Does the OSI Alarm support wired zones? If so does it include the connector & How do you use it?

Do I need to use those wires and resistors?

Those resistors and colored wires (which is called "Wired Zone Connector") are used for advanced users/alarm technicians who wish to connect the OSI Alarm System to their pre-existing Wired Sensors which were previously used in their old alarm system. The pre-exisiting wired sensors connect to the Wired Zone Connector which come included in the kit. A very small percentage actually use these, but some people who may have put an investment of money in their last alarm system and may still want to actually use the installed wired sensors. 

So what you should do with those resistors and connector if you are not connecting the alarm to pre-existing wired alarm sensors? You can discard them! Otherwise if you are, then please read on.

Important: Wired zones for the panel only support 'NO' (normally open) sensors

How to connect your Wired Sensors using the Wired Defense Zone Connector & Resistors?

The Host Supports up to 4 Wired Defense Zones, name and type which can be set separately. On page 10 of the 8 Piece OSI Alarm manual it shows you how to add the wired zones to the display (host)

There are 6 wires : 4x color wire (corresponding to Z1, Z2, Z3, Z4), and 2x black wire (corresponding to GND). See image below    

To connect a wired detector Simply connect 1x color wire (followed by 1 EOLR resistor wire in NC Connection wiring mode) to Normally Close Port on your existing wired detector, and 1x black wire to Common Port on your existing wired detector. 

Most wired detectors on the market have such ports for connection. as shown below:  

What are the Resistors for?

While most of wired detectors come with NC Connection wiring mode, some might come with NO Connection wiring mode. In that case, just use the EOLR resistor wire to connect both the color wire and black wire. 

NC means normally-closed contact. NO means normally-open contact. When the relay coil is de-energized, NC contact becomes open, and NO contact closes. 

EOLR - End of line resistors are resistors of a specified value that are used to terminate protective loops or zones. 

Below is an example where we connect 1 wired zone to a Paradox wired motion detector (other detectors like smoke detectors should also work).
