The Dual Sense Bar (DSB) is for use on magnetically locked, non-fire-rated doors. Specifically designed to address the most current building and life safety codes, the DSB features two independent switch circuits to release the lock. Simply touching the bar or engaging its mechanical movement will allow free egress. For indoor use only, the DSB can be installed on metal, aluminum or wood doors of all types. Meets "no special tools or knowledge" requirements. Less than 1/8" mechanical movement and ultra-reliable touch sense technology working together in a single exit bar. Touch sensing and redundant movement-activated switches complies with current fire and life safety egress codes. Circuit board is immune to electrostatic discharge up to 27,000 volts from items such as switching power supplies, proximity and garment readers and neon signs. Bounce resistant to false triggering from outside impact. All metal construction will stand up to rugged interior environments. The DSB allows field cutting to fit non-standard door widths.
