Presence Detection Swingpath, Door Mounted; Monitored Safety Sensors; Fire Input; Relay Output - Assa Abloy SW300 Installation And Service Manual

5 How the ASSA ABLOY SW300 and ASSA ABLOY SW150 work
5.6.2

Presence detection swingpath, door mounted

When a sensor that is mounted on the swing side of a door detects an object, it will send a command
to the control unit to stall the door. If the control unit has received a short signal from the sensor
and there is still hold open time left on the control unit, the door will continue on its way open if
the object has cleared.
The inhibit/blanking potentiometer can be adjusted so that the sensor will avoid detecting a wall
or object near the full open position. Presence detection has a higher priority than presence impulse.
Note! When installed as a pair of doors the presence detection signal will stop both doors, except
for double egress doors. The behavior for double egress doors can be changed
sensor is not active in program mode OFF or manually opened door. In this OFF-mode the operator
fulfills the Low Energy Standards.
5.6.3

Monitored safety sensors

Both presence impulse and presence detection can be monitored. If a sensor becomes defective,
the operator will not accept any impulses if the presence detection sensor is defective. The door
remain in closed position and can be used as a manual door.
If the presence impulse sensor is defective, the door will remain in open position. Switching the
program selector to OFF will set the door control to low energy mode. Key impulse can be used as
impulse.
5.6.4

FIRE input

Ground and 24 VDC are used for supply of smoke detectors, see page 72.
Connection of fire alarm 12, 24 or 48 VDC is possible to connect to the FIRE input, see page
87.
5.6.5

Relay output

A potential free contact COM/NO/NC used in the below four different way, where the first three
are chosen by Parameter group (see 'Relay' in table at page 82). When indicating Error or KILL, the
error relay is resting (connection COM-NC), and when indicating Door open or closed it is activated
(connection COM-NO).
• Error indication
For external error indication, see page 91.
• KILL output
Used for distribute KILL-signal to other door sets.
• Lock output
Used for control locks with other voltage than 12/24 VDC.
• Door indication (HW-wired with jumper)
Used for indicate an open or closed position of the door. The indication position is set by adjust-
ing the inhibit/blanking potentiometer. For indication of closed door, adjust the Blanking po-
tentiometer to minimum. For indication of open door, open the door by program select OPEN
or any open-impulse, and adjust the Blanking potentiometer so that the Blanking LED is lit only
in open position (or above desired position, just like blanking).
