Adding a Siren to A Honeywell VISTA Alarm System

In this video, Joe from Alarm Grid shows you how to add a wired siren to a VISTA Panel. The easiest way to do this is to connect the siren to Terminals 4 and 4 on the panel board. The siren will draw power from the panel's backup battery when activated. Multiple sirens can be daisy-chained together.

A siren is an important addition for a VISTA Security System. These hardwired panels do not have their own internal sounders. Although a keypad will provide some sound during an alarm event, it is not as much as a siren. Fortunately, it isn't as difficult as you might think to add a wired siren. As long as you do not exceed 2A of power, then you can simply wire a siren to Terminals 3 and 4 on the system board. If you want to use multiple sirens, then you can daisy-chain them together. This works fine as long as you do not exceed 2A. Remember that sirens can only be used in this manner if the system has a charged backup battery.

Sirens are critical for making sure that building occupants are alerted during burglary and fire alarms. For most homes and small businesses, a super powerful siren is not needed. In fact, a siren in the range of 90 dB to 100 dB will usually suffice. However, industrial grade sirens are also available for those who need something louder. This is often the case for large businesses, warehouses, manufacturing facilities, schools, large churches, and more. It's fair to expect that a siren used at one of those facilities would be capable of producing sounds of up to 125 dB, though that would be on the extreme end. For a VISTA System, an auxiliary power supply and relay will be needed to use any siren setup that exceeds 2A.
