Scantronic I-on16 alarm - wireless range?

[jonny_bravo]

Been researching wireless alarms,. The Scantronic gets very good reviews. Does anyone have first hand experience of how the range deteriorates when going thru walls etc?

From where I would intend on mounting the control unit there would be a single brick wall, then 15m distance before reaching the garage (sectional concrete job with up and over door)

Seems that 100m range is the norm in free space .

Thanks in advance.
