GIRA 1288 00 Video Control Device

Safety information

Electrical devices may only be installed and connected by a qua-lified electrician. Serious injury, fire, or damage to property is possible. Read and observe these instruc-tions completely. These instructions are an integral component of the product and must remain with the end customer.

Intended use

Provision of bus voltage (26 V DC ± 2 V) for the door communication system
Control of up to 15 color cameras (5 video door stations and 10 DCS camera gateways),
Power supply of
up to 31 video devices (e.g. 28 home stations, 2 door stations with a color camera, 1 DCS switching actuator)
up to 70 audio devices
and up to 2 color cameras (more with additional power supply)
Call-button illumination (max. 15, the number of call-button illuminations that can be supplied with power depends on the system size and the number of home stations operated in parallel)
Provision of the door opener control incl. power supply (12 V AC, 1,1 A) for the door opener.
Activation of the entire door communica-tion bus system’s programming mode.
Electronic overload, short-circuit, and overtemperature protection.
“Operation” LED indicator (mains voltage), overload/short circuit,
Adjustable door opener activation time.

Assembly

For drip and splash-proof installation, mount the control device on a top-hat rail in the distributor. The mains and bus connection is made using screw terminals. The mains connection must be made using an all-pole mains switch with a contact opening of at least 3 mm. The functional earth must be connected using a distributor block. The control device’s ventilation slits must not be obstructed.

Electrical connections

L, N
Mains connection terminals L and N (AC 230 V, 50 Hz).

(Functional Earth)
A functional earth is connected to this terminal for functional reasons. Connect the earth’s potential to the earth’s terminal with a suitable line (not a green/yellow line).

Bus
Power supply output of the Gira door communication bus with a regulated DC voltage (26 V DC ± 2 V, 700 mA).

(Door opener output 230 V~/max. 2 A)
A door opener that cannot be connected to the “12 V~” terminals due to its electrical values (e.g. very low ohm or 24 V) can be connected to the equipotential-bonding relay contact with an external power supply (230 V~, max. 2 A).

Remove blank plug
Before connection, remove the blank plug from the terminal.

12 V~ (door opener output 12 V~)
The 12 V~ output is used to supply power to and control the door opener (8–12 V, max. 1.1 A).

No permanent 12 V output
Power is not continuously supplied at the door opener output. The 12 V supply at the door opener output is only active for the door opener time specified on the setting controller.

Start-up

Door station – home station assignment

Door opener – door station assignment:

Further information
Further information on application scenarios, system limits, topologies, installation,n, and start-up can be found in the “System basics for door communication”

in the Gira download area:

Operation

“System program.” button If the “System program.” button is pressed for 3 s, the door communication system is switched to programming mode. The yellow LED next to the programming button flashes to indicate that the programming mode is active.

“Door-opener program.” button
The “Door-opener program.” button has two functions:

Switch on door opener programming mode: If the “Door-opener program.” button is pressed for 3 s while the system is in programming mode, the door opener programming mode is activated. The yellow LED next to the “Door-opener program.” button flashes to indicate that the door-opener programming mode is active.
Operation of the connected door opener. Briefly pressing the “Door-opener progr.” button activates the door opener for the set door opener time. The yellow LED next to the “Door-opener program.” button lights up during the switching time.

“Door-opener time” setting controller
The activation time of the door opener can be continuously adjusted using the “Door-opener time” setting controller. The adjust-ment time ranges from 1 s to 10 s. The potentiometer can be adjusted using a screwdriver with a 3 mm blade.

Indicators

“Operation” indicator
During fault-free normal operation, only the green “Operation” LED lights up. It signals that the device is being supplied with mains voltage.

“Overload” indicator
The video control device has electronic overload protection that protects the electronics of the control device against short circuits and overload on the bus line. The overload protection is activated if the bus line is short- circuited due to an installation error, for example, or if too many bus devices/bus loads have been connected. The red “Overload” LED signals both a short circuit and an overload. The length of time the LED flashes corresponds to the time that the bus voltage is switched off in the event of an error. After the error has been corrected, the LED continues to flash for up to 5 s. In case of a permanent overload (or short circuit), the bus voltage is switched off for approx. 180 s after the third overload is detected. During this switch-off phase, the “System program.”, “Door-opener progr.” and “Overload” LEDs flash. After the error has been corrected, the LEDs continue to flash for up to 180 s.
