'ULIW &RPSHQVDWLRQ &RPS The relative cleanliness of a detector determined
by sampling the amount of contaminants in the detector, ambient air conditions,
and the age of the detector. The COMP value also indicates if a detector requires
maintenance. Refer to “Maintenance Warnings – Three Levels” on page 34 for
definitions of maintenance levels. See Table 39 for a list of the normal level and
maintenance level values for each type of detector:
Table 39 Maintenance Levels by Detector Type
5.
3HDN 9DOXH (0000%) The highest analog value reached by the detector during the
past week. The peak value slowly returns to zero.
6.
$ODUP 5HDGLQJ [[[ The current alarm reading of the detector.

$ODUP 6HQVLWLYLW\ 6HWWLQJ $[ The Alarm Sensitivity (x=1-9) entered in the
Detector Sensitivity Screen (Figure 35). Refer to “Detector Sensitivity Settings” on
page 39 for more information on the Alarm Sensitivity settings.
8.
3UH$ODUP 6HQVLWLYLW\ 6HWWLQJ 3$[ The Pre-Alarm Sensitivity (1-9; 0 =
Pre-Alarm not used) entered in the Detector Settings Screen (Figure 35). Refer to
“Detector Sensitivity Settings” on page 39 for more information on the Pre-Alarm
alarm sensitivity settings.

&RRSHUDWLYH 0XOWL'HWHFWRU 6HOHFWLRQ A smoke detector programmed so that it
evaluates readings from nearby sensors in making Alarm or Pre-Alarm decisions.
Cooperative Multi-Detector sensing also allows the combination of ionization with
photoelectric technology in reaching an alarm decision.

* – Alarm Verification not programmed for this detector.
xx – Alarm Verification programmed for the detector; xx equals the verification
counter (00-99). Refer to Table 8 on page 7 for instructions on setting Alarm
Verification.
Alarm Verification is a user-defined global time function (set using option 7,
System) that can reduce the number of nuisance alarms. When you select Alarm
Verification for a detector, the control panel delays an alarm signal for a
user-specified time period. (The control panel ignores the Alarm Verification
Timer if it detects another alarm during the verification period.)
