NOTES
Approval of the Model PIRECL does not include or imply approval of the apparatus to which the detector may
be connected and which processes the electronic signal for eventual end use. In order to maintain an approved
system, the apparatus to which the detector is connected must also be approved.
This Approval does not include or imply Approval of the communications protocol or functions provided by the
software of this instrument or the communications apparatus or software connected to this instrument.
RESPONSE TIME (Average * in Seconds, with Weather Protection Baffle Installed, and 100% LFL Applied)—
* Average of three consecutive trials, with the minimum and maximum response times no greater
than ±2 seconds from the average indicated response time.
NOTE: Add 2 seconds to response time for EQP compatible models.
