The vitiated air shall beextracted from each area via ductwork as shown. All necessary ductwork fittingsand ancillaries shall be allowed for by the mechanical sub extract fans shall be operated as it receives signals from one of theinterconnected sensors or an external signal light switch.

7 The opus plus shallhave the facility to increase speed on a trickle and boost principle FAN SPECIFICATIONThe fans are acoustically lined with high density class "O" flame retardantacoustic insulation, giving extremely low noise levels and shall be complete withan integral filter, integral controls and facia mounted run and fail indication. Thebreakout noise level and power requirements shall be in accordance with theschedule and the manufacturer s details. The fans shall have low energy, high efficiency fan/motor assembly with sealedfor life PLUSThe unit shall be supplied complete with automatic fan changeover in the eventof failure, sensed via a "hall effect" airflow sensor, and auto duty share every 12hours of run time.

8 DUCT MOUNTED The unit shall incorporate a low profile single point mounting bracket,incorporating a pre-stressed synthetic anti vibration seal. The bracket shall enablethe unit to be mounted horizontally or vertically. The depth of the unit shall notbe greater than 260mm. The unit shall be constructed with one removable panelallowing full maintenance access. To facilitate the interconnection of branchducts the unit shall have 4x100 dia & 1x 125 dia knockouts on the suction sideof the unit (spigots provided) and 1 x 200 dia discharge shall be the OPUS100- (2) M or the OPUS150-M as manufactured MOUNTED All fan components are manufactured from ABS polymer and pre-coated finish shall be to have the option of an integrated PIR detector to switch the unit fromtrickle or off to full speed.

9 Air inlet grilles are fitted with foam filters to protectthe fan/motor assembly from airborne dust and contaminants. The unit shallhave a 125dia spigot to connect to ductwork or wall mounting kit. Surfacemounted LED indicators shall show the unit operational unit shall be supplied complete with automatic fan changeover in the eventof failure, sensed via a "hall effect" airflow sensor, and auto duty share every 12hours of run versions shall have the following functions integrally mounted within the fanunit on a purpose made PCB, all such components pre-wired and factory fittedby the manufacturer: Integral adjustable background ventilation control/set point (0 50%).

10 Integral adjustable trickle ventilation control/set point (50 100%). Integral adjustable run on timer. Integral S/L terminal for boost trigger from remote switch, light switch. Volt free failure/status indication. 3 years manufacturers unit shall be controlled by one of the following remote options: opus SPD Low voltage (12V) speed control, ON/OFF and speed controlbetween min and max settings. 230-PIR - (passive infra-red) movement detector (includes run-on-timer), 2-30 mins). 230-PIRNT - (passive infra-red) movement detector (without run-on-timer). HUMISEN - Humidity sensor.
