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 for a 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.

It is recommended that the accuracy of the burn period is confirmed using a stopwatch with the red  
indicator on the timer before conducting any live tests.  
Applicable code wire burn recommendations:  
BS6266:1992 recommends a burn time of 60 seconds for one metre wire lengths and 180  
seconds for 2 metres  
The NFPA 76 standard also recommends the same tests with an additional test with a burn time  
of 60s using 2 x 1m wires connected in parallel.

Operation  
a) Connect the IDE power cable (supplied) to the power input socket at the rear of the unit.  
b) Switch on using the rocker switch above the power input socket. This will illuminate red when in  
the “on” position. The green “Power” indicator on the timer will illuminate continuously.  
c) Set the timer to the required test period.  
d) Press the green push-button switch to the left of the timer. The red “Out” indicator will illuminate  
continuously and the green “Power” indicator will flash. 6V AC will be delivered to the two screw  
terminals on the front of the unit.  
e) At the end of the time period, the “Out” indicator goes out and the green ”Power” indicator will  
become steady.  
f) To repeat the process press the green push-button switch again, having set a different test period  
if required.  
g) On completion of the tests, switch the unit off using the rocker switch above the power input  
socket and remove the power cable.

Preparation and Connection of the Test Wire  
The test wire samples should be carefully measured and cut to the required length. The ends should  
be stripped at approximately 15mm using a suitable tool. If in doubt, please seek guidance from a  
qualified electrician. Only use the recommended test wire. Under no circumstances should  
test wires be shorter than 60cm or 2x1m in parallel. This is likely to age (or blow) the inlet fuse  
and may cause damage to the unit.  
Ensure that no power is connected to the Test Box. Insert the test wire between the output terminals  
and lay it on a supporting non-combustible platform. It is important to ensure that there are no cross  
overs of the wire. It may be helpful to first coil the wire using a pen or pencil as a temporary former  
and then lay it out. Alternatively, an arrangement to support the wire may be used with the precaution  
of a fire blanket positioned beneath the wire. If the equipment is in a high airflow area then it may be  
required to shield the wire from the airflow. At no time is it appropriate to open the Test Box.  
There are no user-serviceable parts inside.

Smoke Test  
Ensure that the local fire panel is isolated from the external fire reporting equipment and that any  
automatic extinguishing or suppressant systems are similarly isolated. Connect power to the Test  
Box and press the green push button switch. At this point, 6V AC is applied across the test wire, the  
red “Out” indicator will illuminate continuously and the green “Power” indicator will flash. The test wire  
will become hot and a quantity of smoke will be generated. The test wire becomes very hot during  
the test and will cause burns if in contact with skin. Care must be taken throughout this test  
process to protect both personnel and property from the hot wire.

The current to the wire is turned off automatically after the set period is complete. Smoke will have  
been generated and the time for it to be detected should be recorded to ensure that transport and  
alarm times are within the local regulatory requirements.
