Wired Garage Door Alarm Sensors Frequently Asked Questions
Can an Alarm Sensor be Attached to a Garage Door?
Many alarm systems use garage door sensors to determine when the garage door is left open. These can be very useful sensors for security systems. Learn about garage door sensors.
Can a Key Fob Button be Used as a Trigger to Automate a Garage Door?
A key fob input can be used to activate a scene that operates a garage door. A smart garage opener or relay and a tilt sensor are both needed. Learn how to control a garage door.
What Is a Security Door Contact?
When attached to a door, a security contact will let the system know when the door has been opened. Both wireless and wired door contacts are available.
What is Zone-Doubling on a Honeywell VISTA System?
Zone-doubling is a method of using different value resistors on zones 2 - 8 to allow 7 hardwired zone inputs to behave like 14 separate zones. This is particularly helpful if you need more than 8 hardwired zones, but fewer than 16. Zone 2, doubled, becomes 2 and 10, zone 3 becomes 3 and 11, and so on.
Why Isn't My Wired Door Sensor Working?
A wired door sensor may not be showing the correct status due to programming or wiring issues. Read on to find out how to troubleshoot wired door sensors.
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.
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.
