Our 12-24 VAC/VDC digital timer is a reliable and highly accurate simple solution to complex timing applications. A momentary contact closure begins the timing cycle (15, 30, 45 seconds or indefinitely) and latches a set of Form "C" dry contacts. The compact design makes it versatile for many applications.
The LT-1UL timer is compatible with all UL Listed momentary Stopper Station buttons and can be used with any UL Listed access momentary button.
For example, when used on an egress door, the supervised contacts can be set to either 'Fail Safe' or 'Fail Secure' mode. A built-in reset feature allows the circuit to reset after a single operation or a single door open and close (single passage) before timing expires. This prevents re-entry of any unauthorized personnel.
