Fortress Security Store (TM) GSM-B Wireless Cellular GSM Home Security Alarm System DIY Kit with Auto Dial

The Fortress GSM-B allows you to install a full-scale monitored alarm in your home without incurring costly monthly fees. A totally wireless system, the main console monitors the remote sensors (see below) and triggers the alarm in case of an intrusion. At the same time, it'll send a text message or call you to notify you of a potential break-in. Enter 6 numbers to dial in case the first isn't answered, and 3 SMS numbers. Text feature requires use of a SIM card.

The GSM-B has both landline and GMS capabilities, allowing one as a backup. In case an intruder manages to cut your landline, the system will still function with the GSM dialer. Furthermore, the alarm will automatically sound if the landline is forcibly cut and the system is armed.

Dial in to arm or disarm the system, check the status or use the built-in intercom. This allows you to talk to anyone near the main console. Intercom feature requires use of a SIM card.

Includes

* 1 X Main Console
* 10 X Window/Door Contacts
* 3 X Passive infrared motion detectors
* 3 X Remote control keyfobs
* 1 X Loud indoor siren
* 1 X Loud outdoor siren
* 1 X Panic Button

Why is that?

its the frequency that they operate on 433 very congested you want the 868mhz i think it is a lot better

Why is that?

"The 868MHz band is less congested than 433MHz. On 433MHz your signal is competing in a total free-for-all of alarms, controls, telephony and all-sorts - competition which can lead to your control signal being wiped out or distorted. 

There's another feature of 868MHz that really helps control interference too - its called "limited duty cycle". This means that no device using the 868MHz frequency band is allowed to transmit for more than a few milliseconds every second - so there are far fewer devices transmitting at any one time. According to one of the manufacturers who make the transmitter chips for 868MHz, the frequency has at least 100 times more "interference immunity"." found online

I see, thanks. That's really helpful information. This alarm system seems to have good reviews on Amazon, though. Any similarly priced alarm system at 868MHz that you know of?

you want a alarm thats already pre linked it saves a lot less hastle i got a very small alarm on 868mhz and you can get a external siren have a look for cnm on the bay for 70 comes with a dialler pop a sim in and it calls you just a basic alarm imo a i have 1 good value

thanks 433mhz not my cuppa

I think this needs a Sim as it has a GSM dialler. Can anyone recommend a Sim that stays active with barely any use?

This is american market alarm different regs from uk, it wont have any grading and highly unlikely to get accepted by insurer

The clowns at Vectone have a GBP1 SIM at the moment, but be warned it comes with really shocking customer disservice.
