Intelligent Wireless Optical Smoke Detector c/w Base and Batteries (HFW-PA-01)

The HFW range of Intelligent Detectors come in three variants; Optical, Thermal and Multi Criteria. All devices are compatible with the loop Translator Modules and Expander Modules.

Key Features

• Bi-directional wireless communication
• Self optimising wireless amplitude and frequency
• Automatic wireless channel hopping
• Fully Intelligent
• High reliability and sensitivity
• Flexible on site device adjustment
• Makes additions to existing wired systems easy and cost effective
• Utilises standard low cost lithium battery technology
• Fully monitored primary and secondary power sources

Power Supply

• Dual 3 V Lithium batteries: 1 x Primary CR123A (1.2Ahr) 1 x Secondary CR2032A (0.24Ahr)

The Translator Module monitors the condition of both batteries and shows a discharge of either using an internal LED indicator as well as a fault indication at the Translator Module and Fire Detection Control Equipment.

Indication

- A bi-colour (red and green) LED indicator provides 360 degree cone of vision displaying information
regarding the operational modes and condition of power supplies.

- The indicator also provides information during the programming of the device regarding the wireless signal strength allowing defining of stable operating locations when installing the unit.

Additonal Information

• The detectors parameters are programmed via the Translator Module either by a wireless keypad or a PC link.
• The Translator Module automatically manages detector radiation power depending on the device communication quality.
• Detectors automatically adjusts its frequency and radiation in accordance with the signal quality received from the Translator Module.

Design

• The patented smoke chamber ensures optimal smoke sensitivity from all directions. Whilst the double dust trap provides the chamber with increased protection from airborne contamination and background illumination (HFW-PA-01 & HFW-MA-01 models).
• Each detector is fitted with a reed switch facility allowing testing using a magnet.

Algorithm

• Adaptive signal processing helps with the elimination of false alarms.
• Temperature compensation gives reliable and steady operation in low and high temperatures and compensates for differences in temperature between the Translator and field device locations
