5.2 – OPTIONAL ACCESSORIES
In addition to the devices featured in GD, other ones are available as
optional accessories designed to enhance the automation system and
improve its safety and performance.
PT50: Pair of 500 mm posts with one photocell on each.
PT100: (For GD10N only) pair of 1000 mm high posts with two photo-
cells.
PR1: (For GD10N only) 24V buffer battery for power supply in the event of
power failure. It guarantees at last 10 complete cycles.
GA1: OSCILLATING ARM accessory that enables the system to open
overhead-type doors
GU1: MANUAL RELEASE KIT accessory that enables the manual open-
ing of the door even in the event of power failures.
For information on the new accessories, refer to the Mhouse catalogue or
visit the website www.niceforyou.com.
5.3 – ADDING OR REMOVING DEVICES
Devices can be added to or removed from the GD automation system
at any time.
Do not add any devices until you have made sure that they
are perfectly compatible with GD; for further information con-
tact Nice Customer Service.
5.3.1 – ECSBus
ECSBus system allows device connections to be made using just 2 ECS-
Bus conductors for both the electricity supply and the communication
signals. All the devices are connected in parallel on the 2 wires of the
ECSBus itself; each device is individually recognised because a univocal
address is assigned to it during the installation.
The photocells, as well as other devices that adopt this system, can be
connected to ECSBus, such as safety devices, control buttons, signalling
lights etc.
For information on the ECSBus devices, refer to the Mhouse catalogue or
visit the site www.niceforyou.com.
The control unit recognises all the connected devices individually through
a suitable recognition process, and can detect all the possible abnormali-
ties with absolute precision. For this reason, each time a device connected
to ECSBus is added or removed the control unit must go through the rec-
ognition process; see paragraph 5.3.3 "Recognition of Other Devices").
5.3.2 – STOP input
STOP is the input that causes the immediate interruption of the manoeu-
vre (with a short reverse run). Devices with output featuring normally open
"NO" contacts (like the KS100 selector switch) and devices with normally
closed "NC" contacts, as well as devices with 8.2kΩ constant resistance
output, like sensitive edges, can be connected to this input. Multiple
devices, even of different type, can be connected to the STOP input if
suitable arrangements are made.
To do this, proceed as described in the following table 11:
NO
NO In parallel (note 2)
NC (note 1)
8,2KΩ In parallel
Note 1. The NO and NC combination can be obtained by placing the
two contacts in parallel, and placing in series to the NC contact an 8.2kΩ
resistance (therefore, the combination of 3 devices is also possible: NO,

NC and 8.2kΩ).
Note 2. Any number of NO devices can be connected to each other in
parallel.
Note 3. Any number of NC devices can be connected to each other in
series.
Note 4. Only two devices with 8.2kΩ constant resistance output can be
connected in parallel; if needed, multiple devices must be connected "in
cascade" with a single 8.2kΩ termination resistance.
Warning: if the STOP input is used to connect devices with safety
functions, only the devices with 8,2kΩ constant resistance output
guarantee the fail-safe category 3.
During the recognition stage the control unit, like ECSBus, recognises the
type of device connected to the STOP input; subsequently it commands a
STOP whenever a change occurs in the recognised status.
5.3.3 – Recognition of Other Devices
Normally the recognition of the devices connected to the ECSBus and
the STOP input takes place during the installation stage. However, if new
devices are added or old ones removed, the recognition process can be
gone through again by proceeding as follows:
1 On the control unit, press the P2 [B] button and hold it down for at least
five seconds, then release it.
2 Wait a few seconds for the control unit to finish recognising the devices.
3 When the recognition stage is completed the P2 LED [A] should go off.
If the P2 LED flashes it means that an error has occurred: see paragraph
5.5 "Troubleshooting".
4 After you have added or removed any devices, the automation system
must be tested again according to the directions contained in paragraph
3.7.1 "Testing".

5.3.4 – Photocells addition
You can install a pair of photocells (not supplied with GD) at any time.
To ensure the correct recognition of the photocells by the control unit, the
former must be assigned addresses by means of jumpers. The routing
operation is performed both on TX as well as RX (arranging the jumpers
in the same manner). Make sure there are no other photocell pairs with
the same address.
The photocells need to be assigned addresses to make sure that they are
correctly recognised among the other ECSBus devices, and in order to
assign the performed function.
The photocell of a sectional door automation system can be installed fol-
lowing that shown in fig. 82. Refer to Fig. 83 for overhead door automa-
tion systems.
Photo E and Photo F are used in installations that require the complete
protection of the automation system, also in opening.
The recognition phase must be performed after installation or the remov-
al of photocells as described in paragraph "5.3.3 Recognition of Other
Devices".
