The AOP unit is designed to control fire shutters, it might also serve for control of any motors that drive louvers, shutters, gates, etc.

Depending on the number of fitted outlets, 1-3 motors of 230V voltage can be connected to the unit.
Each of the motors can be controlled separately by external buttons.

The unit is controlled by microprocessor.  In the supplied version, many behaviour parameters can be adjusted.  If these options are not sufficient, the features can be modified by means of changing the programme code.

The unit is equipped with current transformers which control the actual current, running through the motor. If motors are connected without the terminal switches outlet contacts, the unit utilizes this measuring to get information about the position of the shutter.

Power insulation is solved by means of triacs with turning off in zero; when the motor is disconnected, there is additional galvanic disconnection by relay contact.

A display can be connected to the unit, by means of which the unit can be adjusted. The display also serves to show information about the operation.

The unit contains an actual time clock and remembers accurate time of important events.

If the EPS Alarm is activated by means of 24V external voltage, GND (minuses) of both sources will interconnect.


DESCRIPTION OF TERMINAL BOARDS

Double outputs, can selected against plus or ground.

All external inputs react to supply + 24V (i.e. e.g. buttons will connect between +24V and relevant input).

Outputs OUT 1-3 switch against GND (i.e. appliance is connected between relevant output and GND).

Outputs OUT 4-12 switch against +12V (i.e. appliance is connected between relevant output and +12V).


Upper terminal boards




Lower terminal boards




Each output can be loaded with max 10W.

The total of all connected appliances must not exceed the power of the supply source (approx. 50W).




Interconnection of multiple units

If multiple units have to be interconnected (control of more than three motors), the below listed principles must be followed:

1.The GND (-), terminals of all units will be interconnected.
2. If possible, only one supply source will be used. Other sources will be left as reserve. The source delivered as standard has maximum output 50W. Input of one AOP unit is approx. 5W. All inputs of connected AOPs and the signal system (beacons, sirens) must be counted up. The sum total should not exceed approx. 80% of the maximum output of the source.
3. If multiple power supply units must be used, their terminals +24V must not be interconnected in any case.
4. The circuit of fire sensors should be energized by one source only, EPS terminals on individual AOPs will be interconnected.
5. If the individual circuits of sensors are energized from various sources, their outputs (EPS signals) must not be interconnected. In this case, external relays must be used.


Function of fuse and ERR indicator

The fuse is connected on 230V supply. The ERR indicator signals loss of 230V voltage.




FUNCTION DESCRIPTION


Prior to putting the unit in operation, the parameters have to be set - see Description of setting mode.

The unit may be in one of the below modes:

1. Normal mode

If the “EPS alarm” signal is not present, after turning on the unit will switch to normal mode. In this mode, motors react to pressing the buttons for up-and-down motion. If the motors move, the beacon signalling motion of respective shutter is active. If the safety edges and/or optical gates are on, they only control the down motion.

By simultaneous pressing the up-and-down motion buttons for 5 seconds.  The unit can be switched to the “EPS alarm” mode. It is used in case when, for some reason, the EPS switchboard does not react to emergence of fire or for test purposes.

If a display is connected (has to be connected when AOP is off), the AOP version, HW and SW version display, as well as current date and time. If any of the motors moves, instantaneous current drains of individual motors display, instead of date and time.

Normal mode is indicated by LED PWR.

• LED lights – the unit is in normal mode and energized from the system.
• LED blinks – the unit is in normal mode and energized from UPS.

2. EPS alarm mode:

The unit switches to the EPS alarm mode by activation of external input from the fire protection system (EPS) or by simultaneous pressing the buttons for up-and-down motion for 5 seconds.
The alarm mode is indicated by LED EPS.

• LED lights – the unit is in alarm mode and the signal from the EPS switchboard is active.
• LED blinks – the unit is in alarm mode and the signal from the EPS switchboard is not active.

Note: In the “EPS alarm” mode, the unit ignores the signal from the optical gate.
• If the unit switches to the “EPS alarm” mode:
o All shutters ride down automatically, and the shitter motion beacon is alighted during the time of the drive.
o The EPS warning beacon lights permanently.
o EPS siren hoots for the set period of time.
o When all shutters ride down, spraying is activated according to the set delay of the start and duration of spraying.

• If passage has to be opened up temporarily during alarm, press shortly the button for the up motion of the shutter. The shutter runs up a bit, stays in this position for a little while and then goes down to the extreme position.

• The times of moving off and waiting are set in the setting mode.

• When the signal by the EPS switchboard terminates, the unit stays in the “EPS alarm” mode and the shutters stay down.
o The EPS beacon blinks intermittently in a 5 sec interval.
o The siren does not hoot.
o The spraying is not active
o Putting the unit back to normal mode can be achieved by pressing any button for up motion.

• The unit can be set to switch to normal operation automatically once the signal from the EPS switchboard terminates, including adjustable delay time.




DESRIPTION OF SERVICE MODE

Service mode can only be activated when the display is connected.

By activation of the service mode, AOP will exit normal operation and will not react to any events on outputs throughout the setting time.

Service mode is activated by pressing the SET button for 2 seconds.

If no button is pressed for a period of 5 minutes, the unit switches automatically to normal mode.

Moving among the menu items is done by pressing the UP and DOWN buttons.
Pressing SET activates selected item.
Pressing ESC exits the selected menu.

If AOP is in the active EPS signal mode, the shutters go down immediately.  Temporary clearing of the passage by driving the shutter up and its short staying in this position can be set. Then the shutter goes down automatically again.  This function is activated by pressing the UP button or – more precisely – by pressing the ext. buttons of the shutter for the up direction.

1.2. Testing the shutter


Prior to triggering the test mode, the “time of shutter run” must be set correctly.

The test cycle is configured automatically as follows:

A. The shutter goes down for the set time of the “total time of shutter run”.
B. It is waited during the “idle time between the steps".
C. The shutter goes up for the set time of the “total time of shutter run”.
D. It is waited during the “idle time between the steps".
E. The counter is lowered by the cycles that have not been accomplished yet and this is saved in the memory.

If no button is pressed for a period of 5 minutes and the test has not been triggered yet, the unit switches automatically to normal mode.


1.2.1. setting the number of cycles
1.2.2. setting idle time between the steps
1.2.3. resetting the counter of yet unaccomplished cycles
1.2.4. triggering the test

After normal termination of the entire test, AOP stays in the test mode.

If the test is interrupted before its completion, the set value of the total number of required cycles and idle time remains saved. In addition, the value of yet unaccomplished cycles is saved. The same applies when the test is interrupted due to outage.

By next triggering of the test the last interrupted test continues. If you wish to start a new test, the counter of the already accomplished tests must be reset.
