New detectors added to Nittan’s Evolution range

Nittan has expanded its Evolution analogue addressable range with the introduction of new detectors featuring an integral Short Circuit Isolator (SCI).

As reported by Nittan, these detectors include the EV-PY-SCI Photoelectric Optical Detector, the EV-H2-SCI Heat Detector, and the EV-PYH-SCI Photoelectric Optical & Heat Multi-Sensor, all equipped with SCI.

The heat detectors in this range are compliant with EN 54:5 and can be programmed to four different settings.

The multi-sensor model also meets EN 54 part 29 standards for combined smoke heat mode.

The new devices are designed to improve system protection in the event of external faults.

The built-in SCI is bi-directional, allowing communication with the fire alarm control panel while isolating the fault.

This technology reduces internal resistance and resets automatically once the fault clears.

Enhancements in fire detection technology

Nittan’s newly launched detectors incorporate advanced technology for improved fire detection.

According to Nittan, the devices benefit from the company’s enhanced PY smoke sensing chamber and microprocessor control.

The chamber features a spherical design that optimises light scattering and enhances fire detection performance.

An orange LED is employed, which has been shown to improve response across various types of fire.

The PY chamber is also designed to reduce the impact of dirt and dust contamination, helping to prevent false alarms.

Additionally, a fine stainless steel micromesh helps block even the smallest insects from entering the chamber, further reducing the risk of false alarms.

Broader implementation across Evolution range

The advanced technology found in the new detectors has also been integrated into other devices in Nittan’s Evolution series.

These include the EV-PY Photoelectric Optical Detector, the EV-H2-A1R Rate of Rise Heat Detector, the EV-H2-CS High Temperature Heat Detector, and the EV-PYH Photoelectric Optical & Heat Multi-Sensor.

Nittan emphasises that these devices are fully backwards compatible with previous Evolution models, ensuring they can be installed on existing systems without any issues.

This allows for seamless upgrades to take advantage of the new technology without requiring significant system overhauls.

Improvements enhance reliability and performance

The addition of integral SCI and enhanced smoke chamber technology are key features that improve the overall reliability of Nittan’s Evolution detectors.

With these upgrades, the devices provide better system protection, enhanced detection across a range of fire conditions, and reduced maintenance needs due to lower susceptibility to contamination and false alarms.

The Evolution range’s backwards compatibility ensures that the new technology can be integrated smoothly with existing systems, supporting both new installations and upgrades to older systems.
