Integra 14/32/64/128/256
As a colleague mentioned the number of inputs and outputs
In a control panel, say for a house, it's a minimum of Integra 32 (on board 8 inputs and expand with another 8 inputs/outputs with expanders (for clarity there are input and output expanders).
So you need say 12 inputs (each motion detector takes one line) to secure your house with motion detectors only, but you have an entry gate with operator and a garage also with operator (for remote controls).
So you need outputs in the control panel to control the entrance gate and the garage door.... and I'll mention that let's say you fancy anti-burglary roller shutters also controlled remotely (button/pilot).
And you can do dependencies e.g. if you arm the alarm all the roller shutters close. You can add sprinklers on the property so that the grass is watered regularly at certain times (or even just when it's hot). The more inputs/outputs you have the more you can come up with different relationships. It's like programming only in a bigger way. Even exterior house lights can be controlled at set times. Power sockets, different switches. I don't think there is a limit to the number of inputs and outputs.
I think the Satel integra 64 or 128 is a bit too much, but it is an investment for years and the possibilities ... are great.
I would like to suggest that there is also Integra 128 WRL, but you should read what and how on the manufacturer's website SATEL
Of course, Integra 32 has 8 inputs/Integra 64 has 16 inputs/Integra 128 has 16 inputs/Integra WRL has 8 inputs (it does not have a dialer which is usually used by a security company to notify about events from the alarm system), but you add further inputs via expanders up to the number of inputs supported by the selected control panel.
There are also wireless cable flood detectors, smoke detectors, external and internal motion detectors, reed switches, breakage detectors, vibration detectors, two-way communication remote controls, etc..... you could go on and on. Why Satel is simple for the user. And the support they have is very good.
Of course there are other companies .... But I won't comment on that.
