Honeywell Home 6165EX Slimline Custom Alpha Display Keypad Compatible Systems & Integrations

Honeywell wired ECP keypad (6160, 6150, 6150RF, 6160RF, etc.) — alpha or fixed-display keypad on the panel data bus for arming, disarming, and zone status.

On Honeywell systems, wireless devices are supervised zones on the panel — tamper, low battery, and missing signals appear as trouble conditions that may block arming depending on panel programming.

Before You Service or Replace One

• Sensor SKU — 5800 Series one-way vs SiX two-way encrypted vs hardwired.
