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 management 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 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 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 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. 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 handheld 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. * Shielded cables are recommended for installation to eliminate the risk of inductance occurring between parallel wires. If additional smoke detectors are used, they must be connected in series. (Install termination resistor on the last smoke detector.)

External Control – Exercising
GOLD Unit
B7: B7: Smoke Smoke detector detector
Function: If in-duct Smoke detector B7 trips, an alarm is transmitted to the external fire alarm input in the GOLD unit. Damper actuator MG7 is controlled via Control Unit B6. If the smoke detector becomes fouled, a service alarm is initiated in Control unit B6 and is transmitted to the GOLD unit via the external Alarm 2 input. Alarms can be reset on Control unit B6 or in the Handheld micro terminal P1. Damper exercising: The exercising cycle is activated at regular time intervals in Logic unit K7 or via signals from an external source transmitted to Logic unit K7. 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 External alarm 2. Alarms can be reset on Control unit B6 or in the Handheld micro terminal P1.

Menu for damper running time. Indicates the time required for the damper to open and close. If the damper has a longer running time, these parameters must be altered. Press OK Increase or decrease the running time by pressing + or –. Confirm by pressing OK. Press the - button to highlight the next value.
Menu for total time for exercising cycle. If the damper exercising procedure is not satisfactory, the alarm is delayed during this period. The air handling unit is restarted immediately when the exercising procedure has been accepted.
