GIRA 233602 Smoke detector (Ø x H) 12.5 cm x 48 mm

Twice as safe through heat and scattered light measurement – now with Q-label

The new GIRA Dual Q smoke detector has two detection methods which provide double the security. Visually, it detects small smoke particles before it becomes explosive and dangerous for humans. In addition, heat sensors measure the temperature changes in the room: This enables different types of fire, such as flammable liquids, to be registered faster and detected reliably.

The alarm behavior can also be better controlled in applications where there are unavoidable interference such as kitchen steam, dust or electrical interference pulses. The lifetime of the permanently installed battery is at least 10 years. For even greater safety, comfort and economy, the functionality of the GIRA Dual Q smoke detector can be networked and extended to optionally available devices.


Q-label for increased quality

Awarded the Q label, the GIRA smoke detector Dual Q fulfills enhanced quality criteria according to the vfdb directive 14-01 and DIN EN 14604:2009-02. The Q stands for tested longevity and reduction of false alarms with simultaneously increased stability, e.g. against external influences.


Detection of smoke by stray light measurement

The GIRA Dual Q smoke detector detects smoke emissions using the principle of photoelectric stray light measurement with processor-controlled signal analysis. An LED in the smoke chamber emits light rays. Penetrating smoke breaks these rays of light and steers them to a receiver diode. The alarm goes off.


Quick detection of fire type by heat measurement

The Dual Q smoke detector detects heat development by means of an additional thermal sensor: This means that different types of fire, such as a flammable liquid fire, can be registered faster and detected reliably. The alarm behavior can also be better controlled in applications where there are unavoidable interference such as kitchen steam, dust or electrical interference pulses.


Testing of devices without dismantling

The GIRA wireless diagnostics tool enables the inspection of GIRA Dual Q smoke detectors from the floor or from outside the room, e.g. from the staircase. It consists of the radio diagnostics USB box and the radio diagnostics software in German and English. The data transfer takes place without dismantling the device.


Module interface for networking with optional radio, relay or KNX module

For even more safety, comfort and economy, the functionality of the GIRA Dual Q smoke detector can be expanded with optionally available devices: Connection of up to 40 devices by wire or radio, verification of the function from the floor or even from outside the room, integration into the KNX system or connection of external alarm devices.


Battery failure warning (30 days)

The GIRA smoke detector Dual Q continuously checks its smoke evaluation and checks the battery voltage. Any errors are displayed by means of a malfunction signal (signal tone and LED). The GIRA Dual Q smoke detector announces a necessary change of device for 30 days in advance. During this time, the device is fully functional.


Disassembly lock

The GIRA Dual Q smoke detector is also attractive for use in kindergartens, commercial and rental properties thanks to its protection against dismantling. The disassembly protection can be optionally activated on the mounting plate. After that, the lock can only be opened with one tool, for example for maintenance work.


Usage places

The GIRA Dual Q smoke detector can be installed in any room, thanks to dual technology, even in the kitchen and bathroom. This means that the optical smoke detection can be switched off for 15 minutes by means of a photoelectric scattered light measurement, if it once steams extremely from the cooking pot. The heat sensors continue to provide reliable fire protection in the room.


More secure with certificate: Recommendation for the installation of smoke detectors

Smoke detectors are life savers and therefore, they must fulfill their functions reliably in the event of a failure. To do this, ensure that they are installed correctly. For the professional installation of smoke detectors in accordance with DIN 14676 a proof of the technical competence of the service providers is provided, who carry out the planning, installation and maintenance of smoke detectors.


Installation instructions

If mounted in the center of the room under the ceiling, the GIRA smoke detector has optimum detection characteristics. If this is not possible, a minimum distance of 50 cm to the wall should be kept. A smoke detector can monitor a room with a maximum area of 60 m² up to a maximum height of 4.50 m. The places where smoke detectors should be positioned to provide minimum protection are different from the house or apartment depending on the design. In single-story apartments, at least the corridor frequently used in the event of a fire is a minimum requirement. In buildings with several floors, the corridors of each floor are added. However, all rooms should be equipped to provide optimum protection.
