Hi there. This is my first post so I'll try not to embarrass myself.
I need to disarm a partition on an "Ademco" Vista 128 alarm panel from my "Keyscan" ACU4300 access control panel. I'm using the keyswitch input (zone77) on the Ademco, and it needs a 2 second dry contact closure but all I have from my Keyscan is a latched dry contact. So does anybody know what I need to do? Do I have to make a circuit with a 555 timer and a relay or are there products out there to do this? Any advice would be appreciated.
thanks
