Installation Instructions, Control box for Smoke
Function with Damper Exercising TBLZ-2-48-2
GOLD/COMPACT
1. General
The control box for the smoke function with damper exercising mode consists of a control unit for smoke management, a logic unit and a transformer for exercising dampers, mounted in a box with a transparent cover. Necessary
wiring terminals are provided for connection to external
components.
The control box has knockout holes for cable entry
through grommets.
2. Range of Application
The control box is used together with the TBLZ-2-49-a
smoke detectors. On receiving a fault indication, the control 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 designed for 24V AC 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 controlling 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 corresponding 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 corresponding LED will begin to flash slowly: Alarm memory.
To exercise the relays: Press and hold down the reset button
for 5 seconds.
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 transmitted to the unit.
If the damper exercising procedure is not satisfactory, an
alarm is indicated on Logic module K7 and the AHU will
not restart. The alarm is transmitted to the AHU via the
External alarm 2 input.
Alarms can be reset on control unit B6 and in the air handling unit’s 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.

If several damper actuators for smoke are installed in each
alarm section, they must be connected in parallel in a
terminal box.
The end position contact senses when the damper actuator is de-energised. In this position it should be connected
as normally open.
If smoke damper actuators are divided up in sections (various fire compartments), remove the jumper between the
contacts of each section concerned to enable the indication of separate alarms.
Function:
In the event of smoke detector B7 in the duct tripping, the
alarm is forwarded to the air handling unit, external fire
alarm. Damper actuator MG7 is controlled via control unit
B6.
When the smoke detectors become dirty, a service alarm
is initiated in control unit B6 and is forwarded to the air
handling unit via external alarm 2.
Alarms can be reset on control unit B6 and in the air handling unit’s hand-held micro terminal.
* Shielded cables are recommended for installation to
eliminate the risk of inductance occurring between parallel
wires.
Damper exercising:
The exercising cycle is activated at regular time intervals
in logic module K7 or via signals from an external source
transmitted to K7.
The air handling 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 air handling
unit will not restart. The alarm is transmitted to the air
handling unit via external alarm 2.
Alarms can be reset on control unit B6 and in the air handling unit’s hand-held micro terminal.
If additional smoke detectors are used, they must be connected in series. (Install a termination resistor on the last
smoke detector.)
