The Honeywell 4209U V-Plex Group Zoning Remote Point Module allows a user to add additional 2-wire smoke detector loops to the commercial polling loop alarm panel. This useful module can support a maximum of 16 different 2-wire smoke detectors on each of its four individual loops.
As a group zoning module, the 4209U will uniquely identify either four supervised zones in the non-grouped mode, or two supervised zones if used in grouped mode. The module's DIP switches are used to set zone numbers or serial numbers. When used in DIP switch mode, the DIP setting determines the zone numbers used. This mode should only be used with panels that will not support a serial number. In serial number mode, the DIP settings determine which row of serial numbers will be used from the Installation Instructions, and each input can be programmed to any polling loop zone number available.
The module also offers tamper protection, and can alert the system if anyone tries to remove the cover. For best performance, the module should be mounted inside an alarm control panel cabinet or some other type of separate enclosure. This will ensure proper protection of the device and prevent damage.
All protection zones used with 4209U should have a 2k EOL resistor. These come included with the module. Even in grouped mode, each set of terminals will still require its own 2k EOLR. Each one must be connected in parallel across the terminals at the last smoke detector used on the zone.
Note: This device requires its own power input in addition to the connection to the panel's polling loop. You will also need some type of switch or relay to momentarily interrupt the module's input power after a smoke alarm activation. This is necessary for resetting the smoke detectors and clearing any alarms. This can be done using an auxiliary relay or a 4204 relay.
