The Honeywell 300-04705 is a power supply used to supply primary power to the Honeywell LYNX Touch systems (L5000, L5100, L5200, L5210 or L7000) and the new and improved Lyric system. The 300-04705 is a (2) prong plug-in power supply that converts 110VAC power coming out of your standard American wall outlets to a usable level for the LYNX Touch and Lyric security systems. This power supply can only accept power inputs between 102-132VAC. If you are using this product internationally be sure to use a separately purchased adapter so that this power supply is plugged into a power source that offers AC voltage within that range.
The 300-04705 plug-in power supply is included with each new L5200 or L7000 LYNX Touch wireless alarm control panel so that you don't need to purchase a transformer separately. The power supply has a 9VDC, 2.5A output which supplies the needed voltage to power the LYNX Touch alarm control panels. Unlike the K1914WH AC transformer that powers the L3000 LYNX Plus wireless alarm control panel, you must observe polarity when connecting the 300-04705 to your alarm control panel. The screw terminals on the backside of the 300-04705 power supply are labeled ‘+’ and ‘-’ to ensure you don’t accidentally cross the wires and damage the power supply.
To connect the Honeywell 300-04705 power supply to your LYNX Touch wireless alarm control panel you will need either the LT-CABLE or a length of (2) conductor alarm wire. If you choose to use the LT-CABLE, it will be much easier to connect the power supply to the control panel. The LT-CABLE has a DC plug on one end and (2) spade connectors (one red and one black) on the other end so wire stripping is not required.
If you do not use the LT-CABLE, you will need to make the connection between the wireless alarm control panel and the Honeywell 300-04705 power supply using (2) conductor 18/20/22 gauge alarm wire. If you use #22 gauge wire, the distance between the power supply and the control panel must not exceed 11’. If you use #20 gauge wire, you can use a maximum distance of 20’ between the power supply and the alarm panel. Finally, with #18 gauge wire, you can extend the connection up to a maximum of 26’. You will need to strip both ends of the wire after cutting the appropriate length. You will connect the red wire at one end to the ‘+9VDC’ terminal on the alarm system's circuit board. The black wire at the same end will connect to the ‘GND’ terminal at the panel. The red and black wires at the other end will be landed under the screw terminals on the backside of the 300-04705 power supply. Make sure to land the red wire lead underneath the screw labeled (+) and the black wire under the screw labeled (-); otherwise you run the risk of blowing out your power supply. Also, make sure there is no exposed copper wire showing on either end of the connection. All exposed wire should be completely inside the terminal block of the screw terminals and completely under the screw heads of the 300-04705. Once the power supply is blown, you will not be able to fix it and you will have to purchase a new 300-04705. Alarm Grid does not offer refunds on power supplies so be very careful when making your connections.
Even though the battery backup will continue to power the alarm control panel (for up to (4) hours with standard capacity battery) after AC power is removed, you do not want your power supply to become unplugged by someone that may not know it is powering your security system. Therefore, we recommend using the included screw that is attached to the plastic flange at the top of the power supply. You will need to first unscrew the screw that holds your plastic outlet cover in place. Next, you will need to plug the 300-04705 power supply into the bottom plug. Finally, use the power supply’s screw to secure the 300-04705 to the wall plate. The screw will keep the power supply from accidentally becoming unplugged and will secure the outlet cover to the wall outlet. The screw only interfaces with a standard duplex outlet. If you have a decora style outlet you may want to consider swapping your outlet out. Make sure to kill the circuit breaker before working with your home's electrical!
