ACCESS MENUS

Dust covers provide limited protection against airborne
dust particles during shipping and must be removed before
the sensors can sense smoke. Remove sensors prior to
heavy remodeling or construction. Be sure to remove the
dust covers from any sensors left in place during construc-
tion prior to returning the system to service
Testing
Before testing, notify the proper authorities that the system
is undergoing maintenance, and will temporarily be out of
service. Disable the system to prevent unwanted alarms.
All sensors must be tested after installation and periodical-
ly thereafter. Testing methods must satisfy the Authority
Having Jurisdiction (AHJ). Sensors offer maximum per-
formance when tested and maintained in compliance with
NFPA 72.
IMPORTANT: If testing is done with non-intrinsically safe
methods, it should be conducted outside the hazardous
area.
The sensor can be tested in the following ways:
A. Functional: Magnet Test (P/N M02-04-01)
This sensor can be functionally tested with a test mag-
net. The test magnet electronically simulates smoke in
the sensing chamber, testing the sensor electronics and
connections to the control panel.
1. Hold the test magnet in the magnet test area as shown
in Figure 2.
2. The sensor should alarm the panel.
Two LEDs on the sensor are controlled by the panel to
indicate sensor status. Coded signals, transmitted
from the panel, can cause the LEDs to blink, latch on,
or latch off. Refer to the control panel technical doc-
umentation for sensor LED status operation and
expected delay to alarm.
B. Smoke Entry: Aerosol Generator
Aerosol generations for smoke entry testing are available
from a number of third party manufacturers (e. g.,
Gemini Scientific). Following the manufacturer's instruc-
tions, apply aerosol until the panel alarms.
A sensor that fails any of these tests should be cleaned as
described under CLEANING, and retested. If the
sensor fails after cleaning, it must be replaced and returned
for repair.
When testing is complete, restore the system to normal
operation and notify the proper authorities that the
system is back in operation.
