September 21, 2007 - Centered around the WireFree OI-WF690 and OI-WF190 Sensor Assemblies that detect either toxic or LEL gases and feature non-intrusive calibration, the WireFree system consists of Interface OIWF95, Relayer OI-WF752, View OI-WF910, and the ProSafe OI-WF784. Each uniquely compatible with multiple WireFree Sensor Assemblies, these four devices serve as a receiver, relay assembly, signal strength meter, and monitor (respectively) that create flexibility through customizable variety. The Interface OI-WF985, The Relayer OI-WF752, The View OI-WF910, and the ProSafe OI-WF784 can be mounted virtually anywhere. Time is money—WireFree saves both While being a durable product needing fewer replacements from water damage or lighting strikes is definitely a perk, there's yet another advantage to WireFree that hits close to home - it's economical. With the ability to be mounted in various locations, technicians spend no time repeatedly traveling from site to site checking the status of sensors—because they can do so from the office, a site's entrance, or wherever else they choose! The WireFree system is communicably united by the 7-mile line-of-site 900MHz radio contained by each device. The Interface OI-WF985 is a 32 channel receiver that works collectively with a PLC, PC or other monitor, while The Relayer OI-WF752 uses Red and Amber LEDs coupled with Low and High 10-Amp alarm relays to notify the user of unsafe gas levels from up to eight sensor assemblies. The View OI-WF910 is a hand-held device that enables the user to measure the signal strength of an infinite number of WireFree Sensor Assemblies, and the ProSafe OI-WF784 is capable of monitoring up to eight WireFree Sensor Assemblies and triggering four alarm relays: Low, High, AUX Low and AUX High.
