Swegon TBLZ-1-48-2 GOLD Installation Instructions Manual

Installation Instructions, Control box for Smoke
Function with Damper Exercising TBLZ-1-48-2
GOLD
1. General
The control box for the smoke function with damper
exercising mode consists of a control unit for smoke man-
agement and a logic unit for exercising dampers, mounted
in a cabinet with a transparent cover. Wiring terminals are
provided for connection to external components.
The control box is equipped with 8 rubber cable glands for
cable entry.
2. Range of Application
The control box is used together with the TBLZ-2-49-a
smoke detectors. On receiving a fault indication, the con-
trol unit is designed to control the dampers, stop the air
handling unit and initiate an alarm.
A preprogrammed logic unit stops the air handling unit
and exercises the dampers at regular time intervals. If the
damper exercising procedure is not satisfactory, an alarm is
initiated. The connected damper actuators must be de-
signed for 230 V power.
3. Function – Control Unit, Smoke
The control unit is designed to comply with the provisions
made upon reliable fire protection together with our smoke
detectors. The unit is equipped with relay contacts for con-
trolling the dampers and fans. In addition to smoke alarms,
the control unit is equipped with service alarm and fault
alarm relays.
In the event of a smoke alarm, a red LED is lit and the alarm
relays are simultaneously de-energised.
In the event of a service alarm from the smoke detector, the
service alarm LED will flash rapidly for one minute. After
that, the service alarm relay will be energised and the LED
will shine constantly. If the service alarm on the detector
returns to normal service, the relay will be de-energised and
the LED will flash slowly: Alarm memory.
If a short circuit or a power failure occurs, this activates the
fault relay and alarm relays, at the same time as the cor-
responding LED is lit (approx. 10-second delay in the event
of a power failure). If the short circuit clears or the power is
restored, the relay will be de-energised and the correspond-
ing LED will begin to flash slowly: Alarm memory.
To exercise the relays: Press and hold down the reset button
for 5 seconds.
Continuous product development may give rise to specification changes without notice.
4. Function – Logic Unit for Damper
Exercising
The exercising cycle is activated at regular time intervals in
the logic unit or via signals from an external source trans-
mitted to the unit.
The GOLD unit stops and the dampers are exercised.
If the damper exercising procedure is not satisfactory, an
alarm is indicated on Logic module K7 and the GOLD unit
will not restart. The alarm is transmitted to the GOLD unit
via the External alarm 2 input.
Alarms can be reset on the control unit or in the hand-
held micro terminal.
5. Mounting
The control box can be secured to a wall, the air handling
unit or where required by means of four screws.
