One of the most popular Ademco alarm systems is the Honeywell Ademco VISTA-20P, according to user reviews on Amazon and JMAC Supply Systems Guru Adolfo Zarate. The alarm system has an average user rating of 4.6 stars out of five on Amazon, as of 2016.Continue Reading
The Honeywell Ademco VISTA-20P can support up to 48 zones when expanded through hardwired and wireless modules. It supports four different touchscreen keypads, giving the user plenty of keypad options. Adolfo Zarate, the Systems Guru at JMAC Supply, states the system is user-friendly, making it simple for the average home owner to determine how to hardwire the system himself. This is because the system comes with a well-developed user manual that explains the process in detail.
A 12-volt, 7-amp battery, which must be purchased separately, generates enough battery power to keep the system live for up to 24 hours should a power failure cut power to its hardwired electrical system. Zarate notes the system isn't capable of providing self-monitoring features, which means the home owner or an emergency contact cannot be contacted in the event of a security breach. Zarate also notes the system's outdated nature, giving it a non-aesthetically pleasing look that makes it hard to compete with updated models. The drawback of only being able to reach 48 zones by purchasing expansion modules is also a con, according to Zarate.Learn more about Doors, Windows, & Locks
