CONFIGURING THE GEMC-BSLC-PIR
Low Temperature Alarm for Heating System Monitoring
(a Patented Feature
)
The GEMC-BSLC-PIR has the ability to activate a Low
Temperature Output in the case of the ambient temperature
falling below 40°F.
This feature functions exactly the same
as if you had purchased a separate temperature switch
.To
enable this feature, connect a jumper across pins LT and
wire the Trouble Output (terminal 5) into the positive terminal
of a zone programmed for 24 Hour protection. This output
signal will remain active for as long as the temperature
remains below 40°F, when the temperature rises several
degrees above this the output will reset .
High Temperature Alarm for Cooling System Monitoring
(a Patented Feature)
The GEMC-BSLC-PIR has the ability to activate a High
Temperature Output in the case of the ambient temperature
rises above 90°F.
This feature functions exactly the same
as if you had purchased a separate temperature switch
. To
enable this feature, connect a jumper across pins HT and
wire the Trouble Output (terminal 5) into the positive terminal
of a zone programmed for 24 Hour protection. This output
signal will remain active for as long as the temperature
remains above 90°F,when the temperature falls several
degrees below this the output will reset.
Note:
If the unit is in a high or low temperature condition, the
LED will glow dimly instead of being completely turned off ,
this can be used to test the units temperature monitoring
feature. If it is desired to test the temperature monitoring
feature, it will be necessary to either trip the unit or wait
several minutes for the unit to measure the temperature,
because the room temperature is measured every 10
minutes or each time an alarm is tripped. You will need
freeze spray or a freezer to test low temperature or to test
high temperature a hairdryer will do. Heat or cool the
temperature sensor (refer to Circuit Board Detail), then trip
the unit, assuming it hasn't done that already and let it settle
and observe the LED for a dim glow.
LED Disable Jumper
To prevent the walk test LED from turning on, remove the
jumper from the pins labeled LED DISABLE. Removing this
jumper will not affect the flashing of the LED on self test
failure or the dim glow during a high/low temperature
condition.
Sensitivity Setting (SEN Jumper)
The unit is shipped with no jumper in this position. This is
the normal sensitivity mode and is recommended for most
installations whose coverage area does not exceed 30' x
35'. Coverage out to 50' x 50' is possible in this mode, but
the intruder will have to cover a larger distance before
detection. To have faster catch performance this jumper
must be installed.
Note:
Advanced signal processing will be
defeated in this high sensitivity mode. DO NOT INSTALL
THIS JUMPER IF PETS OR RODENTS ARE PRESENT. If
LENS818 (Barrier Lens) or LENS840 (Long Range Lens) is
used, it is recommended that the SEN jumper be installed.
Vertical Aiming
(refer to lens coverage pattern)
The height scale that is on the board is intended to make
vertical aiming quick and easy. If the board is set to the
same number as the height the unit is mounted at, the unit
will be aimed for maximum coverage. However, if the unit is
used for less then the maximum range, move the board up
(towards 12 ft.) and walk test the unit.
Note:
If the wall upon
which the unit is mounted is not vertical, move the board up
or down and walk test the unit. If using the Long range or
Barrier Lens, set the board to 12 feet on the height scale as
a starting point as aiming accuracy for long range lenses
can greatly affect performance.
Horizontal Aiming
(refer to lens coverage pattern)
The lens may be moved left to right within its holder to help
avoid problem areas. However, the most effective solution
for a possible problem area is to block the zone, by applying
a piece of lens foil (supplied) to the inside segment of the
lens representing that zone.
Installations with Pets
The GEMC-BSLC-PIR will provide good immunity to small
pets in most applications. The pet or pets should be small
(less than 20 lbs.). Several small cats are acceptable. If
you have three or more large ones, we recommend that the
NAPCO GEMC-BSLC-DT "dual technology" sensor be
used. Mount the unit as high as possible. If the unit is
above a chair or other piece of furniture that the pet may
climb onto, mask the look down beam. Make certain the
sensitivity (SEN) jumper is off (normal sensitivity). If a stair
case is in the field of view and closer than 20ft. from the unit,
it may be necessary to mask that beam.
REPLACING THE LENS
The lens is mounted behind a Lens Support insert that fits
inside the front cover. To install one of the accessory
lenses, proceed as follows
:
1. Carefully lift the lens cover from the housing.
2. Remove the bug shield, which will expose the lens
support assembly.
3. While pushing the lens in at the top, with fingers
straddling the LED jewel, press down at the top of the
Lens Support as shown until the support clears the three
top retainers. Be careful not to dislodge the look down-
lens window.
4. Push the Lens Support up until it clears the three bottom
retainers and remove the assembly.
5. Slide out the lens.
6. Install the replacement lens with the grooved side in and
the with the lens not in the up side down position. All
lenses are marked with with the word top stamped on the
Replacing the lens
NOTE:
Remove
the bug shield
before removing
the lens.
