator is needed.
The Uplink 2500 cell communicator module is an alarm communicator that sends alarm data to a central monitoring station over the cellular network. The Uplink 2500 hooks into your siren terminals. Depending on what signal is being activated by the terminals, depends on what signal is sent to the central monitoring station. If a burglary signal is activated, the unit would report a burglary alarm to the monitoring station and the same goes for fire.
All GSM and Cellular Communicators usually require a service fee. This fee is typically a separate fee that is required. Some companies will offer a combined fee for monitoring and the gsm fee. Some companies will advertise monitoring for $44.99 which would include the central station monitoring and the cellular fee. When dealing with wholesalers, the fees may be separate. For example one company may charge $8.95/month for central station monitoring, but if you are using a gsm or cellular communicator, you must then also have the gsm cellular service fee. Wholesale price for that fee is typically around $12.50/month. So when you add the two together, you would get $21.45/month for central station monitoring and cellular service. $21.45 is still over 50% less than $44.99 that some companies charge.
So if shopping around and you see two fees for monitoring, do not be alarmed. Not everyone needs both services and they separate the two fees.
