1. 4 Faults or Malfunctions The FCC is modular in construction so the correction of mechanical or electronic faults usually entails the replacement or adjustment of the appropriate sub assembly Only qualified personnel should attempt to repair the instrument otherwise it is recommended that a faulty module be returned to the distributor or manufacturer for repair The heater temperature is factory set but can be adjusted by authorized service personnel The adjustment is accessed through an opening beside the heater door This opening is fastened with security screws to hinder unauthorized access A thermal switch protects the heater This switch trips at approximately 200 C and auto resets at approximately 160 C It is accessed by removing the shroud that is secured to the hotplate with security screws This procedure should only be undertaken by authorized service personnel A repair manual for suitably qualified personnel can be obtained from Carter Scott Design 4 thermal fuse 228 C fitted up to S No 1080 Forensic Cyanoacrylate Cabinet FCC171 C amp D User s Guide Version 2 4 Appendix A Technical Specifications Operational phases Power supply Displays Internal air circulation Additional safety features FCC171D Externally ducted exhaust FCC171C Integral ductless fume purging with filter Cabinet Internal dimensions External dimensions weight Shipping crate dimensions weight Accessory St2. so the FCC sits securely 12

CC will not function if the cabinet door is left ajar The control also monitors for system malfunction such as a jammed vent flap in which case the operation is frozen and the user informed via the interactive display Technical specifications are listed in Appendix A 1 2 Safety Notes Cyanoacrylate superglue is a strong irritant to eyes and the respiratory tract and it bonds to skin The FCC has been designed to reduce as much as is practicable the possibility of any accidental contact However if superglue does splash into the eyes they must be immediately flooded with copious quantities of water and medical attention sought If superglue bonds to the skin it may be removed with acetone The heater can become very hot so do not attempt to access the heater until the Exhaust Purge phase is complete 1 3 Using the Cyanoacrylate Fuming Process to Develop Latent Fingerprints The cyanoacrylate vapour produced during the fuming process reacts with greasy or moist latent fingerprint ridges to form a hard white polymer The rate of cyanoacrylate development depends on the type and age of fingerprints environmental exposure of the exhibit contamination and the nature of the surface bearing the latent fingerprints The polymer will also appear on the background surface as well although in most cases at a much slower rate Consequently the cyanoacrylate development should be monitored to obtain good ridge detail and to avoid overdev
5. OF THE FCC 1 Introduction This User s Guide outlines the features and operation of the FCC171 series of Forensic Cyanoacrylate Cabinet referred to in this Guide as the FCC The FCC171 C model has integral ductless fume purging The FCC171 D model has ducted fume extraction and must be connected to an external exhaust facility Since the late 1970s it has been known that cyanoacrylate ester superglue fumes can be used for the development of latent fingerprints on non porous surfaces The FCC provides a secure cabinet to safely control and accelerate this technique 1 1 Description of the FCC The FCC comprises a sealed aluminium cabinet with glass sides and glass door The cabinet has two exhibit shelves and an overhead lamp A control box sits above the cabinet and a heater unit sits below The operation of the FCC is under microprocessor control with an interactive display giving clear user prompts The heater unit operates at low voltage and is under closed loop temperature control to provide optimum cyanoacrylate evaporation The heater temperature is factory set to be always safely less than the temperature approximately 210 C at which cyanide fumes may develop There are separate low voltage fans for fume circulation gentle and for fume extraction high flow Various safety interlocks are monitored by the microprocessor so as to reduce the possibility of inadvertent exposure of the user to irritating fumes For example the F
