Control and monitoring unit
MANUAL

2 / 12MANUAL
DESCRIPTION
The KSUB is a control and monitoring unit for venlaon system re
protecon, designed to control re dampers and an air handling unit (fan).
It regularly monitors the end posions of the damper.
The KSUB can be used as a stand-alone unit or as a slave unit in a network
with the SUSA or KSUA master unit.
4 re dampers in 2 damper groups
2 smoke detector loops (max. 5 per loop)
Manages 1 air handling unit (fan)
48 hour or 7 day interval for damper test
Input for an external re alarm or night mode
A-alarm and B-alarm relay (re alarm/sum alarm)
Integrated transformer 230/24 VAC
KSUB LIGHT
The KSUB Light is a version of the KSUB which only has connecons for:
Dampers (DAMPER 1 & 2)
Fire alarm (EXT)
Network connecon to SUSA/KSUA (IS-BUS)

GENERAL SYSTEM OVERVIEW
A typical example of network mode involving the SUSA master unit and
slave units is presented below. Follow the instrucons to install the KSUB as
a stand-alone unit or as a slave unit for the SUSA or KSUA.
You can also visit our website oncontrol.se to use our product selecon program.
ACCESSORIES
KBOX
The KBOX connecon box makes it much easier to connect the actuators to
the control unit. There are labelled terminals and an integrated motor test
buon.
It is also easy to connect two actuators to a damper group (parallel connecon).

Wiring
The wiring is described in one of the tables below
depending on whether the unit will be installed as a
stand-alone unit or in network mode (slave unit for the
SUSA/KSUA):
Wiring for stand-alone mode on page 6
Wiring for network mode on page 7

The smoke detectors are connected with twisted
pair (telephone type) cable, with no parcular
requirements in terms of cross-seconal area.
The damper motor can be connected with EKKX
1×4×0.5 for example.
One damper per damper group max. 100 metres
Two dampers per damper group max. 50 metres
The IS-BUS network can be connected with
FKAR-PG 2×0.5.

Fire dampers are connected as illustrated above,
with up to two dampers per damper group.
The bypass/pressure relief damper type with spring
return to the open posion is only supported if the
KSUB is used as a slave unit and the damper type is
connected as a re damper. The damper types must
not be mixed within the same damper group.
IMPORTANT!
If a single damper group is connected
in stand-alone mode, DAMPER 1 must
be used with jumper 4 ON.

Fire damper with 24 VAC motor, opened by spring to the safe posion (open).
Normal mode Means that venlaon dampers are open and evacuaon dampers are closed.
Night mode All damper types are closed. Used for example when the venlaon system is shut down to
save energy. The re damper is moved to the safe posion and opens when the NIGHT input
closes again. Damper tests can take place during this me.
Stand-alone mode The unit is not connected via the IS-BUS network to a master unit. It is instead completely
stand-alone and alarms are indicated via LED and the voltage-free changeover relay. The
jumper panel is used for conguraon.

FUNCTION DESCRIPTION
AOPERATION
(OPER.)
Green LED showing that the unit is receiving power and indicang day/night mode or
communicaon.
Constant = day mode.
Slow ashing = night mode.
Rapid ashing = communicaon via IS-BUS.
BERROR (ERR) This LED uses three dierent ashing sequences to indicate three dierent alarms.

Check that:
The terminang resistor is correct in the last detector of the loop with the problem. It
should be 2200 Ω, 0.6 W.
If the input is not used, a resistor of 2200 Ω must be installed to replace the detectors.

The indicaon is delayed by one hour to prevent false alarms. When the alarm is reset, the
delay is deacvated to make it possible to conrm immediately that the alarm has been
cleared.
Check that:
There is no dirt on one or more detectors.
Indicated by a yellow LED on the aected detector if the detector has a service alarm

If a single damper group is connected, DAMPER 1 is used for the connecon and jumper 4 is ON.
Connected DAMPER (1, 2) groups indicate NORMAL (green).
Perform a manual (E) damper test and check that the relevant DAMPER indicates OFF
