within the sensor signal processor. The controls shall not be accessible
when the sensor signal processor housing is in place. The detection
pattern of a sensor element shall be circular with at least a 1.8 m 6 foot
radius on the protected structure.
2.2.7
Microwave Motion Sensor
The transmitted microwave motion sensor shall detect changes in a microwave
signal. Upon detecting a specific change, the sensor shall transmit an
alarm signal to the alarm annunciation system. The sensor shall detect a
standard intruder moving within the sensor's detection pattern at a speed
of 0.09 to 2.3 m 0.3 to 7.5 feet per second. The sensor shall comply with
47 CFR 15 Subpart F. The sensor's coverage pattern shall be as shown. The
sensitivity of the sensor shall be adjustable by controls within the
sensor. The controls shall not be accessible when the sensor housing is in
place. The sensor shall be adjustable to obtain the coverage shown.
2.2.7.1
Test Indicator, Microwave Signal
The microwave motion sensor shall be equipped with an LED walk test
indicator. The walk test indicator shall not be visible during normal
operations. When visible, the walk test indicator shall light when the
sensor detects an intruder. The sensor shall either be equipped with a
manual control, located within the sensor's housing, to enable/disable the
test indicator or the test indicator shall be located within the sensor
such that it can only be seen when the housing is open/removed.
2.2.7.2
Remote Test, Microwave Signal
A remote test capability shall be provided. The remote test hardware may
be integral to the sensor or a separate piece of equipment. The remote
test shall be initiated when commanded by the alarm annunciation system.
The remote test shall excite the sensing element and associated electronics
causing an alarm signal to be transmitted to the alarm annunciation system.
The sensor stimulation generated by the remote test hardware shall
simulate a standard intruder moving within the sensor's detection pattern.
2.2.8
Passive Infrared Motion Sensor
The passive infrared motion sensor shall detect changes in the ambient
level of infrared emissions caused by the movement of a standard intruder
within the sensor's field of view. Upon detecting such changes, the sensor
shall transmit an alarm signal to the alarm annunciation system. The
sensor shall detect a change in temperature of no more than 1.1 degrees C 2
degrees F, and shall detect a standard intruder traveling within the
sensor's detection pattern at a speed of 0.091 to 2.29 m 0.3 to 7.5 feet
per second across two adjacent segments of the field of view. Emissions
monitored by the sensor shall be in the 8 to 14 micron range. The sensor
shall be adjustable to obtain the coverage pattern shown. The sensor shall
be equipped with a temperature compensation circuit.
2.2.8.1
Test Indicator, Infrared Emissions
The passive infrared motion sensor shall be equipped with an LED walk test
indicator. The walk test indicator shall not be visible during normal
operations. When visible, the walk test indicator shall light when the
sensor detects an intruder. The sensor shall either be equipped with a
manual control, located within the sensor's housing, to enable/disable the
test indicator or the test indicator shall be located within the sensor
