The SKE-ZN4 is an evacuation zone splitter for use with the SKE-450. The SKE-ZN4 is capable of splitting the audio output from the main amp into four separate audio output zones orchannels.
The SKE-ZN4 can be used in installations where the audio must be split to different floors or zones to accommodate a safe and efficient evacuation process.

The RTS Series complies with the requirements of NFPA 13 and 72 for a room temperature switch to operate at 40°F to protect a dry pipe valve from freezing. The RTS can also be used for other temperature detection applications.

The normally open detector, RTS-O, will close the contact when the temperature drops below 40°F (4,5°C). The normally closed detector, RTS-C, will open the contact when the temperature drops below 40°F (4,5°C). The detector will automatically reset to the normal state when the temperature rises above 40°F (4,5°C). The RTS Series Room Temperature Sensors are precision engineered, designed and manufactured for commercial or residential use.

The i4 Interface Module connects up to 12 detectors to a wide range of control panels using only 2 to 3 zones. Carbon.
