1.0 - INTRODUCTORY NOTE
Dear Customer,
Thank you for purchasing a Gemini product.
The present manual has been written to help you understand and use the
narcotic and LPG detector 911,specificallydesignedforrecreationalvehicles.
Read the supplied instructions thoroughly and keep them handy.
USER MANUAL
Should gas be sprayed into your vehicle, the 911 sensor is able to detect it and
set off an alarm in a few seconds, long before the gas can have any effect on
the occupants.
The 911 detector also activates the output relay which actuates other devices
(ex. cabin lights, vehicle horn, etc.) to discourage anyone trying to break in
your motorhome.
N.B. In compliance with European standard En50194, the detector can
signal the presence of explosive gas (LP), when its concentration is
higher than 10% of the LEL (Lower Explosive Limit, the minimum
concentration which can cause an explosion).
2.0 - OPERATION DESCRIPTION
We recommend operating the detector
bedtime
If the detector is switched on uselessly (ex. While driving, when the vehicle is
stowed away,etc.),thedetectingprobemayexhaust.
When power is applied to the detector, it will go through a warm-up period and
will be inhibited for at least 3 minutes; during this so-called “warm-up” phase,
the yellow LED will blink.
This phase is necessary to allow the sensible element to warm-up andstabilize
itself in order to ensure proper operation conditions.
After this time delay,theyellowLEDturnsoff and the detector is ready to work.

2.1 - STARTING AND WARMING UP

PAGE 02
!
The 911 detector does not detect Carbon Monoxide (CO).
USER MANUAL - PAGE 03

3.0 - ALARM SIGNALS
3.1 - NARCOTIC GAS
Thedetector continuously monitors the narcotic gas concentration level in the
cabin by carrying out calculations to self-adapt to the different air quality
conditions (use in urban areas is different from use in country places).
If a sudden increase in the concentration level is detected due to narcotic
gases being sprayed in the vehicle, the detector immediately activates the
siren and the output relay.
The alarm state remains ON until the conditions which have triggered it are
present.
To deactivatethealarm,simplydisconnectit.
3.2 - EXPLOSIVE GAS LPG
The detector continously monitors the LPG concentration level in the cabin; if
its concentration exceeds 10% of theLEL(Lower Explosive Limit), the detector
immediately activates the siren and the output relay.
The alarm state stays on until the conditions which have generated it are
present.
Important Note:
the installation instructions (see chap. 13.0).
for LPG detection, the sensor must be installed according to
4.0 - POWER SUPPLY
The detector can operate both at 12V or 24V, by setting the voltage switch Sl1.
!
The 911 is equipped with a relay that actuates other devices (ex. cabin
lights or vehicle horn or any other alarm device).
The relay supplies the contacts NC - C - NO on the terminal block M1 (see
connection example in par.11).
By default, the detector is set at 12Volt.
5.0 - SELF-DIAGNOSIS
The detector is provided with an acurate and reliable self-diagnosis system
which continuously checks its performance and efficiency; any failure or the
exhaustion of the probe, afteralifecycleof more than 11,000hrs, is signaled by
the yellow LED turning ON and by a warning alert signal.
When the probe is exhausted, contact an authorized dealer for
!
replacement or reconditionning of the detector.
6.0 - SENSITIVITY LEVEL SELECTION
By default, the detector is set to “normal” sensitivity; in case of particular
environmental conditions, the sensitivity can be set to “low” by opening or
interrupting jumper P1.
Jumper P1: closed = normal sensitivity
Jumper P1: opened = low sensitivity
Changing the sensitivity setting will not modify the alarm threshold
!
level for explosive gas LPG, 10% of the LEL.
7.0 - IMPORTANT CAUTIONS
!
Use only a damp cloth to clean the detector; do not use thinners (alcohol,
detergents, etc.) which could irreparably damage the detector.
!
Alcohol based cleaning agents, perfumes, deodorants, varnish thinner
fumes, insecticides and other sprays can interfere with the correct
operation of the sensor and create improper alarms and/or alter the device
sensitivity.
Silicone vapors in the cabin can deteriorate the detector sensing element.

9.0 - WARRANTY CONDITIONS
This product isguaranteed to be free from defectsin workmanship for a period
of 24 months from the date of installation reported on the present warranty, in
compliance with the1999/44/CE Warranty Directive (L.D. N° 24 02/02/2002).
Please fill-in entirely the guarantee certificate included in this manual and DO
NOT REMOVE the guarantee label affixed to the device.
The warranty will become void if labels are missing or torn, if the installation
certificate is not fully compiled or if the enclosed sale document is missing.
The warranty is valid exclusively at authorized Gemini Technologies centers.
The manufacturer declines any responsability for eventual malfunctions of the
detector or any damage to the vehicle electrical system due to improper
installation, use or tampering.
INSTALLER MANUAL
10.0 - INSTALLATION
The 911detectorisintendedforapermanentinstallation.
The device must be positioned at about 20-40 cm from the vehicle cabin floor
to be protected.
The detector must be installed at least 1-1,5m away from any air supply
register; if there is an air intake vent, install the detector near it.
10.1 -FITTING OF DETECTOR
!
Remove the detector cover by prying lightly with a screwdriver inserted in
the release slot on the right side of the casing.
!
The two screw holes (FF) can be used to mount the detector to a wall or
onto a base(fig.1); the electronic card must firstbe removed by unscrewing
the screw on the bottom right corner.(seepar. ).
10.2 - ELECTRICAL CONNECTIONS
!
The pre-drilled holes (FC) are used to run the power wiring (see par. ).
!
Connect the wires that supply 12 or 24V to the terminal block M2 (see par.
12)
; depress the supply terminal block to introduce the cables which must
have a section comprised between 0,5 and 1,5 mm².
!
Remove 9mm of sleeve from the cable before inserting it in the terminal
block; release the push-button and pull on the cable to make sure it is well
secured.
!
The auxiliary devices conductors intended to manage the alarm must be
connected to terminalblockM1; the maximum rating of the relaycontactsis
2A at 28Vdc (refer to par. 13). To actuate devices having a higher
absorption rate, an auxiliary relay must be provided.

The maximum relay contact capacity is 2A at 28Vdc; to actuate devices having
a higher absorption rate, an auxiliary relay must be provided.
For safety reasons, always insert a protection fuse (3-4A max.)
!
between the device to be managed and the detector contacts.
