Honeywell Ademco 6164US Custom Alpha Keypad w/ Four Zones

The Honeywell ADEMCO 6164US is a 12 VDC custom alphanumeric security keypad with four integrated hardwired zones and one Form C relay for compatible Honeywell VISTA intrusion alarm control panels. It features a 32-character backlit LCD, four programmable function keys, illuminated numeric keys, and audible system status alerts. The built-in zone expander supports conventional 2 k end-of-line resistor supervision or double-balanced zone wiring, reducing the need for a separate expansion module. Its white housing includes a removable keypad cover and integrated tamper detection.

Honeywell ADEMCO 6164US Custom Alpha Security Keypad with 4 Hardwired Zones and Relay

The Honeywell ADEMCO 6164US Custom Alpha Keypad provides intrusion alarm system control, status monitoring, and integrated hardwired zone expansion for compatible Honeywell VISTA security panels. Manufactured by Resideo under the Honeywell Home brand, this white keypad combines a two-line, 32-character alphanumeric LCD, four hardwired protection zones, and one Form C relay in a single wall-mounted device. Users can arm and disarm the connected alarm system, review zone conditions, and receive plain-English status messages through the backlit display. Its integrated zone inputs allow installers to connect nearby door contacts, motion detectors, and other compatible sensors directly to the keypad, reducing field wiring back to the main control panel. The 6164US is suitable for residential and commercial intrusion security installations requiring expanded zone capacity near an entryway or other keypad location.

The 6164US incorporates four supervised hardwired zones with a 300-millisecond response time and support for conventional 2 k end-of-line resistor (EOLR) wiring or double-balanced supervision. In double-balanced mode, each zone supports up to 10 compatible sensors, subject to the connected control panel's programming and supervision requirements. The keypad also includes one Form C relay rated at 1 A at 24 VAC/DC, providing normally open, normally closed, and common connections for compatible auxiliary control functions, including lighting or garage door interfaces. Zone and relay expansion requires a VISTA control panel that supports the Honeywell 4229 ECP expansion module, with the keypad's integrated expander enabled and assigned an appropriate address. The internal relay is not intended for UL installations, and the keypad's integrated zones must not be used for commercial fire alarm applications.

For everyday security operation, the Honeywell 6164US features 16 illuminated telephone-style keys and four programmable A, B, C, and D function buttons. The function buttons can initiate supported emergency commands, including burglary, fire, or personal emergency functions, or provide single-button arming when configured through the alarm panel. A built-in speaker delivers audible feedback for entry and exit delays, alarm conditions, system trouble events, and keypad command confirmation. Dedicated ARMED and READY LED indicators display the system's current status, while configurable display and sound settings allow the keypad to accommodate different installation preferences. The integrated tamper switch detects removal of the keypad cover or mounting assembly when supported and properly configured. The decorative removable door conceals the numeric keypad while leaving the primary function buttons accessible for convenient operation.

The 6164US operates from a nominal 12 VDC auxiliary power connection and communicates with the alarm control panel through the standard four-wire Honeywell ECP keypad bus. Manufacturer specifications identify 55 mA standby current with the display backlight, sounder, and relay off, and 190 mA activated current with the backlight and sounder operating. The keypad measures 5-3/8 inches high, 7-3/8 inches wide, and 1-1/4 inches deep (137 187 32 mm) and supports direct wall mounting or installation over compatible single-gang and double-gang electrical boxes. Local programming allows installers to configure the keypad address, expander address, zone supervision method, tamper operation, display behavior, and audible feedback. The 6164US is compatible with VISTA control panels supporting the 6160 keypad, while its four-zone expansion and relay functions require additional 4229-compatible panel support. Installation should follow the manufacturer's wiring instructions, control panel programming requirements, and applicable intrusion alarm standards.
