Re: Necessary Change Order
It has come to my attention that the below listed doors are not functioning properly and after consultation with Vikonics, Samuels Electric Company personnel, and Glen Pymento of DCAS, a recommendation has been made to correct the deficiency. The problem arises from the push to exit button not properly releasing the doors. It appears that the action of these buttons is causing the security panel to freeze up, thereby not releasing the magnetic locking device.
The solution to this problem has been devised by Samuels Electric and Vlkonics, with the scope of work necessary to correct it attached.
The doors needing the repairs are :
23-30, 23-33, 23-49, 23-50, 23-25, 23-28
For your information and attention.
