AAF zone xx, investigation in progress
If more than one AAF zones are activated, only the first is shown in the display.
Notes:
 Maximum number of analogue smoke detectors in an AAF zone is 5.
 Smoke detectors in an AAF zone cannot be programmed as 2-unit-dependent and
not be controlled by the Alert Annunciation function.
 Only Analogue photo electric smoke detector 4401 (4301) and Analogue multi
detector 4400 (4300) can be used for AAF. If the Analogue multi detector 4400 is
used, it must be programmed as type "Two addresses", so that only the "smoke
part" of the detector can be used in AAF function.
 Max. 50 AAF zones (00-49) per C.I.E
 The sounder base 3379 has to be programmed with the trigger condition "AAF
zone alarm" (and other trigger conditions).
14.12.2 Local Alarm Acknowledgement (LAA)
The local alarm acknowledgement is the European’s equivalent of the Australian alarm
acknowledgement facility (AAM). The function is identical to the AAF explained in section
14.12.1 with different terminologies. The functionality of Panasonic’s LAAU versus Brooks
AAM are shown in Table 14 below.

One LAA zone consists of one to five analogue smoke detectors 4400 / 4401 (4300 / 4301),
one LAA buzzer (sounder base 3379) and one Local Alarm Acknowledgement Unit (LAAU).
All connected on the COM loop.
Note: All devices included in an LAA zone must be connected to the same CIE.
The local alarm acknowledgement connection diagram is shown in Figure 42 below.
