System Sensor introduced its i⁴ Series Combination CO/Smoke Detector and Integration Module, which it says is the first low-voltage, system-connected combination smoke and carbon monoxide detector on the market. The i⁴ series features the ability to integrate into conventional security and fire panels and is available in two- and four-wire versions, each of which provide photoelectric smoke and electrochemical CO sensing technologies. The required i⁴ Integration Module sits next to the panel, easing installation by allowing the system to use 75 percent fewer wires, according to System Sensor. The i⁴ module is also compatible with System Sensor’s i³ Series smoke detectors with thermal sensors and built-in sounders, allowing the i⁴ to be used in both new installations and retrofits. Using any combination of i⁴ and compatible i³ Series detectors, users can integrate up to 12 devices on a loop.
