Sentinel D-Box Single Fan Duct size to 5mm Performance - Airflow.1 to 1.6m 3 /s Pressure up to 65Pa Sentinel demand ventilation fan controller with lockable isolator Aluzinc contstruction suitable for Internal or External mounting Performance tested to BS848 parts 1 & 2 The Sentinel single in-line duct fans are as supplied from Vent-Axia Ltd. Manufactured from Aluzinc, Sentinel fan units are internally treated with an O class rated, BS476 part 6 & 7 acoustic foam which offers the benefits of high sound absorption, good thermal insulation properties, in addition to self extinguishing properties and resistance to ignition. Weatherproof external units incorporate an additional controller shroud. The casing includes an inclined inlet and bellmouth entry which directs the incoming air to the impeller with minimal turbulence. The result is better air management through the unit, less noise, higher efficiency and an increased performance. The housing is designed to be as compact as possible for concealed false ceiling applications and Sentinel casings are specially designed to allow the unit to be mounted via its unique mounting bracket, ensuring a quick and easy solution to installation. Impellers All Sentinel units feature a low energy, Class 1, EC/DC external rotor motor and backward curved impeller assembly specifically chosen for performance and non-overloading characteristics. The assembly is dynamically balanced to DIN ISO 194 Grade 6.3, duct size 5mm rated IP54, all other sizes IP44 according to BS EN 6529. Ball bearings are greased for life. Insulation is Class B (from - C to +6 C). All models incorporate internal electronic overload protection and soft start function. Motors are single phase 23V +/- 1% / 5/6Hz / 1ph (size - 4mm) or 4V +/- 1% / 5/6Hz / 3ph (size 5mm), (4 wire systems only). 24V DC power is provided from the controller for powering the matched range of Sentinel switches and sensors. Performance/Sound Extensively tested to BS848 parts 1 & 2. Published db(a) figures are free field sound pressure levels at 3m with spherical propagation at reference level of 2 x 1-5 Pa. The inlet/outlet sound power level spectra figures are db with a reference of 1 12 Watts. Weatherproof Typical Ordering Designation Ordering codes are similar to existing units with Suffix. /WP which denotes Weatherproof. Example: SENTS/CP/WP Accessories For duct accessories see Ducting and Fitting Section. Electrical Every Sentinel unit is fitted with a purpose designed common PCB controller incorporating a 16-character backlit alphanumerical x 2 line display with 4 button membrane keypad for fan status and commissioning set up. The enclosure is fitted with a 4-pole 1A isolator that is suitable for fitting a locking device to prevent accidental operation. 362
