How Do I Install A Honeywell 5800C2W?

If possible, mount the Honeywell 5800C2W next to the existing hardwired control panel metal house (box) using double sided tape and or screws. Do not install inside the metal box as this will cause RF interference. The metal box can be used to store the battery for the 5800C2W. From the hardwired control panel, remove and tag the hardwired sensor wires. The 5800C2W can convert up to 9 hardwired zones. Mount the tamper magnet to the enclosure cover. Use cable ties to secure wiring. Connect the red wire to one of the terminals on the transformer then to the positive (+) terminal number 1 on the 5800C2W. Now connect the black wire to the other terminal on the transformer to the (-) negative terminal number 2 on the 5800C2W. Plug the transformer in to an outlet that is not controlled by a wall switch. Now attach the battery backup wires, the black wire connecting to the (-) negative and the red wire connecting to the (+) positive on the 5800C2W. Make sure to position the integral battery cable fuse inside the control panel.

Click the SW2 button on the top left of the 5800C2W. This will start the calibration of the modules. The calibration enables the 5800C2W to learn what zones will be active and what value EOL resistors are used. Any unused zones will not be recognized or reported. Once the SW2 is clicked the indicator LED #1 will flash red for ½ second, then will turn to a steady green. Once the LED turns green the calibration is completed and the 5800C2W can be enrolled into the control panel.

The 5800C2W has a unique 7 digit serial number which enables the control panel to recognize it. The 5800C2W has 9 zones so each zone will automatically be assigned the next sequential serial number. All zones should be programmed to loop 1. Please refer to the control panel’s wireless zone programming for complete instructions.

Awesome. Once monitored, we do provide free technical support. We hope to hear from you soon.
Hi Ciara, thanks for the reply. The manual is unfortunatly of no help. I am also in the process of upgrading my alarm system to also start a monitoring plan with you guys.
Hi Red, Blinking red means the module needs calibrating and possibly the DC power is not being detected. Please make sure to check the wiring. Refer to the installation manual If you are a monitored customer, please email us at or give us a call at 888-818-7728 and we will be happy to troubleshoot with you. If not, we do offer affordable monitoring plans here at
Hi, I am trying to install a 5800c2w to my old wired alarm system. When I hit the sw2 the led starts blinking red and does not stop. Any idea what this could mean please ?
Thanks, Sterling.
If you wire the two sensors in series, then you can hook up both sensors to one zone. You would lose the ability to differentiate between the two window sensors when they activate. If you wanted the sensors to activate separate zones, you would have to wire them each to a separate zone on the 5800C2W.
Can I land two window sensors on the terminals for one zone. Would this require different resistor values for each window lead?
