TD-135

Is a two-zone fire alarm control panel that uniquely combines both two-wire and conventional wiring technologies. This means each zone can be individually configured to operate as either a two-wire or a conventional system, allowing for a flexible mix of both types of devices on the same panel. It features an intuitive interface for straightforward programming and maintenance and meets the EN54 parts 2 and 4 standards.

Is a 2-wire conventional fire detector that combines both rate-of-rise and fixed heat detection. It is designed to respond to a rapid increase in temperature and/or temperatures exceeding a threshold of \(135^{\circ }F\) (\(60^{\circ }C\)), making it suitable for environments where smoke detectors may cause false alarms, such as those with high levels of dust or steam.

S a two-wire, conventional photo-thermal fire detector from Eaton's UL-listed conventional detector range. It combines a photo-thermal detector with a thermal enhancement for faster detection of clean-burning fires while also detecting slower smoldering fires. It has a thermal alarm threshold of \(60^{\circ }C\) and is designed for environments where standard smoke detectors might trigger false alarms.

Is a compact, UL-listed single-channel output unit for Eaton's addressable fire alarm systems, which is identified by the panel as a sounder. It is used to control low-voltage devices by switching them, such as for fire door closures or plant shutdown circuits. The "S" designation signifies its primary use as a sounder, and it features easy, "plug and play" installation with no hard addressing required.
