NB These dust covers do not provide adequate protection against quantities of dust generated by building work sanding etc Therefore detectors should not be installed until this type of work has been completed TESTING All detectors must be tested following installation or routine service and maintenance Authorised personnel must be informed that the fire system will be temporarily out of service before commencing testing When all tests are complete restore panel to normal operation and notify authorised personnel that the system is operational Smoke Detector Settiings Subject the detector to be tested to a controlled amount of an approved synthetic smoke aerosol via a smoke detector test pole Suitable products are available for example from No Climb Products Ltd Check that the red LED on the detector lights in alarm within 30 seconds Ensure that the control panel activates into alarm Either reset the detector from the control panel or allow the detector to automatically reset once clear of smoke if this option has been selected This procedure will test the smoke sensing circuitry of the Opto Heat Detector Heat Detector Settings Using a heat gun or hair dryer capable of generating temperatures of up to 95 C direct the heat source towards the heat sensing elements visible through the side of the outer cover from a distance of 15 to 30cm Care should be taken not to allow the plastic surface temperature to e

4. reached the limit of its contamination compensating ability Choosing the right detector The M12 can be configured using the four position switch located at the back of the detector as Optical smoke detector SW3 Off SW4 Off this detector is suitable for most applications giving the fastest response to slow burning or smouldering fires which give rise to large visible smoke particle Opto heat detector SW3 On SW4 Off this will respond better to fast clean burning fires yet maintain the advantage of optical detectors when detecting smouldering fires The thermal enhancement of this detector allows a higher alarm threshold which provides a greater rejection of false alarms The detector will also give an alarm at temperatures above 60 C Rate of Rise heat detector SW3 Off SW4 On this detector will detector a rapid increase in temperature or temperatures above 60 C and should be used in environments where the ambient conditions might cause false alarms if smoke detection were to be used for example where there is a high level of dust fumes steam or smoke under normal conditions Fixed 77 C heat detector SW3 On SW4 On this detector will detect temperatures above 77 C and should be used in environments where the ambient conditions might cause false alarms if smoke detection were to be used for example where there is a high level of dust fumes steam or smoke under normal conditions in the Optical and Opto
5. Heat mode the detector automatically compensates for gradual increase in the scatter signal due to contamination e g dust build up If excessive dust occurs the yellow LED will show continuously In these circumstances remove the detector head and vacuum around the outside of the mesh If this fails to solve the problem the detector should be replaced The yellow LED will be lit continuous if the detector sensor signal begins to reduce below its normal level chamber monitoring Detector Setting Opto Opto Heat Rate of Rise 77 C Fixed LED Off Normal Mode Red LED Puts ing Normal Auto Reset Laiching Rela Utilising Locking Tab The mounting base includes an optional feature to prevent the removal of the detector without the use of a tool 4 Remove the standard fit retaining clip 2 Insert the locking clip which is located at the centre of the base as shown Mount the detector onto the base as described in Detector Installation see over and rotate fully clockwise until it finally clicks The detector is now locked into position Remove by utilising a suitable tool eg a thin screwdriver into the hole in the detector cover Gently push the tool into the detector and rotate anti clockwise Doc Ref PINSTMY2 iss B Det Reset Ve yje flan SX i 3 ov 142V Fire Zone
