I have an alarm system in separate building. When the smoke detector detects smoke or fire.. the mother unit will ring my cell and text me... I need a device where it constantly sends ping to the remote location and the remote location pings my device every 15 seconds.. this is to ensure there is always open communication between the remote site and me.. and then when the smoke detector and alarm triggers.. I want it to send the signal directly to my device... what kind of equipment must I look for? Thank you.
