ASW45 autonomic controller of executing devices

Application

ASW45 controller is destined to set working (by no-potential contacts of the relay) executing devices such as fans, signaling device, smoke flaps.
The executing devices are set working by the module after the detection of smoke by OSD23/03 detectors. They are stopped after approx. 30 sec. from the moment the detector stops signalizing the presence of smoke.

 

 

Construction

The controlling module is constructed as a single electronic module closed in cages fitted for installation on a DIN rail. The relay's contacts circuit is insulated from the module's electronic part. Power supply wires of the operational line and wires connecting a controlled device are connected using screw terminals 2.5 mm2.
 

The principle of operation

The figure shows the state of the relay's contacts without power supply or in the operational state with NO/NC switch in NO position. The NO/NC switch is accessible after unbolting the controller on the laminate, on the print side. In NC position, the movable terminal of the relay is drawn back (contacts 10 is shorted with 11, and 13 with 14) during operational state.
When at least one smoke detector detects the presence of smoke in the air, the movable terminal is switched into the alarm state. The alarm is also signalized by "AL" control LED being lit. When the detector stops signalizing the alarm (just after an alarm signal from the detector, the module resets automatically the operational line,) the relay's contacts maintain their alarm position for about 30 sec. (the 30-second delay of turning the alarm off can be switched off – look at the specifications.)
The controller is equipped with protection against short circuit of the operational line. If the short circuit happens, the line will switch the relay into alarm and "SAB" control LED will light up.
The controller reacts to the removal of a detector out of a base or to an interruption in a detectors' line (what is called "sabotage"; in the last base 2k7 resistor has to be installed) in the same way as it reacts to a short circuit.
In the last base the terminal resistor has to be installed = 2,7kΩ.
MANUAL ON/OFF switch – any bistable switch – (joined with terminals 1 and 2) is destined to change a relay's state from an operational one into alarm for good.
RESET any monostable switch - resets detectors' alarm - it is useful especially when the function of the auto-reset is off.

CAUTION!!! Whichever option is used, the module will reset the line if alarm current in the line is higher than 200mA (simultaneous entrance of several detectors into the alarm state.)
