KOOLCOM
KOOLCOM fire damper monitoring system.
Introduction
KOOLCOM is an electronic control system for re dampers that allows
the condition and functionality of each re damper to be periodically and
automatically monitored and checked. It can also close the dampers
should the re alarm be activated.
While this system is capable of being managed by a BMS (Building
Management System) system, KOOLCOM can also work in Standalone
mode, i.e., operate autonomously without the need for a BMS or any
external maintenance personnel.
HUB Design Concept
KOOLCOM is the only system on the market whose installation
is based on the HUB design concept (a central communications hub).
This allows:
- Control of up to 31,616 re dampers.
- Greater data communication speed (32 times faster than systems
without this arrangement).
- Simple alarm wiring.
Technical specications
- Control electronics for 1 to 4 re dampers (DCU)
- Control electronics for 24 V (AC and DC) and 230 V AC dampers
- Autonomous or interactive with the central re alarm system
- Programmable periodic checks
- Supply fan actuator, congurations for extract fans and smoke
extract by means of an external contact.
- MODBUS Communication. Adjustable velocity. Integrated
bus terminator.
- Alarm input/output. Dry contact.
- Test mode for smoke detectors
- Segregated graphic console.

System components.
Damper Control Unit (DCU 1CH)
DAMPER CONTROL UNIT 1 CHANNEL (DCU 1CH)
DCU 1CH (Damper Control Unit, 1 Channel) are devices used to send commands and
supervise motorised re dampers, which by means of commands sent through the
ModBus allow them to be automated and controlled.
They are integrated in the KOOLCOM re damper control and supervision system. This
system is completed with KHUK units (KoolCom Hub Unit KoolAir), which allow DCUs
(1CH or 4CH) to be grouped in sets of 32 units, and connects the colour, touch screen
consoles.
Each DCU 1CH has:
• 1 input for a conventional smoke detector (zone).
• 1 output for re damper in two available formats:
• Direct connection for Belimo motors.
• Universal motor connection.
• 1 power input.
• 1 ModBus connection.
• Models:
• 24V (AC/DC) - 100-DCK300: For 24V re damper motor.
• 230V AC - 100-DCK400: For 230V power supply damper motor.
The DCU contains the control electronics for the di󰀨erent re dampers. KOOLCOM o󰀨ers two models which allow either 1,
or up to 4 dampers to be controlled by the same device.
Materials:
− Casing: ABS (-40°C | 100°C).
− Cable inlet: Nylon 6/6 and TPE.
Waterproong:
− Box: IP 54
− Cable inlet: IP 67/68

KHUK AND DCUs
Three wires with polarity that connect exclusively to the DCUs. The KHUK contains the MODBUS termination. By inserting
the MBUS TERM bridge into the furthest DCU, the two necessary terminations are achieved. Di󰀨erent DCU models (DCU-
1CH and DCU-4CH) can be mixed in the same bus.
For the modbus wiring, RS-485 cable must always be used; available from various manufacturers.

MOD-BUS Topology
Daisy Chain topology must be used wherever possible. If this is not feasible at any point, a Backbone with stubs can also
be used.
In cases where backbone with stubs topology is used, the stubs should be as short as possible and never exceed 10
meters.

KHUK and alarms
Fire Alarm and Reset Input: When the +24V from the
source is received at the alarm input, the KHUK considers
there to be a re alarm external to the system (not activated
by the smoke detectors). It will activate the alarm input on
each DCU connected to the KHUK, resulting in the closing
of all connected dampers.
N.O. Alarm Relay Output: Volt-free contacts with a
maximum switching capacity of 8Amp, which are closed
when any DCU informs the KHUK of the occurrence of an
alarm. They are usually connected to the central re alarm
system, which awaits the closure of these contacts.

Accessories
This section describes the accessories that may be necessary during installation.
Cable MODBUS
This depends on the specic conditions of each installation,
especially the level of electrical noise in the zones which the wiring
passes through, the distance to be covered and the chosen connection
speed. We recommend that RS-485-specic cable always be used.
In general the cable specications will comply with:
- be twisted pair (or pairs) cable.
- have at least three conductors + screen.
- nominal impedance: 100-120 ohms
- AWG24 (section 0.2mm2, diameter 0.51mm)
- screened
MODBUS Extender/Isolator
Optical MODBUS Extender / Isolator. In cases with long cable runs,
or even to facilitate easy fault detection in the installation, this allows
the connection wiring between the KHUK and the di󰀨erent DCUs to be
expanded and isolated.
USB-MODBUS Interface
Allows the KOOLCOM system and a computer to be connected if
there is no integrated RS485 port.
