What causes the electric strike locks on or gate operator to hold open on DoorKing 1812 Classic Intercom System?
This can be due to excessive voltage drop on the 24 VAC line. Another potential cause is the relay auto-activate time zone being enabled; turn it off or reprogram the time zone. Also, the entry code used might have been programmed under a hold location code; reprogram the entry code into a momentary activation location code.
Why won't my DoorKing 1812 Classic answer when called from the residents phone?
You might be using the wrong attention number. Try re-programming the attention number.
