7. Alarm Sensitivity Setting (A8) The Alarm Sensitivity (x=1-9) entered in the Detector

Sensitivity Screen.

8. Pre-Alarm Sensitivity Setting (8) The Pre-Alarm Sensitivity (1-9; 0 = Pre-Alarm not used)

entered in the Detector Settings Screen. Refer to “Detector Sensitivity Settings” on page 101

for more information on the Pre-Alarm sensitivity settings.

9. 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. See “Modify an Addressable Detector Point” on page 20 for instructions on

setting Cooperative Multi-Detector Settings.

* – Multi-not used.

A – combines the detector’s alarm decision with the next address above.

B – combines the detector’s alarm decision with the next address below.

C – combines the detector’s alarm decision with the next address above and the next address

below.

10. Alarm Verification (*)

* – 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). See “Modify an Addressable Detector Point” on page 20 for instructions on setting Alarm

Verification.
