Functional sequence of operation
The operation of the ASD 532 aspirating smoke detector in normal mode (after commissioning) is limited to switching on/off or
to resetting a triggered event (alarm/fault). Operation is generally via the FACP, with input of the “Zone On/Off” and “Reset”
functions (on “Reset external” input of the ASD 532).
Events triggered on the ASD 532 can be reset locally using the “
Reset
” key on the control unit or by briefly actuating the “Re-
set External” input. The reset is possible only if the triggering event is no longer pending (e.g. smoke sensor no longer has
smoke). The application of a continuous signal at the “Reset external” input also deactivates (switches off) the ASD 532 (see
also Sec.s 2.2.6 and 6.6.2).
Notice
A local reset does not reset a higher-order FACP. It may also happen that the reset in the ASD 532 triggers a
fault in the superordinate line of the FACP.
To aid commissioning the ASD 532, there are two 7-segment displays, an alphanumeric display, and two keys (“UP” and “OK”)
inside the device on the AMB 32 Main Board. These elements provide a type of rotary switch function, i.e. displays and posi-
tions in the range
A00
to
Z99
may appear.
These elements are used when commissioning the ASD 532. Device settings for predefined system limits can also be called
up –
EasyConfig
. These pre-defined positions are stored with normative values for response sensitivity, airflow monitoring
(
LS-Ü
) and pipe configuration. They also contain positions which allow deviations from the normative limits with regard to air-
flow monitoring. The
EasyConfig
process allows the device to be commissioned without the “ASD Config” software. If system-
specific programming has to be carried out (e.g. after a calculation with “ASD PipeFlow” or when programming RIM 36), the
“ASD Config” configuration software must be used.
