8 33758 Schloß Holte Stukenbrock When connecting chain drives and third-party drives, the separate circuit diagrams in the Appendix must be observed. If no model JM DC... motor opener with its associated load disconnector is connected to a line, then the line must be terminated by means of a 33 kω resistor. This resistor is used in monitoring the motor line for line breaks. A 33 kω terminal resistor is likewise required when connecting third-party drives with switch-off by means of limit switches in the end positions. This is installed on the motor via the + and terminals Determining the cable cross-sections When 24 V DC motor openers are used, the length of the motor supply cables is limited due to voltage drop. In such cases, the maximum permissible cable length is determined by the number of motors operated on a motor line and by the cable cross-section. The following table shows the maximum permissible cable length for model JM DC -... motor openers depending on the number of motor openers and the cable cross-section: 24V / 0,8A on: Number of motors in a group Number of wires required (in 24V / 0.8A addition to earthing conductor) 1 2 x 1,5mm² x 2,5mm² x 4mm² x 6mm² x 1,5mm² x 2,5mm² x 4mm² x 6mm² x 1,5mm² x 2,5mm² x 4mm² x 6mm² x 1,5mm² x 2,5mm² x 4mm² x 6mm² x 1,5mm² x 2,5mm² x 4mm² x 6mm² 80 Maximum permissible simple cable length to the last motor [m]

12 33758 Schloß Holte Stukenbrock The manual detectors (smoke and heat vent switch 6 and/or smoke and heat vent switch 7) make use of 7-strand or 3-strand cables, depending on the pushbutton type. As in the motor line, a 33 kω resistor must also be connected in the last detector for the purposes of cable monitoring. The smoke and heat vent switches are divided into two types according to their various displays and functions: Smoke and heat vent switch 6: Trigger smoke and heat vent pushbutton Reset pushbutton Close pushbutton Trigger LED Fault LED Mode LED Smoke and heat vent switch 7: Trigger smoke and heat vent pushbutton Trigger LED The following illustrations show the two smoke and heat vent switches: SMOKE VENT Operation Break glass OK SMOKE VENT Break glass Trigger Trigger!

A wind/rain detector system can be connected to the for priority closing of the opening devices in ventilation mode. The above illustration shows the connection of the WRM 401/B wind/rain detector system and the connection of the RM 301 rain detector. It is also possible to connect a third-party product, provided that it is equipped with a floating make contact. To ensure proper functioning of the wind/rain detector, the technical documentation of the wind/rain detector must also be observed Relaying of alarm and fault states Two relays, each with a floating changeover contact, are provided to pass on the alarm and fault state (see illustration) Fault alarm 33k Relay K1 (terminals 5, 6, 7) is used for the floating relay of faults. Relay K2 (terminals 8, 9, 10) is used for the relay of alarm signals. Both relays can switch over at 230 V 3 A. The terminals are of the plug-in type, which simplifies removal for forwarding purposes. K1 K2 In the normal state, the fault relay is picked up; it drops out in the event of a fault.

15 1 Jofo Pneumatik GmbH Schloß Holte Stukenbrock Configuring the ventilation groups The has a total of 4 ventilation groups (4 motor lines), which can alternatively be connected by jumpers. Small jumpers are located underneath the motor output terminals for this purpose. A total of 3 jumper pairs are provided for the ventilation group arrangement (see illustration below). If the left jumper pair is inserted horizontally, motor outputs 1 and 2 are connected to form a ventilation group. If the centre jumper pair is inserted horizontally, motor outputs 2 and 3 are connected to form a ventilation group etc. If all jumper pairs are inserted horizontally, all motor outputs are connected to form a ventilation group. The ventilation pushbuttons, when ventilation groups are combined, are connected to the terminals of one of the combined ventilation groups provided Gruppe 1+2 Gruppe k 33k 33k 33k 33k Gruppe 2+3 Jumper F3 F4 F5 F Cable types Electric cables must always be installed in accordance with VDE 0108 (smoke extraction systems). Type NYM cables installed under plaster may be used. When installing cables on top of plaster, types with insulation stability or function stability (FE 180 / E 30) are recommended. Exception: The ventilation pushbutton cabling! All cable types must always be approved, however, by the responsible building authorities, fire safety authorities, or the local fire brigade.

16 33758 Schloß Holte Stukenbrock Functional description The is a smoke and heat vent control unit with an emergency power supply for 72 hours in the event of a power outage. It is used to open and close electric motordriven smoke vents in the event of a fire, and also for everyday ventilation. The functional description will be kept quite general at this point. The functions of the individual operator control and display elements will be described in more detail in the next section. A distinction is made between two basic operating modes: 4.1 Smoke and Heat Vent Operation In the event of a fire, a smoke and heat vent alarm is triggered, causing the connected opening elements to open. Smoke and heat vent operation always has priority over ventilation mode; the batteries help to ensure that after 72 hours of power outage the system can still be opened twice and closed once (smoke and heat vent operation). It can be triggered manually by pressing the Open smoke and heat vent pushbutton on the external smoke and heat vent switches, or automatically when one of the automatic detectors is triggered. Triggering is also possible when a power outage has lasted longer than 72 hours. When necessary, or when the fire brigade so desires, the connected opening elements can be given a Reset command and then closed again. To do this, first the smoke and heat vent alarm is acknowledged by pressing the Reset pushbutton on the smoke and heat vent switch or on the board. Then the opening elements can be closed again by pressing the Close pushbutton on smoke and heat vent switch 6, the individual ventilation pushbuttons, or the Close pushbutton on the board. Smoke and heat vent operation has priority over ventilation mode, i.e. operation in ventilation mode is not possible during a smoke and heat vent operation alarm. 4.2 Ventilation mode The connected opening elements can be opened and closed by means of the individual ventilation pushbuttons. The distinguishes between two different types of ventilation, which can be set by means of a slide switch on the board. When the switch is in the Continuous position, pressing the Open pushbutton once moves the motor to the Open end position, and pressing the Close pushbutton once moves it to the Closed end position. Both pushbuttons can be pressed simultaneously to hold the motor in an intermediate position. If the slide switch is in the Push position, the motor can be moved in the Open direction only so long as the Open pushbutton on the ventilation pushbutton is held down. If the Close pushbutton on the ventilation pushbutton is pressed, the motor moves to its Closed end position (even if the slide switch is in the Push position). If a wind/rain detector is connected, its function has priority over normal ventilation mode, i.e. in the event of a rain/wind alarm the connected opening elements are closed automatically, and can only be opened again manually after the rain/wind alarm has dropped out. Operation in ventilation mode is not possible during a power outage. No ventilation is also issued when a battery undervoltage is detected (the battery cannot allow additional ventilation because otherwise operation for 72 hours under emergency power would no longer be possible). This is signalled by means of a red LED on the board.

17 33758 Schloß Holte Stukenbrock Commissioning Commissioning is possible once all necessary external devices have been connected, the wiring has been double-checked, and the batteries have been charged. First the power supply must be ensured. Only when the batteries have been connected can the mains voltage (230 V AC) be switched on; the green Mode LED s on the board and on smoke and heat vent switch 6 light up. When connecting the batteries, it is of the utmost importance to ensure the correct polarity. Connecting the batteries incorrectly will result in immediate destruction of the board!
