WARNING

The sensor cannot detect smoke if the dust cover is in-
stalled.

2. Tamper-Resist Feature

The sensor bases include a tamper-resist feature that,
when it is enabled, prevents removal of the sensor with-
out the use of a tool. See the sensor base installation in-
struction manual for details on the use of this feature.

3. After all sensors have been installed, apply power to the

control unit.

4. Test the sensor by positioning a test magnet against the

sensor plastic directly opposite the test meter socket
(Figure 2). The alarm level should be recognized by the
panel and the LED controlled by communication com-
mand from the panel.

5. The reset of the sensor LED is controlled by communica-

tion command from the panel.

Testing
Before testing, notify the proper authorities that the smoke
sensor system is undergoing maintenance, and therefore
the system will be temporarily out of service. Disable the
zone or system undergoing maintenance to prevent un-
wanted alarms.

Sensors must be tested after installation and periodic main-
tenance. Test the sensor as follows:

A. Test Magnet (Model No. M02-04-00)

1. Place the magnet against the cover opposite the test

module socket to activate the test feature (see Figure 2).

2. The LED’s should latch on within 10 seconds, indicat-

ing alarm and annunciating the panel.

B. Test Tool (Model No. MOD400R)

Use the MOD400R with a DMM or Voltmeter to check
the sensor sensitivity as described in the MOD400R
manual.

NOTE: The MOD400R can be used to test the sensitivity of

only those sensors connected to control panels that
do NOT use drift compensation.

C. Aerosol Generator (Gemini 501) per NFPA 72

The field test tool is the GEMINI Model 501 aerosol gen-
erator. Set the generator to represent 4%/ft to 5%/ft ob-
scuration as described in the GEMINI 501 manual. Using
the bowl shaped applicator, apply aerosol until unit
alarms.

NOTE: This test only verifies smoke's ability to enter the

sensing chamber and initiate an alarm. It does
NOT test sensitivity.

Notify the proper authorities that the system is back on line.
