V-Plex (polling loop) devices. polling loop exceeds the recommended length (1220 m). $15.00. V-Plex sensors operate on low current, greatly simplifying system design. Fundamentally, V-Plex bus is a 2-wire cable that is installed around a facility. VPLEX-VSI and the polling loop devices located farthest for the VPLEX-VSI, should be kept within the following wired limits. By installing the 4297 at the end of the first loop, you can expand the polling loop. Bus solutions have always had great advantages and V-Plex is no exception. Designed to work on all Honeywell V-Plex polling loops, the VPLEX-VSI provides short circuit isolation for devices on compatible control panels. A Vplex polling loop device is disclosed which can automatically detect and isolate shorted or overloaded sections of a polling loop, before or after polling loop power and signaling is switched to the output of the device, permitting normal operation of the remaining portion of the polling loop. VISTAKEY® is an ideal way to incorporate just the right combination of security and Free shipping . (polling loop) devices. This device is designed for use only with controls supporting V-Plex (polling loop) technology. New 736V V-Plex Module Makes it Easy to Upgrade V-Plex Systems . The DMP interface module that lets you take over a Honeywell V-Plex System is now shipping. sealed insulating glass. Turn a Honeywell® V-Plex® Polling Loop into a DMP LX-Bus™ July 09, 2019. Features Can also be used as a short circuit isolator. Image not available. Picture Information. NOTE: The VPLEX-VSI does not add to the maximum length of any branch or the maximum sum length of all branches as listed in your control panel manual. A Vplex polling loop device is disclosed which can automatically detect and isolate shorted or overloaded sections of a polling loop, before or after polling loop power and signaling is switched to the output of the device, permitting normal operation of the remaining portion of the polling loop. power supply to reduce the amount of current draw from the polling loop. Control units for use in Canada utilizing polling loops require compatibility analysis by Underwriters' Laboratories of Canada for glass break detectors that are intended to be connected to these control units. V-Plex patented global polling loop technology provides ... the 4293SN makes any hardwired contact device V-Plex ready! Opens image gallery. If more than 64 mA needs to be drawn from the polling loop to power RPMs, the 4297 extender module provides another loop with 128 mA available. $15.00 + shipping . ONE BRAND NEW Honeywell 4297 V-Plex Polling Loop Extender Module . SAVE UP TO 5% See all eligible items. Designed to work on all Honeywell V-Plex polling loops, the VPLEX-VSI provides short circuit isolation for devices on compatible control panels. The 4297 module receives signals from the control panel via its "input" loop, and then re-transmits boosted copies of these signals via its "extension" loop. NOTE: The 4208U cannot be used with an external power supply for commercial fire applications. ONE of the neat new things I saw at Security 2014 was Honeywell’s V-Plex bus, a patented polling loop in the form of a 2-wire cable system that works with Vista 120, 250 and Tuxedo 12/48. Honeywell 4297 V-Plex Polling Loop Extender Module. Characteristics of this device include: • Can be optionally powered from the control panel aux.
