Path Length Searchline Excel Plus: 2 m to 120 m (6 ft to 393 ft)
Searchline Excel Edge: 60 m to 330 m (196 ft to 1082 ft)
Speed of Response T90 less than 3 seconds
Analog Output Signal 420 mA Normal operation, 1 mA Fault*
2 mA Inhibit, 3 mA Warning, 21 mA Overrange
*Searchline Excel Plus and Searchline Excel Edge will indicate Fault after 30 s without signal.
This value is programmable. To comply with FM performance approval, the maximum value for
Time to Block is 200 s.

* Searchline Excel Plus & Edge will respond to most hydrocarbon gases as most do absorb IR in the required wavelengths.
** Calibration to Universal Hydrocarbon covers a range of specific but different gases within one calibration that meets
the requirements of the performance standard.
