Hot Body Simulation Tests
A heat simulation test should be conducted.
The test is conducted by moving a “hot” (IR emitting) target into the view field of the Sensor
Head and observing / checking the consequential Alarm operation.
It is preferable that the “test target” is of sufficient size and temperature that the simulation
can be conducted at the plane of the monitored path (conveyor) such that the view field of
the Sensor can be validated. However, a smaller and cooler “test target” may be employed
so as to at least confirm basic operation of the sensor. It will be necessary with a “target” of
this nature to introduce it to the view field nearer to the Senor than the “monitored plane”.
When the 5610 detector is connected to fire panel via a conventional trigger circuit or
addressable loop detector interface, latched 5610 detections are normalized by Alarm
Reset operation at the fire panel. Similarly, when in relay mode, reset is conducted by
momentary supply interruption by an external push-button or other means.
Field of view test confirmation (which requires a number of alarm triggers) may more easily
be conducted when the unit’s covers are removed and the internal LEDs, Reset PB and
program SIL switch are still accessible. Refer to section 4.3.2.
If the location of the Sensor is classified as a “Hazardous Area” it will be necessary to make
special arrangements for this testing as the electrical / hot nature of the test simulation may
breach normal site regulations. It may even be that the test is precluded.
Refer to section 6.3 for information on “test targets”.
