2.2.2 Magnetic Oi

The detector also incorporates a magnetic oi feature that provides the

same calibrated test as the automatic oi, and in addition actuates an

alarm to verify output operation for preventive maintenance

requirements. This feature can be performed at any time and

eliminates the need for testing with an external test lamp.

CAUTION: These tests require disabling of all extinguishing devices

to avoid release resulting from a successful test.

Perform the magnetic oi test by placing a magnet by the marked

location (mag oi) on the outside of the detector. This test activates the

calibrated IR emitters. If the resulting signals meet the test criteria,

indicating that greater than half of the detection range remains, an

alarm message is sent to the panel and the indicating LED changes to

red. This condition remains until the magnet is removed.

If less than half of the detection range remains, no alarm is produced

and a fault is generated.

The AutroSafe IFG panel has to be reset after the test is completed.

2.3 Automatic Alarm Test

The X33AF PL performs an automatic alarm-path test every 24 hours.

This test includes the functionalities of the magnetic oi test, and is also

making sure that the alarm is transmitted to the panel. If this test is

successful, no indication will be given on the panel. However, if the

test fails, a fault message is generated on the AutroSafe IFG panel.

2.4 Communication

The X33AF PL has built-in PowerLoop technology which makes the

detector capable of being powered by and communicating with

AutroSafe Integrated Fire and Gas panels (IFG) on the same pair of

wire, saving cable cost and weight.

2.5 Data Logging

Data logging capability is also provided. Status conditions such as

normal, power down, general and oi faults, pre-alarm, fire alarm, time

and temperature are recorded. Each event is time and date stamped,

along with the temperature and input voltage. Event data is stored in

non-volatile memory when the event becomes active, and again when

the status changes. Data from the log can only be extracted at the

factory.
