2.2.12
Alarm release
The smoke sensor cyclically transmits its state as well as the signal amplitude / smoke level to the AMB 32 main board. The
state of the smoke sensor is processed further on the AMB 32. If the set threshold values (alarm, pre-signal 1–3) are ex-
ceeded, the corresponding state “
Alarm
”, “
Pre-signal 1–3
” is triggered on the ASD 532.
2.2.12.1 Alarm 2
The “ASD Config” configuration software offers the possibility of also enabling an “
Alarm 2
” for the ASD 532. When activated,
that alarm is
always above
the smoke sensor “
alarm
” described in Sec. 2.2.12 (minimum 20%). If the set limit for alarm 2 is
exceeded, no additional display is actuated on the ASD 532. Alarm 2 can also be programmed on a RIM relay. Alarm 2 is al-
ways a follow-up alarm to the EN 54-20 alarm and is therefore not subject to the response requirements of EN 54-20. The set-
ting options for alarm 2 using the “ASD Config” configuration software can be found in Sec. 7.2.1 (Table A).
2.2.12.2 Alarm cascading
The “ASD Config” configuration software offers the possibility of activating a cascading scenario for the alarm release. This
means that the activated pre-signals 1 to 3 and the alarm are triggered one after the other according to the set delay times
(pre-signal delay and alarm delay).
Warning
The cascading function may not comply with
EN 54-20
requirements and may therefore only be used after con-
sulting with the manufacturer.
2.2.12.3 Isolating the smoke sensor
This function is used to place the ASD 532 in an isolated state using the “ASD Config” configuration software. This means that
test alarms can then be triggered on the ASD 532 without activating superordinate systems (FACP) (relays, OC outputs, XLM
do not trigger). When the “Isolate” function is switched on, a fault is triggered on the ASD and forwarded to the superordinate
centre. On the ASD the “Fault” LED is then continuously lit.
