The main purpose of SCD vents is to vent smoke and hot and toxic gases that occur in the ceiling space when a fire occurs. The SCD flaps manufactured by Smay Sp. z o.o. have opened flaps filled with light-transmitting material, which makes them also serve as roof skylights. Another function that, with appropriate instrumentation, they can perform is that of periodic ventilation.

4. 6. SE L E CT IO N O F D R I VE S In SCD smoke vents, the primary function of the emergency opening for smoke extraction is performed by a 24V electric or pneumatic actuator. The opening function for ventilation in pneumatically operated vents is operated by a 230V or 24V electric actuator (for vents with flap dimensions up to max.
4. 8. O PT IO N AL A CC E S R O IE S 4.8.1. WIND DEFLECTORS Wind deflectors are designed to maximize the active area of smoke vents. They are used when the anticipated wind effect would reduce the active area of the smoke flap. They are profiled elements made of galvanized steel sheet with dimensions optimized by aerodynamic testing.
4.8.3. KA SECURITY GRATES The purpose of the security grating is to protect the building from unauthorised entry, through the smoke vent. The grates are manufactured in the full range of one- and two-flap vent sizes. The security grates are made using standard and special galvanised steel profiles and 1/2" tubes. The maximum pipe spacing is 180 mm.
DRIVES AND CONTROL In SCD smoke vents, the primary function of the emergency opening for smoke extraction is performed by a 24V electric or pneumatic actuator. Drive is transmitted from the actuator to the vent lid by a custom-designed mechanism, and the position of the lid is fixed by an MHV spring lock, which, in the case of ventilation actuators, locks on a "T"...

To close the "A" flap after emergency opening, do the following: 1. Remove the cartridge from the TAVE thermal release or AK alarm box. There will be an outflow of CO2 gas from the system. ATTENTION! The rapid unscrewing of the cartridge is accompanied by rapid cooling of the cylinder. 2.Unlock the actuator by moving the locking pins (see Fig.20.).

Arming and operation of the thermal release: loosen the firing pin tension screw (1 in Fig. 22) as far as it will go. 2. insert the ampoule (2 in Fig. 22) in such a way that the sharp end of the ampoule faces the nut in the ampoule holder.
5.1.5. CYLINDERS (CARTRIDGES) Cylinders with compressed CO2 are the source of energy for the basic function of the smoke vents with a pneumatic drive. They are equipped with safety valves. The connection thread is ½" UNF (extra-fine). Fig.25.CO cartridges When a cylinder with CO2 has been punctured, the gas rapidly expands and stays cool at the same time. It may result in liquid CO2 freezing inside the cylinder.
5.1.6. AK ALARM BOXES AK boxes are one of the main elements of the smoke exhaust vent control system. They enable the release of gas energy to open the flap in the following scenarios: • Manual activation – by pressing the black button, •...

5.1.7. PLZ VENTILATION BOXES PLZ ventilation boxes are important elements of smoke vent control systems with a ventilation function. They make it possible to carry out the ventilation function, and – at the same time – to keep the priority of the smoke exhaust function. The ventilation function is activated by means of a manual lever valve.

The relevant health and safety regulations, directives and acknowledged technical rules must be observed, These actuators are suitable for connection in control units provided by Smay sp. z o.o. Care must be taken to ensure compatibility when using actuators with foreign control units.
Single actuator Assembly of actuators Fig. 39. Connection diagrams for E-xxx-230 actuators. 5.1.9. PNEUMATIC SYSTEM The gas pressure in the system after emergency release may exceed 30 bar. For that reason it is very important to connect individual elements of the pneumatic system very carefully. For this level of pressure it is recommended to make the installation of certified elements: Ø6/4 copper tubes, 10000-series screw connectors.
5. 2. E LE CT R I C D RI V E S 5.2.1. CONFIGURATION Electrically operated vents come fitted with 24V actuators. The same actuator serves the function of emergency operation and ventilation. The components of the control system include: control panel, 24V - DC, manual alarm button. Emergency start-up can be achieved: Automatically - by an electrical signal sent through smoke or temperature detectors.

Installation / start-up: ATTENTION! Only specialised personnel may perform works on the control unit. Beforestarting any work, be sure to dissipate electrostatic charges. No work may be undertaken on the control unit until the power supply has been disconnected! All works must be performed in accordance with the "Installation and Operating Manual" in its complete version, which is supplied with the control unit.
Page 60
Maintenance In absence of other local regulations, all functions and indicators of the control panel and its components should be checked at least once a year during maintenance. This also applies to the examination of terminal points, connection cables, indicators and fuses, as well as the possible cleaning of various components. Be sure to check the attachment of mounting brackets, etc.
6. 1. W R S 2 B W E A T H E R S T A T I O N The required signal is transmitted by four separate potential-free switch contacts (output contacts). The contacts remain active as long as the sensor is operating, whereby the minimum operating time of the contacts is 6 min.
Page 62
Installation / Start-up Only trained persons may perform works on the control unit. Before undertaking work, ensure the dissipation of electrostatic charges. The wind sensor must measure undisturbed air (wind) flow. For this reason, the detectors must be mounted, for example, on a mast at a height of min.
