The Honeywell Home 4209U Group Zoning Multiplex Module is a 4-zone expander that streamlines large or expanded Honeywell ADEMCO controls that support polling loop devices. Its primary purpose is to provide additional 2-wire smoke detector loops to the control.
In retrofit applications, installers can utilize existing hardwired smoke detectors (UL Compatibility Listed) and wiring to expand system-wide smoke detector capability and capacity. The 4209U also offers flexible zone configurations to meet the varying demands of commercial applications. The 4209U is recommended for commercial systems (e.g. VISTA 50P, VISTA 128BPT and VISTA 250BPT) when deploying conventional detectors in an ECP zone expandable system.
Product Features:
Uniquely identifies 4 supervised zones or 2 supervised zones in the "grouped" mode (groups two supervised zones together into one zone).
Supports up to 16 2-wire smoke detectors on each of its 4 loops, regardless of group setting.
DIP Switches can be used to set zone numbers or serial numbers
When used in the serial number mode, each serial number in the selected group can be assigned to any zone number.
When the module is to be mounted inside the control's cabinet tamper protection is not required if the cabinet is supervised. Insert self-tapping screws (provided) in two adjacent raised tabs at the back of the cabinet, leaving the heads projecting 1/8". Hang the module on the screw heads via the two slotted holes on the back of the module's housing. When the installation is complete install the cover and affix the Serial Number and Zone Assignment Tables to the inside cover of the control.

Polling loop and protection loop wires can be brought in either through the back or front of the unit by removing the knockouts. Use 22 gauge twisted pair wire for polling loop connections. All protection loops use 2k EOL resistors (included). A maximum resistance of 100 ohms is allowed on protection loops (excluding EOLR). Keep in mind that even in the grouped mode, each set of terminals must have its own 2k EOLR, and it must be connected across the loop wires at the last detector.
Power Connections must be made so that power to the smoke detectors can be momentarily interrupted to clear the alarm. This can be done either via the control's auxiliary relay (if supported) or through a relay on a 4204 relay module. Wire the common of the relay to 12VDC and the N.C. contact on the 4209U (TB2, terminal 3). The relay you use must be programmed for "Smoke Protector Reset". When you reset an alarm at the keypad, the relay arm will swing momentarily to the N.O. contact, causing an interruption of power.
In the zone assignment mode, the DIP Switches on the 4209U are used to assign the unit to a group of 4 consecutive zones in the "non-grouped" mode, or 2 consecutive zones in the "grouped" mode. These zone numbers, once designated for the 4209U, cannot be used for anything else, even if you don't use them all.
In the serial number mode, the DIP Switches on the 4209U are used to assign the unit to a group of 4 serial numbers, or 2 serial numbers in the "grouped" mode. You can assign any serial number to any zone number (except hardwire zone numbers on the control) and you do not lose zone numbers if you don't use all 4 loops on the 4209U.
