Fire Fighting - sematic DRIVE SYSTEM Bedienungsanleitung

6.7 AUX Output Relay
This option can be used to signal the achievement of a particular opening distance (pre-set)
or as Gong while opening (device not supplied by Sematic).
6.7.1 Space Percentage
If set, this option allows the AUX Output Relay contacts to send a signal during door
opening that relates to a pre-set distance percentage (in comparison to the total
door opening) and a signal during the door closing up to the same opening percen-
tage.
6.7.2 Gong While Opening
If set, this option allows the AUX Output Relay contacts to send a signal during the
door opening (to a device not supplied by Sematic).
6.8 Forced Closing (Nudging)
If the main lift controller operates with a disabling photocell circuit (or similar devi-
ce), after several failed attempts at closure, it is possible to command the closure
of the doors in low speed (forced closing), by closing the 15-22 connector pins
through the use of a relay (voltage free contact).
During the closing cycle the connector 21 (Gnd) and the connector 15 (+24 V) are
activated for the direct use of a 24 Vdc max 100 mA buzzer (device not supplied by
Sematic) or adequate relay.

6.9 Fire Fighting

The FIRE FIGHTING option is possible for specific installations where the main lift controller
contains the applicable functions.
For operative details of the complete lift installation, refer to the following standards:
• BS5588: Part 5: 1991
• EN81-72: 2003
• ASME A17.1: 2000
• AS-1735.1: 2001
The Fire Fighting option has a dedicated input, Kff.
When Kff switches from OPEN to CLOSED the directly or completely connected light barriers
or similar devices are ignored, as these are assumed to be devices which may be affected
by smoke or heat due to fire conditions; the reopening system can be set to either ignore
mechanical obstacle (parameter 19 = 0) or to have its sensitivity reduced (parameter 19 =
1).
Warning: the default setting is "reduced sensitivity" (parameter 19 = 1).
Change of this parameter is according to customer's choice, following careful
assessments and check of the standards required in the Country of installation.
At the end of the first closing cycle the main lift controller takes the car to the Fire Fighters'
access floor, if it is not already there.

main lift controller. Even during the opening cycle it is possible to reverse the movement
by deactivating the Ka signal and activating the Kc signal.
The Main lift controller must steadily monitor the continuous pressure of the car push-but-
tons (open door and floor call push-buttons), performed by the Fireman controlling the
installation.
During a closing cycle, the release of the floor call push-button must release the Kc signal,
insert the Ka signal and cancel the call.
During an opening cycle, the release of the door opening push-button must release the Ka
signal and insert the Kc signal.
At the end of the closing or opening run (detectable through the Lc and La signals respec-
