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

- Most smoke detectors are supported, including both those that are self-limiting and those that need current to be
limited in the control panel.
- Automatic detection in the zone: it is not necessary to place a resistance at the terminals or to simulate a fault if
the zone is not in use.
- Smoke detector test mode: allows smoke detectors to be tested without the DCU triggering the re alarms.

KOOLCOM
Damper Control Unit 1 channel (DCU 1CH)
The universal damper connection is a 5-wire connection:
o Contacts:
- S4+S1: can be connected inside the damper.
- S2 and S6: Are the normally open contacts of the matching limit switches.
o Motor:
- COM: common, negative (or neutral in DCU 230V)
- MOT: positive (or phase in DCU 230V)
MOT: normally not used, it is the same signal as MOT but with inverse logic.
The output connections to the damper motor are not dry contacts, but are already powered to supply the voltage needed
to power the motor: 24V o 230V, as per the DCU model.
