Hello, electronics are still fresh waters for me so apologies in advance.
Im looking for a certain kind of time relay or something similar that has COM and NC dry contact that will not change state unless something is pressed down for a set amount of time (lets say 30 seconds), If it is released before set time it will not open/release contact.
For reference : (DE = Delay Egress)
Working on a crash bar that has COM,NC,NO contacts. crash bar needs to activate delay egress on a mag lock if it is held for 30 seconds. The issue I have is the maglock will activate DE when contacts it has are opened , It has a nuisance delay option but it only goes up to 3 seconds. The reason it has to be 30 seconds is because the door is capable of engaging the crash bar and opening when someone unlocks it using a code tied to a small makeshift access control box. There are no more points left on it so we are having to make shift some more. The crash bar being held during the unlock time can have no affect on DE point on maglock. The crashbar must be engaged when for longer that 30 seconds to activate DE timer.
hope this makes sense, will add drawing of what im thinking since my english is horrendous.
The relay currently on the drawing (with yellow trigger) was what i thought i originally needed until i realized data sheet said it would start release timer as soon as it was triggered.
