Option units for ET-999
You can add extra units to ET-999: ET-67 for the hard-of-hearing, ET-68 extra
anaesthetic/gas sensor, or ET-69 CO (Carbon Monoxide) gas sensor.
ET-67 is the extra sound and light alarm unit which in addition to the sound
alarm comes with a white LED light flash alarm to warn the hard-of-
hearing. The white flash is also known to discourage a possible intruder.
ET-67 should be mounted over the bed directly over the sleeping person.
ET-68 is equipped with the same type of gas sensor element as ET-999. ET-
68 must also be placed low (max. 50 cm over the floor). ET-68 is designed
to be placed in the children sleeping area or close to a unit that is running
on gas (kitchen area).
ET-69 is the CO (Carbon Monoxide) gas sensor. It must be mounted under
the ceiling because CO gas is lighter than air.
The ET-69 has a calibration time of 5 minutes, so the first 5 minutes the
orange LED will be on. After 5 minutes only be the green LED is on. If CO
gas is detected, the alarm will sound and the RED LED light will light up.
ET-69 is testing for CO gas at intervals: 1 minute testing (green LED on), 1½
minute resting (green LED flashing)
The ET-69 uses less power in the resting mode therefore the two figures in
the power consumption.
When an option unit (ET-67, ET-68, or ET-69) is connected to ET-999, you
must switch off the ET-999 before you add the new unit. After connecting
the new unit you switch on ET-999 allowing the microprocessor to identify
the new unit that has been connected to ET-999.
Warning!
•
ET-999 must only be connected to a true 12VDC voltage “direct
voltage”
•
The option unit(s) (ET-67, ET-68 or ET-69) must always be connected
to the ET-999 in the designated sockets of ET-999. If not connected
correctly, you will damage not only ET-999 but also the option
unit(s).
ET-999
Anaesthetic/gas alarm with voltage guard
Instructions & technical manual
ET-999 is designed specially for protection of caravans, auto campers, and
boats to detect and warn against an escape of anaesthetic (narcotic) gasses
and other known gasses like propane, butane, methane, ethanol, LPG as well
as other anaesthetic or combustible gasses. The gas alarm does not react to
smoke, CO and CO
2
gas.
CO gas sensor (ET-69) can be added to ET-999
ET-999 is extremely sensitive to above gasses. Also it is very stable and requires
only a minimum of maintenance and no calibration.
ET-999 has a built-in voltage guard alarm that activates if the power to ET-999
is cut and warns by voltage disruption.
The voltage guard alarm also activates if the DC voltage is too low or if the
voltage of the 9 volt battery is below 7,0 volt.
The gas sensor in ET-999 and ET-68 is a high quality element that is normally
used only in professional gas detectors. This gas sensor was chosen to ensure
the very best safety and highest reliability with a minimum of service and no
calibration.
