UB-2 2” Universal Button
UB-2/LTUL Universal Button with Latching Timer
For UB-2/LTUL the enclosed timer is to be used and installed per the enclosed LT1UL installation sheet. For access control installations, power for the LT-1UL Timer
must be supplied by a power source listed to UL294. When used for access control,
this device shall be used as part of an access controlled egress door system. It is
up to the local AHJ to allow use of this device in place of an automatic sensor. For
higher security installations, lower time limits should be used.
We protect the things that protect you.
