Resistive edges have two semi-conductive strips inside. They connect when pressure is applied. They come in all sizes. Larger profiles respond better to side pressure.
The end of the edge is terminated with an 8k2 resistor. A processor is needed to convert the edge resistance to an N/C relay contact for a control panel.
Some panel inputs already have a 8k2 option. The DRI is a processor small enough to fit inside most edges.
DRE edges are available in 30mm high and 50mm high profiles.
installer packs have enough parts to make 12 edges of 2m long.
Several edges can be interconnected using a special plug-in cable. DRE edges can be trimmed to suit on site.
Concealed mounting is neat feature, especially when fitted to a black steel post
8k2 processors
Resistive edge need processors to convert resistance to a N/C contact.
DRI - is a single channel processor small enough to fit inside most edges.
VDC82 - is a dual channel processor for mounting in a control panel. Each channel can take 2 edges. There are programming options for the outputs such as toggling or hold open.
Resistive edge need processors to convert resistance to a N/C contact.
VDC73 - is a safety router. It combines 3 resistive processors, an access control PSU and interface, activation button, and a bank of DIP switches for quick configuration. Work smart with Diablo Controls safety routers.
Safety routers - combine all wiring on a gate post down to just one cable. That includes photobeams & safety edges, photobeams, intercoms, safety edges, intercoms and keypad. And to make it easy, functions and interconnections are set by DIP switches.
Safety router application. E1, E2 and beam 2 are on 'pause' channel, E3 and beam2 are on 're-open' channel.
DTE edges
Taught wire safety edges are large rubber edges suitable for fast closing gaps. They have good mechanical protection and trigger from pressure in three directions.
A wire runs the full length under tension. When it is pressed, it triggers a micro-switch inside. A second micro-switch detects wire failure, so DTE edges are Cat1.
DCY Strip hinge edges
DCY strip hinge edges are low profile and discrete, so popular with clients. Strip hinge edges, are formed between two aluminium strips and two microswitches. DCY edges have a short activation distance and small overtravel, so are only used on slower closing gaps.
Two microswitches give the redundancy required for Cat1. They only activate in one direction. Any number of edge contacts can be wired in series, but would not be Cat2 tested.
A common application is to protect finger traps near a gate hinge. They are low profile and discrete (especially the black version) so popular with clients.
DCY has 5mm rubber tip slid into a slot in the top extrusion. It can be replaced by larger rubber tip increasing the width by 6.5mm.
Unique corner connectors make these edges all round protection for garage doors.
