I'm not sure of your question. NextAlarm is the monitoring service or CS (Central Station). All you need to do is tell them you have an ELK M1 Gold, you tell them what zones are what and what you want them to do when they receive a CID signal. For example Zone 1 is the Front Door, it is an exterior delay door, when you receive an alarm signal from Zone 1, call the police, call me at work, and send me a text message to my cell phone. Another example, on school days, if little Johnny hasn't disarmed the system by 3:30 p.m. then send me an email, and a text message to my cell phone.
