The telt 100 is a time relay for the automatic testing of emergency lighting systems, offering simple operation and flexible settings. The test can be initiated using a TEST button on the control panel, while the time delay can be precisely adjusted via a rotary switch in six steps (10 minutes to 180 minutes). The ZERO CROSS technology switches the output contact at zero voltage crossing, reducing wear and extending lifespan.
LEDs clearly indicate the operating status: a green LED signals the power supply, while a red LED indicates the output state, either blinking or steady. When power is supplied, contact “16” is closed, and pressing the TEST button closes contact “18” to test the emergency lights. After the set time delay, contact “18” reopens, and the lighting is reconnected via contact “16.” During the delay, the red LED blinks slowly.
Brief presses of the TEST button do not affect the delay, while a longer press (>2 seconds) ends it immediately. With its robust design and user-friendly technology, the telt 100 is a reliable solution for efficient testing of emergency lighting systems.
