SATEL ACU-280 65
Switching the detector from passive mode to active and vice versa takes place during
periodical communication. It results in a delay whose duration depends on the frequency of
periodical communication (with the “ECO” option enabled, delay can be up to 3 minutes).
For most detectors, you can enable the “Always active” option.
According to the EN 50131-3 standard all ABAX 2 system Hold-Up devices must be
always in active mode.
The battery life time in the detectors switched permanently into the active mode is
shorter than in those which are periodically switched to the passive mode. However,
if the specific character of a detector or its installation place is such that the number of
alarms is low, switching the detector permanently into the active mode will not have
a significant effect on the battery life.
The Modbus RTU register assumes value 0x0001 (1) when the detector reports alarm
(see “Device status information”).
8.3.2.2 Wireless sirens
For sirens, changing the value of the Modbus RTU register to 0x0001 (1) will trigger
signaling. Depending on the siren:
ASP-200 – the Modbus RTU register assigned to the first position controls the acoustic
signaling, and the register assigned to the second position – the optical signaling
(see “Table of Modbus RTU protocol registers”). Thanks to a high-capacity battery,
the siren can receive transmissions from the controller at any time. Therefore,
the commands to start/stop signaling are sent to the siren immediately.
ASP-215 – the Modbus RTU registers assigned to both positions can control the acoustic
and optical signaling. This enables two different, independently triggered types of signaling
to be configured. The registers can control separately the acoustic and optical signaling or
trigger other signaling for different alarms (e.g. burglary and fire). Given its low-capacity
battery, the siren can receive transmissions from the controller during periodical
communication only. Therefore, the commands to start/stop signaling are sent to the siren
during periodical communication. Consequently, the value of the memory registers
controlling the siren should remain changed to 0x0001 (1) for longer than the
communication period.
The signaling will stop after the maximum signaling time expires, even if the register’s value
is still 0x0001 (1).
The Modbus RTU registers indicate the state of signaling (see “Device status information”).
Information about the state of signaling is sent during periodical communication.
8.3.2.3 Wireless expanders of hardwired zones and outputs
The Modbus RTU register to which the expander output is assigned (see “Device control”)
controls the operation of that output. The Modbus RTU register to which the expander zone is
assigned (see “Device status information”), indicates the state of that zone.
Information on the state of zones and commands to change the state of outputs are sent
immediately. The zone settings are sent during periodical communication.
If communication with the controller is lost, all previously activated outputs will be
deactivated after 20 communication periods.
If the ACX-220 expander is powered from a power supply connected to the APS connector,
the information about power trouble presented in the ABAX 2 Soft program has the following
meaning:
first position – power supply overload,
second position – low battery,
