Detector APD-12R Ariak

These detectors have a housing. Inside the chamber there is a bimetal (two metal strips of different materials). Hot air affects the bimetal and the heat causes its contacts to close and the detector to operate. These detectors are for places such as kitchens, motorhomes and. . . It is convenient. In the case of electrical appliances whose onset of fire is accompanied by the emission of heat, this type of detector detects the heat caused by the occurrence of fire in the very first moments and announces the closure of the relevant electrical circuit to the control panel and planning actions. It does this automatically and fire alarms sound to alert people to the incident. This type of detector basically includes two types (fixed and temperature sensitive).

The basic types of these detectors work in such a way that these detectors are used due to the expansion of a metal strip to feel heat, which in its simplest form, this strip bends when it reaches a predetermined temperature for the effect of expansion and By rejecting the current of electricity, they activate the announcers. The new series uses a small electronically calibrated resistor as a temperature detector instead of metal strips.

The operating temperature of this type of detector is usually around 65 degrees. Heat detectors in fire alarm systems are especially suitable for environments that normally contain smoke (such as kitchens, boilers, laundries and car parks. To use these detectors, the maximum coverage, the maximum distance between the wall and the detector, the distance He noticed between the detectors, the protrusions on the roof, and so on

- Detection of smoke-free, smoke-free types with invisible particles, with photo smoke detectors (APD) and ionization (ASD)

- Detection of types of high-flame and exothermic fires with different temperature rise rates, with constant temperature (AFH) and hybrid (ACH) detectors

- Combining the capability of smoke and heat detectors in fire detection in the form of multisensor detectors in two types of photons (AMD-P) and ionization (AMD-I)

- Detection of municipal and capsular (liquefied) and flammable gases with AGD detectors

- 24V detectors for use in conventional fire alarm systems

- 12 and 48V output contact detectors for protection and telecommunication systems

- Displays the detector status, for normal and fire mode
