Brings an existing Honeywell/ADEMCO VISTA panel onto Alarm.com without replacing it. The customer keeps the panel, the keypads and every device already wired to it, and gains app control, remote access and notifications. On a takeover that is the difference between a module sale and a full system replacement the customer will not authorise.
Built for the alarm installer
It lands on the keypad bus with two data connections plus 12V and ground, so the install is a handful of terminations inside the existing can rather than a rewire. Z-Wave Plus support is built in, which means locks, lighting and thermostats can be added later without another controller on the wall.
One thing to program correctly: the SEM must be the sole communication path for alarm signaling. It is not compatible with the panel continuing to report over POTS, so the phone line reporting comes out of the programming as part of the job.
This variant reports over AT&T 4G LTE-M with 3G HSPA and 2G GSM fallback.
Key features
- Keeps the existing panel and devices, turning a replacement conversation into a module sale
- Connects on the keypad bus, so the install is terminations rather than a rewire
- Z-Wave Plus built in for locks, lighting and thermostats with no extra controller
- AT&T coverage with dual-path Ethernet available alongside cellular
- Rated 14F to 131F, which covers unconditioned utility spaces and garages
System requirements
Requires a compatible Honeywell/ADEMCO VISTA panel (10P, 15P, 20P or 21iP, 2005 or later, v3.1+) and 12V from the panel. The SEM must be the sole alarm signaling path; POTS reporting must be removed. Ethernet is optional for dual-path.
Can the panel keep its POTS line as a backup path?
