< System Sensitivity:
Sensitivity for the standard controller is field adjustable over a range of 8 through
120 counts per second (cps) in increments of 8 cps. The maximum response
distance is achieved at an 8 cps sensitivity setting. For applications involving high
background radiation potential, the system can be de-sensitized by increasing the
count rate required to actuate alarms. The 120 cps setting is the lowest
sensitivity.
< Response Time:
Response to a saturating (high intensity) UV source is typically 10 milliseconds for
the instant alarm outputs and 0.5 seconds for the area alarm outputs when
sensitivity is set for 8 cps and time delay is set for 0.5 seconds (minimum
settings).
