Visonic Wireless Alarm Frequencies - 868-1 vs 868-1:012

[Raven24]

Hi.
I've a Visonic wireless alarm system. The existing wireless PIR sensors are all marked 868-1:012. I'd like to add some more sensors, and I've found some that are listed as 868-1.
Are these likely to be compatible with my system?
Thanks for any help

Although all the devices look the same, Visonic did make some for those who had enough money that were on a slightly different frequency, it was their way of stopping you from getting another alarm company to add devices to your system. I do not have the frequencies to hand, so my only suggestion would be, buy ONE of the new devices and see will it "Learn" to your system.

iirc there are only 2 frequency versions, 433 & 868mhz
