Is it possible to have two of your sirens linked to one panic button or sensor?

Short answer: Yes.

You can link each of our SK6 sensors and remote controls with as many receivers (dialers, alerts, and sirens) as you want.

But there is a limit to the number of sensors and remote controls that a dialer, alert, or siren can be linked with. 

For example

• The SK619 remote control can be linked with an unlimited number of receivers; but
• The SK618 dialer can be linked with up to 15 sensors and 8 remotes.
