These pins are used to either program a fixed code (multiple devices with the same code) or to generate a
random code.
Range link.
The range link is a means of setting the level of Infra-red energy required to generate a pulse from the detector,
this in turn directly affects the range of the detector. The correct setting will depend on the size of the area to
cover.
- With the range link ‘ON’ the detector will detect to the full 12m x 12m.
- With the range link removed the detector will detect to approximately 8m x 8m.
The range link should always be set to the lowest setting which will still provide good coverage.
Pulse Count link.
At times it may be unavoidable to install the detector in a difficult environment. Pulse count is a means of
adjusting the number of pulses received (therefore the number of steps) before an alarm is generated.
- In a normal stable environment the link should be ‘ON’. 1 to 2 pulses will cause an alarm.
- In doubtful environments remove the link. 3 to 4 pulses will cause an alarm.
6.3.1 Radio Reed Switch
The Ness radio reed switch is a multipurpose radio device. It has an internal reed switch and has the provision
for an external reed switch. It can also function as a radio vibration analyser if a Nessensor (VIB100) is
connected to the external device input.
A 9 volt lithium battery powers the reed switch and should last approximately 3 years (@25 activation’s per
day).
Terminals and Link Settings:
Two way terminal block (TB1)
The terminal block is used to connect a normally closed reed switch or a Nessensor (VIB100). The cable
length to the external switch should be kept to a minimum and no longer than 40 cm.
I\B\E Pins:
Link in ‘I-B’ position.
Only the internal reed switch controls the transmitter. External devices are disabled.
I\B\E Link REMOVED.
Both the internal reed switch and the external device are connected in series with the transmitter.
Link in ‘E-B’ position
Only the External device controls the transmitter. The internal reed switch is disabled.
Program link.
Program mode should only be needed if a new 16 bit code (random or fixed) needs to be entered. See the setup
\ testing section on page ?? to program a fixed code into a reed switch.
1\0\R Pins.
These pins are used to either program a fixed code (multiple devices with the same code) or to generate a
random code.
Radio Enable link.
Having the link ‘ON’ will allow the radio transmitter to operate. Taking the link ‘OFF’ will disable the
transmitter ( could be handy when programming multiple detectors into the main unit). The LED will indicate
