•
For analog and analog-HART model detectors, the signal output in alarm (20mA), can be
measured using a current measuring device placed in the analog loop or across the meter test
jacks inside the junction box.
•
For relay model detectors, changes in fire alarm relay status may be monitored at the detector
relay terminals or panel.
•
For digital model detectors, digital responses may be monitored at a PLC/panel.
• After successful fire simulation, release the test lamp pushbutton and discontinue external
system bypass (return external system to normal operating mode).

Follow the steps below to ensure accurate testing and fire simulation using the test lamp.
Important
When completing a fire simulation, ensure that the external system is in bypass or erroneous
activation of the safety system may occur.
•
Point the test lamp at the detector window, no greater than 20 feet (6.06 meters) from the
detector, as shown in Figure 3-1 , then press and hold the test lamp pushbutton.
• To simulate a fire condition, press and hold the test lamp pushbutton while directing the IR laser
(red dot) at the detector’s IR sensor as shown in Figure 3-3 . After the detector time delay has
elapsed, the detectors red LED will flash to indicate a fire condition. Refer to the detector
manual (MAN-0015 or MAN-0075) for time delay settings.
