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.
