such that it can only be seen when the housing is open/removed.
2.2.8.2
Remote Test, Infrared Emissions
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.
2.2.9
Microwave-Passive Infrared Dual Detection Motion Sensor
The dual detection motion sensor shall be a single unit combining a
detector which detects changes in the transmitted microwave signal and a
detector which detects changes in the ambient level of infrared emissions
caused by the movement of a standard intruder within the detection pattern.
The detection pattern shall be capable of covering a 6 by 9 m 20 by 30 feet
room. Upon detection of changes by either detector, a window of more than
3 seconds but less than 8 seconds shall be opened. If the other detector
detects a change during this window, the sensor shall transmit an alarm
signal to the alarm annunciation system. The passive infrared detector
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
detection pattern at a speed of 0.09 to 2.3 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 range of 8 to 14 microns. The microwave
detector shall detect a standard intruder moving within the detection
pattern at a speed of 0.09 to 2.3 m 0.3 to 7.5 feet per second. The
microwave detector shall comply with 47 CFR 15 Subpart F. The controls
shall not be accessible when the sensor housing is in place. The sensor
shall be configured to produce an alarm when both detectors sense a target.
2.2.9.1
Test Indicator
The sensor shall be equipped with an LED walk test indicator for both the
passive infrared detector and the microwave detector. 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 indicators or the test
indicators shall be located within the sensor such that it can only be seen
when the housing is open/removed.
2.2.9.2
Remote Test
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 each 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.
2.2.10
Photo-Electric Sensor
The photo-electric sensor shall detect an interruption of the light beam
