Has anybody any tips please for suitable combination locks for fire exit doors within a care home that cares for people with dementia and alzheimers? I am looking for a simple but effective mechanical combination lock with say just 5 buttons and no need to press Cs and Xs that can be used by staff or visitors in semi darkness etc. The old two opposing door handles has been rumbled and is no longer effective, and the home would prefer to avoid going down the electronic route if at all possible.
It is essential to provide some means of security as several residents are very active wandering through the home and are risk of falling down stairs, especially at night.
I am looking for something similar to the old discontinued Ilco 7006 range that is reliable and simple to operate but they all seem to be much more complicated now.
