The 1045T Series features a wider make distance, which permits faster installation, accommodates greater misalignment and works better on steel without time-consuming brackets. A wider break distance helps prevent false alarms caused by loose fitting doors. Interlogix-specified contacts keep the 1045T Series from sticking or freezing on seldom-used doors. External test points simplify testing. Recessed terminals protect the contact from tampering or accidental electrical shorting.
