6. Changing the battery
When the battery is weak, the PYR-2011A will send a signal to the
panel, including LED signals (refer to Signaling Table) indicating a
weak battery. Although the detector can continue working for an
additional amount of time, it is prudent that the battery be
replaced as soon as possible.
To change the internal battery:
1) Follow the directions in the section Opening the
PYR-2011A.
2) Remove the PCB unit from the housing by pressing down
on the retaining latches and tilting the PCB out from the
bottom.
3) Remove the battery and replace with a 3vdc, 1300 mAh
model CR123A only. Pay attention to the polarity of the
battery when inserting into the holder.
CAUTION: Danger of explosion if battery is replaced incorrectly.
Replace only with 3V Lithium GPCR123A or equivalent. Dispose of
used batteries according to the manufacturer’s instructions.
4) Replace the PCB cover of the PYR-2011A and the locking
screw.
7. Jumper and Tamper Setting
PYR-2011A has two jumpers, JP1 and JP2 and reed switch S3 (test
mode) operated by placing a magnet over it.
7.1 Sensitive Level Jumper (JP2)
To prevent false alarms in harsh environments, three sensitivity
modes were designated:
Low for harsh environments, jumper on pins 2 and 3
Medium for normal usage, jumper off
High for high sensitivity when there is little chance of false
alarms, jumper on pins 1 and 2
7.2 APS Auto Power Save Mode (JP1)
To save power, the PYR-2011A goes into sleep mode after sending
an alarm. The time the device will be latent is set by the radio
mode jumper, JP1.
Normal (always 2 minutes between alarms) no jumper.
Dynamic (2 minutes retriggered between alarms) jumper on.
When the dynamic mode is set, an alarm event will be sent only if
there were 2 minutes of silence prior to the current alarm. This
setting is useful for places with a high level of traffic, such as
factories, shops, etc.
7.3 Back Tamper (R11)
NOTE: When using the corner mount or bracket the back tamper is
not applicable.
The PYR-2011A has both front and back tamper detection. Front
tamper detection is on by default and it is activated when the
cover is opened cannot be changed. The back tamper detection
is activated when the detector is pulled off the ceiling and is
disabled by default, to enable the back tamper detection cut the
back tamper wire - R11 - which is marked on the PCB as a scissor
print.
7.4 Test Mode Switch (S3)
The detector utilizes a contactless switch (enabling easy testing
without opening the case): Walk testPlace a magnet over the
right side of the lens for 1 second only; PIR functionality will be
evaluated, for a 1 minute period. (After self check at power up the
walk test is automatic enable for 2 minutes.)
Radio test Place a magnet over the right side of the lens for more
than 3 seconds; the red indicator illuminates. 10 Alarms events are
transmitted every 4 seconds. This test is to insure clear RF passes
between the detector and the control panel.
In all modes the LED will remain activate at all trouble
announcements. Refer also to panel manual for RF testing details.
8. Testing the Detector
The PYR-2011A PIR has a built-in walk test function where the LED of
the PIR is enabled. This test is used to check the detection of the
PIR and the coverage pattern.
To perform a walk test:
1) Ensure all of the settings in the PIR are adjusted as
necessary for the location according to the installation
instructions above.
2) Insert battery in the closed case as described above. The
LED flashes on for 2 seconds and off for 2 seconds for a
period of 1 minute. Then the LED turns off. At this point a
walk test can be performed. As default, perform a walk
test of 2 minute at the end of the self test. If more than 2
minute goes past, refer to paragraph 3.
3) Place a magnet over the right side of the lens for 1 second
only.
4) With the LED enabled the LED flashes every time the
detector detects motion. There is a two second wait
period before the next detection.
5) It is recommended that the installer test the detection by
going over the protected area and seeing that the
detection pattern is good.
6) After 1 minute, the LED goes off. If a new walk test is
needed, go again to paragraph 3.
9. Signaling Table
The LED on the front of the PYR-2011A is used to send several
signals to the user. The following table describes the signals for
different activities:
Activity
LED Signal
Warm-Up The LED flashes on for 2 seconds and off for 2
seconds for a period of 1 minute. If the warm-up is
successful, the LED stops flashing and the system is
ready for detection.
Detect Condition
The LED flashes on for 2 seconds and then turns off.
Activity
LED Signal
PIR Problem The LED flashes on for 1 second and then off for 1
second. A PIR check is conducted every 3 hours.
Temperature Problem The LED flashes on in short bursts.
