Increase the spring force and adjust the closing speed and also the latching action so that the door closes more quietly.

The clock relates to the speed. If the valve is turned clockwise for closing speed adjustment, for example, this increases the time that the door takes to close. Please note that in the case of fire and smoke check doors, the door closing action must be adjusted so that the door closes from an angle of 90° within a maximum of 30 seconds.

The TS 93 GSR BG (push-side) system cannot be used on the push side of emergency exit doors as DORMA does not offer a suitable carry bar which would be mandatory for such an application.

 

4. I have to operate the active leaf twice in order to close my double doors. What can I do to rectify this?

According to EN 1158, double doors must be operated so that first the active leaf and then the inactive leaf are opened. If the door is operated so that the active leaf is only opened to the extent that the inactive leaf can sweep past, and if the inactive leaf is then latched in the electro-magnetic hold-open unit followed by the active leaf, it may be that the manual release pushbutton has to be pressed twice. If the doors are operated correctly with the active leaf being opened and engaged in the electro-magnetic hold-open device first, a single operation of the manual release pushbutton is generally sufficient. The requirement to press the manual release pushbutton twice should only arise in the case of the GSR/EMF 2 system. In this case, this does not represent a defect and also has absolutely no negative effect on the efficiency of the preventive fire protection system.

 

5. Can I use the door closer on outward opening external doors?

The ITS 96 system is not recommended for external doors that open outwards and may be exposed to wind loads. DORMA does not accept any warranty responsibilities for such arrangements.

 

6. Is the ITS 96 suitable as a double-action door closer?

No. A floor spring or regular RTS transom-concealed door closer has to be used in this case.

 

7. Can a cushioned limit stay be used instead of a door stop?

The cushioned limit stay is not an overload protection device and in many applications will therefore not be sufficient as a replacement for the door stop. A door stop will, therefore, also have to be installed.

 

8. Can I also use the ITS 96 door closer as a transom-mounted unit?

The ITS 96 system can also be installed in single-leaf door sets using the transom-concealed arrangement provided that the door situation permits installation.

Manually unwind the adjustment sleeve on the active leaf channel of the push-rod clamping mechanism. Then once again apply pressure in the closing direction of the active leaf. If the system still fails to respond, replace the active leaf channel.

A floating NO contact has to be connected to terminals 6 and 10 (manual release pushbutton) of the hold-open system. If the fire alarm is triggered, the hold-open system is also released.

The Hekatron ORS 142 smoke detector is offered as a fully-fledged substitute for the ORS 132. It is 100% compatible and is also listed in the current German general building regulation approvals for the RMZ-K and S, RMZ 2, TS 93 EMR-K and S, and TS 73 EMR ( TDS 247 also).

 

12. What do I connect the manual pushbutton to? (TS 99 FL RMZ-S)

The RMZ–S has no direct connection for a manual release pushbutton. In the case of the TS 99 FL, use the RMZ-K.

 

13. How can I connect the DORMA RM to the RMZ-S?

The RMZ–S has no means for connecting RM smoke detectors. DORMA RM-S line detectors have to be used in this case as additional sensors.

The combination TS 99 FL with TS 93 GSR can be implemented without limitation and is also covered by a German building regulations approval.

In the case of the combination of TS 99 FL with TS 93 GSR, the manual release pushbutton is mandatory as it has to be possible to deactivate the free-swing function at any time via the manual pushbutton.

In technical terms, this is readily possible. Questions of official approval will have to be discussed with the local authorities (e.g. local fire brigade).

Up to 180 ° in the case of doors with flush-closing meeting stiles on the push side with a standard arm assembly, or when using an extended arm assembly for door constructions with a maximum reveal depth of 70 mm to the pivot centre and a door thickness of max. 70 mm.

 

18. When is the SR 390 used and when the SR 392?

The type of door co-ordinator - SR 390 or SR 392 – depends on the fixing location. The SR 390 is used for fixing on the pull side and the SR 392 is for fixing on the push side.

 

19. The hold-open function of the TS 73 EMF is not working. What can I do about this?

Check whether the solenoid coil of the TS 73 EMF is carrying 24V DC. If the hold-open function of the TS 73 EMF does not function even with power supplied, replace the TS 73 EMF unit. If there is no power, check the smoke detector.

 

20. What is the replacement unit for the TS 73 EMF with swing angle monitoring?

The replacement unit for the TS 73 EMF with swing angle monitoring is the TS 73 EMF without swing angle monitoring. If a swing angle monitoring function is still required, this will need to be retrofitted by others.

Check whether the actuating arm is positively engaged with the spindle. Also check whether these accessories are original DORMA products. If they are not DORMA products, it may be that there is no positive connection with the spindle (arm recess worn or otherwise disengaged). In both cases, replace the arm.
