Wired Smoke Detectors Frequently Asked Questions
What's the wire length limit on a Honeywell VISTA's polling loop?
There are strict limits on polling loop distance, based on current drawn, and wire gauge used. Learn the rules and limits for wiring the polling loop.

How Do I Connect a 4193SN to a VISTA-128BPT, 250BPT or VISTA-50?
The 4193SN connects to the Vista-128BPT, 250BPT, or 50 through the polling loop on terminals 24 (Positive) and 25 (Negative). Learn how to wire the 4193SN.
How Do I Add a 4193SN to My VISTA-128BPT, 250BPT or VISTA-50?
The 4193SN is an expansion device which allows users to add conventional devices to the polling loop by programming its serial number into the zone(s). Read on.
How Do I Program a 4193SN to a VISTA-128BPT, 250BPT, or VISTA-50?
The Vista-128BPT and similar panels use a polling loop for wired expansion. In zone programming, use input type to identify zones. Learn to program a 4193SN.
Can an End of Line Relay Cause Power Failure on a Zone?
End of Line relays are used on 4-wire smoke zones to alert the end-user if the smokes experience power loss, but wouldn’t cause a power failure. Read on!
Should I Use Resistors on my VISTA 21iP?
When using hardwired zones, it is more secure and tamper proof to use End of Line Resistors to supervise zone wiring. Find out the pros and cons here.
Lyric Gateway Vs. Honeywell Vista System
This comparison chart highlights common features between the two panel types. Decide which panel is right for you.
How do I clear a trouble caused by a Firefighter FF345?
To clear a trouble, determine the cause, resolve the issue, then disarm your system. A trouble can be caused by a tamper condition, or a failure to properly reset. Keep reading to learn more.
