Monitoring system
EKO-KE8
Description
The EKO-KE8 control and monitoring system is in-
tended for use in the automatic monitoring and per-
formance testing of up to eight fire/smoke dampers,
smoke dampers or pressure relief dampers with 24 V
damper motors and various types of smoke detector.
EKO-KE8 uses a built-in transformer to provide
power to both actuators and smoke detectors. The
unit has been developed using the latest technology
and meets the requirements for a monitoring system
laid down in the Swedish National Board of Housing,
Building and Planning’s General Guidelines, as well
as the applicable standards of VVS AMA 09.
Function – Indication
EKO-KE
8
is equipped with 19 LEDs that indicate the
operating status of the control unit and each of the
damper groups, plus a test button for damper per-
formance testing and a reset button to reset alarms.
When the system is starting up, EKO-KE8 detects
which damper inputs are connected. The LEDs for
“Normal” and “Alarm/Error” flash during startup.
This takes around five minutes.
Reset
Alarms or errors are reset manually using the reset
button on the front of the monitoring unit. The
monitoring system is reset automatically once
the external alarm has been reset. (Optional, see
page 3)
Automatic performance testing/time
The EKO-KE8 control and monitoring system perfor-
mance tests connected dampers 10 hours after the
unit has been supplied with voltage or after the manual
test has been conducted; the unit is then performance
tested every 48 hours. This displacement is to avoid
performance testing taking place during the daytime.
The option to conduct performance testing at other
time intervals or at other times can be enabled by con-
necting an external timer to “Trigg in” and setting DIP
switch 4 to the ON position. Once the performance
test is complete, which takes around four minutes, the
green operating LED and green LED at every damper
indicate normal position. If the test has failed, it will be
repeated once more in order to minimise failure alarms.
If this test also fails, a failure alarm will be generated.
Manual performance test
The dampers can be performance tested by pressing
the test button for automatic function test located on
the front of the monitoring unit. The internal clock is
reset for every performance test, which means that
this function can also be used to change the time the
performance test takes place.
Electrical installation
The unit is intended for permanent installation and
must be preceded by an all-pole power switch with
a gap of at least 3 mm.
