Detectors must be tested after installation and periodic
maintenance. System Sensor 2400AT and 2400AIT Smoke
Detectors can be tested in the following five ways:

NOTE:

Before testing the detector, check for the presence
of the flashing LED. If it does not flash, power has
been lost (check the wiring), or it is defective (re-
turn for repair – refer to the Warranty).

A. Recessed Test Switch

1. Push and hold the recessed test switch with a 0.1 inch

maximum diameter tool, such as a pocket screw-
driver.

2. The LED on the detector should light within 5 sec-

onds. The p-horn should also sound.

B. Calibrated Test Card (R59-18-00)

1. Remove the detector cover by placing a small bladed

screwdriver in the side slot of the detector cover,
twisting it slightly until the cover can be turned coun-
terclockwise for removal.

2. Insert the NO ALARM end of the test card fully into

the test slot (see Figure 6) and slide it counterclock-
wise until it stops.

3. The detector should not alarm (wait at least 20

seconds).

4. Remove the test card by sliding it clockwise before re-

moving, then repeat with the ALARM end of the test
card.

5. The LED should latch on within 20 seconds, indicat-

ing alarm and annunciating the panel.

6. Replace the cover by gently rotating it clockwise until

it locks in place.

C. Test Module (System Sensor Model No. MOD400R)

The MOD400R is used with an analog or digital voltme-
ter to check the detector sensitivity as described in the
test module’s manual.

D. Aerosol Generator (Gemini 501)

Set the generator to represent 4%/Ft. to 5%/Ft. obscura-
tion as described in the aerosol generator manual. Using
the bowl shaped applicator, apply aerosol until the unit
alarms.

E. Direct Heat Method (Hair dryer of 1000-1500 watts)

Direct the heat toward the bimetallic collector. Hold the
heat source about 12 inches from the detector in order to
avoid damage to the plastic. When the heat rises to
greater than 135

°

F the detector will latch in alarm.

The detector will reset only after it has had sufficient time
to cool and the power source has been temporarily inter-
rupted. Both smoke and heat detection testing are recom-
mended for verifying system protection capability.

Detectors that fail these tests should be cleaned as de-
scribed under MAINTENANCE and retested. If the detec-
tors still fail these tests, they should be returned for repair.
Notify the proper authorities the system is back on line.

Maintenance

NOTE:

Before cleaning, notify the proper authorities that
the smoke detector system is undergoing mainte-
nance and, therefore, will be temporarily out of
service. Disable the system undergoing mainte-
nance to prevent unwanted alarms.

1. Remove the detector cover by placing a small-bladed

screwdriver in the side slot of the detector cover, twist-
ing it until the cover can be turned counterclockwise for
removal.

2. Vacuum the screen carefully without removing it. If fur-

ther cleaning is required, continue with step 3, other-
