A g Kidde Fire Protection HOT WIRE TEST BOX USER GUIDE TMO0098 WARNING Please read this guide fully before attempting to operate the unit 1 0 Introduction This Guide describes the use of the Kidde Fire Protection Hot Wire Test Box part number 1 53836 K237 to test aspirating smoke detection systems The unit provides 6V AC output from 220 240V AC mains supply High current at low voltage is passed through a cable in order to heat it which causes its insulation to burn giving off smoke A timer is incorporated to provide a selectable burn period of up to 3 minutes The timer also helps to prevent the unit being inadvertently left on for an extended period The unit must never be left on unattended The unit must be operated for no more than three 3 minutes continuously and must be left off immediately after operating fora period of at least six 6 minutes to allow it to cool The unit is protected against over temperatures by a thermal switch Once tripped the thermal switch will not allow operation for an extended period up to an hour regardless of power being present or not The thermal switch cannot be by passed or reset manually Hot Wire Test Unit TMO0098 Page 1 of 4 Issue 1 00 2 0 Preparation and Precautions When performing a hot wire test ensure that all local standards practices and regulations are understood and have been adhered to where applicable Also ensure that the detection equipment being
