12 Intelligent Products—2251J Plug-In Low Profile Intelligent Photoelectronic Smoke Detector
Functional: Magnet Test (M02-04-01)
This detector can be functionally tested with a test magnet. The test
magnet electronically simulates smoke in the sensing chamber, and tests
the detector electronics and connections to the control panel.
1.
Hold the test magnet in the magnet test area (Figure 4).
2.
Both LEDs should latch on within 30 seconds indicating an alarm.
3.
The control panel should register an alarm from the detector.

Sensitivity: Test Module (MOD400R or MOD400)
A sensitivity test module socket (Figure 4) is provided for checking the
detector’s sensitivity with the MOD400R or MOD400 test module
(supplied separately). The test module is used with a digital or analog
voltmeter to check the detector sensitivity. An acceptable voltage range is
stamped on the back of the detector. Test the detector as described in the
test module manual.
If the detector’s sensitivity limits or the MOD400 limits do not appear on
the back of the detector, the MOD400 is not suitable for field sensitivity
testing of that unit.
