The System Sensor Indoor L-Series Selectable Output Low Frequency Sounder Strobe is an advanced alarm signaling device that meets top - notch safety standards. Certified under UL 1971 and UL 464 for public mode evacuation, it's perfect for various indoor spaces like commercial buildings, schools, and healthcare centers. The innovative low - frequency sound output makes it highly effective in alerting people with hearing impairments, ensuring everyone's safety. The L - Series offers a full range of candela strobe settings. High candela settings are great for ADA - compliant sleeping areas, while lower settings help optimize current draw in places like nursing homes. You can also choose the candela settings on - site according to your specific needs, enhancing both safety and efficiency. With its modern look, it fits seamlessly into any fire alarm system. Installation is a breeze thanks to the plug - in design that barely intrudes into the back box. The mounting plate has a shorting spring to check wiring continuity before installation, guaranteeing a reliable setup. It's electrically compatible with old SpectrAlert and SpectrAlert Advance devices, so it can directly replace older models. Whether you mount it on the wall or ceiling, the L - Series is easy to use and performs well in any situation.

Using the System Sensor Indoor L - Series Selectable Output Low Frequency Sounder Strobe is quite straightforward. First, decide whether you want to mount it on the wall or ceiling. Then, use the plug - in design to install it, but make sure to use the shorting spring on the mounting plate to check the wiring continuity before fully setting it up. You can choose different candela settings according to where you're installing it. For example, use high candela settings in sleeping areas that need to meet ADA standards, and lower settings in places like nursing homes to save power. The rotary switch allows you to set different modes like High/Low, Temp3, Temp4, and Continuous. Sounder - only models also have a Coded setting. When it comes to maintenance, keep an eye on the operating temperature and humidity. The device works best between 32°F to 120°F (0°C to 49°C) and in a humidity range of 10 to 93% non - condensing. Check the wiring regularly to ensure there are no loose connections. If you need to sync it with other devices, make sure the MDL3 sync module's operating voltage is within the 16.5 to 33 V (24 V nominal) range. Also, use the right wire gauge (12 to 18 AWG) for the input terminals. With proper use and maintenance, this device will keep you and your place safe for a long time.
