Description

The Honeywell K10145WH is an AC transformer used to power the L3000 LYNX Plus wireless alarm control panel. The K10145WH plug-in transformer is included with the L3000 LYNX Plus alarm control panel and is also included with the L3000PK LYNX Plus wireless security system kit.

The K10145WH is a 9VAC, 25VA plug-in transformer that does not include the wire needed to connect the transformer to the LYNX Plus control panel. You should use (2) conductor wire to connect the transformer. In the L3000 LYNX Plus installation guide, Honeywell recommends the following wire length limits when connecting the K10145WH to your LYNX Plus system. With wire gauge #20, you should not use a wire connection that is greater than 75’. With wire gauge #18, your wire connection should be between 75’ and 150’. Finally, with #16 wire gauge, your wire connection should be between 150’ and 300’. However, you can also use 22 gauge wire to connect your transformer. More often than not, the length of wire needed to connect your transformer to your control panel will be less than 75’ so 22 gauge is suitable.

To install your Honeywell K10145WH transformer, you should first measure out the length of wire needed. You will be measuring the distance between your chosen installation location of your L3000 LYNX Plus wireless alarm control panel and the wall outlet you will be using to plug in the AC transformer. Once you have measured the length of wire needed, you can choose the correct gauge of wire using the information above. Cut the length of wire, and strip off the outer insulating wire cover approximately 3” from each end of the wire. You will then have a red and black sheathed wire at each end. Strip off the red and black sheathing so that there is approximately 1” of exposed wire. You will have (2) exposed wires at each end of the wire. Open the LYNX Plus wireless alarm control panel and feed one end of the wire through the hole in the LYNX Plus back plate. Make sure the LYNXRCHKIT-SC battery backup is not connected, then connect one of the exposed wires to terminal 10 and the other exposed wire to terminal 11 on the terminal block of the LYNX Plus control panel. Both terminals will be labeled as “AC”, and polarity does not matter, so you can use either color (red or black) in either terminal. You will need a small Phillips head screwdriver to connect the wire to the terminal. Unscrew each terminal screw so that there is enough room to insert the exposed wire into the terminal block. There should be no exposed copper once the wire is fully inserted. If you do have exposed copper, simply trim down the wire. You will need to tighten the terminal screw to secure the connection. After connecting both the red and black wires to terminals 10 and 11, you will then need to connect the red and black wires at the other end of your wire to the screw terminals on the backside of the K10145WH transformer. Use your Phillips head screwdriver to unscrew the screws just enough to be able to fit the exposed copper wire around the screw head. Alarm Grid recommends bending the exposed copper wire over into a hook shape and then fitting the hook under the screw for the best connection. Once again, polarity does not matter so you can connect the red or black wire to either terminal screw. Ensure no exposed copper is showing once the hooked wire is underneath the screw head. Tighten down the (2) screw terminals to secure the connection. Finally, plug in the battery backup and close the LYNX Plus control panel. You can then plug the AC transformer into a standard 110VAC unswitched wall outlet. If the outlet is controlled by a light switch, someone may inadvertently cut power to your security system, so that is why you must ensure the outlet is unswitched. If you plug the transformer into a standard double outlet wall plate, you should use the bottom plug. Remove the screw from the middle of the outlet’s wall plate and replace it with the included screw that comes attached to the plastic flange at the top of the transformer to secure the K10145WH to the outlet. This ensures no one will accidentally remove the transformer from the outlet.

It is essential that you do not plug in the Honeywell K10145WH transformer before completing all wire connections. If you do plug the transformer in before connecting the wires, you run the risk of blowing out your transformer or, even worse, damaging your LYNX Plus wireless alarm control panel. Once your transformer has blown, there is no way to repair it and you will have to purchase a new K10145WH. As it is fairly easy to damage your AC transformer if you do not follow these steps, Alarm Grid does not offer refunds on damaged transformers. However, if you follow these steps, your transformer should work properly for the lifetime of your L3000 LYNX Plus alarm control panel.

Note: This transformer can also be used to power the wireless Interlogix Simon Series Alarm Panels, including the Simon XT, Simon XTi, Simon XTi-5, and Simon XTi-5i.

do the honeywell transfomer have anything to do with the voice stopped communicating? everything else works fine
I have two of these transformers in my home. one connected with wires ( I unscrewed it to from the outlet to observe this) and the other wasn't connected to any wires however was screwed in the outlet. I have lived in my house for 8 yrs and never had any issues but lately I've heard a noise coming from the transformer (without the wires). Then tonight I smelled burning, so I shut the electric and removed the transformer to find it burned out. The other one seems to be fine. Can anyone share what may have happened? It scared the crap out of me.
Here is a wired relay you can use for the external sounder: https://www.alarmgrid.com/products/altronix-rbsnttl. You can wire this directly to the trigger output of the L5100 you already have.
We offer the LYNX-EXT (https://www.alarmgrid.com/products/alarmgrid-lynx-ext) kit for hooking up wired sirens to an L5100. The LYNX-EXT uses an AC transformer so you'd have to be able to supply the proper input power for that transformer.
Thank you Frank for the information, I was looking at the models you mentioned above and it will be a lot easier using those panels with a reducer that will bring down 24vdc to 9vdc. I have a Lynx Touch 5100 that also uses DC power that I can use, but i will need a relay module with Trig inputs to power the outdoor siren. Again, thank you.
You will need to install a power inverter to get 110VAC. Then plug in this transformer to bring it down to 9VAC. If you install an inverter and plug in this transformer that is the only way Honeywell would support the installation. With that said, you may be looking for work arounds. You may find it easier to go with a LYNX Touch L5200 (https://www.alarmgrid.com/products/honeywell-l5200 ) or the L7000 (https://www.alarmgrid.com/products/honeywell-l7000 ) since it requires 9VDC instead VAC. Stepping down DC power can be less costly than inverting power. Here are the power specs on the included transformer (https://www.alarmgrid.com/products/honeywell-300-04705 ) for the LYNX Touch panels listed above: 9VDC, 2.5A. You would need a DC to DC Step Down (Buck) Converter like the LM2596. If you got this route you will want to involve an electrician before making any connections. If you have any further questions please reach out to Support@alarmgrid.com.
Has anybody connected a Lynx L3000 to a 24DC power? I have to install this panel on a boat but the guy only has 24vdc power.
