Envisalink Alarm and 2 Routers


I have just installed my HA yesterday and still trying to figure to some issues.

My network configuration consists on the Cable company modem/router, the I have an Apple Time Capsule that I use as my Network’s router where everything is connected to.

My Envisalink alarm is connected to the Cable company’s router because if I connect it to the Time Capsule, the alarm does not connect to the Envisalink service.

Since the alarm is in a different network from the raspberry, Home Assistant does not find the alarm. How can I configure this to work?

I don’t have much experience with networks so please bear with me. Thank you!
