shall be weatherproof. The housings of recess mounted switches and magnets
shall be made of nonferrous metal or plastic.
2.2.1.2 Remote Test
Provide a remote test capability. The remote test shall be initiated when
commanded by the alarm annunciation system. The remote test shall activate
the sensor's switch mechanism causing an alarm signal to be transmitted to
the alarm annunciation system. The remote test shall simulate the movement
of the actuating magnet relative to the switch subassembly.
2.2.2 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 2 degrees F,
and shall detect a standard intruder traveling within the sensor's
detection pattern at a speed of 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.
2.2.2.1 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
such that it can only be seen when the housing is open/removed.
2.2.2.2 Remote Test, Infrared Emissions
Provide a remote test capability. 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.
2.3 FIELD PROCESSING HARDWARE
2.3.1 Alarm Annunciation Local Processor
The alarm annunciation local processor shall respond to interrogations from
the field device network, recognize and store alarm status inputs until
they are transmitted to the central station and change outputs based on
commands received from the central station. The local processor shall also
automatically restore communication within 10 seconds after an interruption
with the field device network and provide dc line supervision on each of
its alarm inputs.
a. Inputs. Local processor inputs shall monitor dry contacts for change
of state that reflect alarm conditions. The local processor shall have
