Honeywell Home Lyric Controller LCP500-L

The Lyric Controller (LCP500-L in the US, LCP500-LC in Canada) is Honeywell's touchscreen all-in-one panel that followed the Lynx Touch. It adds built-in Wi-Fi and support for Honeywell's encrypted, two-way SiX wireless sensors, while still working with older 5800-series sensors.

At a glance

Resideo's newer ProSeries panels have since replaced the Lyric for new installs, but Lyric systems remain common and fully serviceable.

Troubles appear on screen with the device involved. For AC loss, low battery, supervision, and communication alerts, see Lynx and Lyric troubles. A Lyric-specific one: Wi-Fi disconnected after a router change. Reconnect from the panel's Wi-Fi settings.

No cellular backup

Without a LYRICLTE-A / LYRICLTE-V (or LYRICLTE-C in Canada), the Lyric depends entirely on Wi-Fi. A power or internet outage then cuts off monitoring. Adding the LTE module is the most valuable upgrade for most Lyric owners.

Battery goes low quickly

The standard pack gives a few hours of standby. If outages are common where you live, fit the 24-hour pack. A pack that drops to low within minutes of losing AC needs replacing.

A SiX sensor will not enroll

SiX devices enroll differently from 5800 sensors: the panel and sensor exchange encryption keys. Bring the sensor close to the panel for enrollment, then mount it.

• Keypads: LKP500-EN, LKP500-ENC (Canada).
• Cellular: LYRICLTE-A, LYRICLTE-V, LYRICLTE-C.
• Batteries: LCP500-4B, LCP500-24B.
• Sensors: SiX series and 5800-series.

• Mount on its wall plate or the LCP500-DK desk stand, near the middle of the home.
• Connect Wi-Fi during setup and confirm the monitoring company receives signals before relying on it.
• LKP500 keypads are wireless SiX devices; they enroll like sensors.
• Programming uses the installer code (default 4112). See installer vs master codes.
