Detector Maintenance Status Screens and Detector Maintenance Reports provide the
same information (such as Device Status, Compensation, Peak Value) about a detector.
This section contains descriptions of each item that appears in a Detector Maintenance
Status Screen or a Detector Maintenance Report.
1.
Device Status
The status of the detector: Normal, Alarm, Disable or Test.
2.
Type Code
The software Type Code that identifies the type of detector. Refer to “Type
Codes for Intelligent Detectors” on page 96.
3.
Custom Label
The 20-character user-defined custom label. Refer to “How to Create a
Custom Zone Label (5=
ZONE
)” on page 28.

4.
Drift Compensation (Comp:)
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.
Table 41 contains a list of the maintenance level values for each type of detector:

5.
Peak Value
(0000%)
The highest analog value reached by the detector during the past
week. The peak value slowly returns to zero.
6.
Alarm Reading (xxx%)
The current alarm reading of the detector, as a percentage of
the Alarm Sensitivity setting.

Alarm Sensitivity Setting (Ax)
The Alarm Sensitivity (x=1-9) entered in the
Detector Sensitivity Screen (Figure 51).
8.
Pre-Alarm Sensitivity Setting (PA:x)
The Pre-Alarm Sensitivity (1-9; 0 =
Pre-Alarm not used) entered in the Detector Settings Screen (Figure 51). Refer to
“Detector Sensitivity Settings” on page 79 for more information on the Pre-Alarm
sensitivity settings.
9.
Cooperative Multi-Detector Selection
A smoke detector programmed so that it
evaluates readings from nearby detectors 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
(* or Vxx)
* – Alarm Verification not programmed for this detector.
V – Alarm Verification enabled.
xx – Alarm Verification programmed for the detector; xx equals the Verification
Counter (00-99). Refer to Table 9 on page 22 for instructions on setting Alarm
Verification.
11.
Device SLC Address
The SLC address of the detector. Refer to Figure 89 on page 81
for a complete description.
