1. WARRANTY

iSens only wants satisfied customers. The GLA is therefore supplied with a one-year
warranty from the date of purchase. The GLA may have the same lifetime as the energy
source, however, its lifetime may be reduced depending on outer environment, use,
alarm time, etc. A single alarm may completely deplete the energy source. See
technical data. This product is therefore a disposable consumable product with a 0–15-
year lifetime.
The warranty only covers material defects and malfunction related to manufacturing,
and only if the product has been used and maintained correctly. The warranty only
applies if the product has not been opened, attempted opened or repaired by the
customer. The warranty does not cover visible external / internal damage or energy
depletion. When using the warranty, the GLA must be submitted to the reseller in its
original packaging along with the original receipt. iSens' liability is limited to repairing
the product. Alternatively, iSens may replace the GLA with a new device (which may
be a newer model) or refund the original selling price.
iSens is not liable for any damages or losses arising from the GLA not functioning.
iSens is not liable for losses or injuries, material or other damages due to gas leaks, fire
or explosions. iSens' liability is limited to the purchase value of the product. The GLA
does in no way replace or fulfil recommended or mandatory safety measures for gas
leaks, fire or explosions in accordance with current laws and regulations. The GLA is
not type approved as a smoke detector. The GLA does not fulfil or replace any form of
insurance. Also read about automatic calibration in the safety chapter. The GLA only
provides an additional, optional contribution to increased safety.
In the event that the buyer disagrees with these warranty provisions, the GLA must be
returned before use in the original packaging, immediately and within the cancellation
period, which is normally up to 14 days for online purchases.

2. DESCRIPTION

The GLA contains a new Norwegian patented technology. The technology enables the
detection of several different gases by the same sensor. The sensor can therefore be
tested in a unique, simple and safe way using breathing air (carbon dioxide). Self-
Testing creates the greatest safety. The new technology has a self-purifying effect
enabling up to 3 times the lifetime of other alarms (optical and electrochemical). The
electronics are designed to achieve ultra-low energy consumption. The GLA will
therefore be able to function continuously for a total of 15 years without battery
change, power supply, adapters or chargers. This saves the environment and provides
safe alerts even in the event of a power failure. The GLA is ideal for the home, cabin,
camping, and boat.
Model: GLA - D
, Anaesthetic Gas

Version 2021-01
LPG gas (propane, butane) is heavy and stored in tanks. Gas may leak from a gas
fireplace, barbeque, cooker, gas stove, and other appliances. The gas can ignite when
the concentration exceeds the LEL (Lower Explosion Limit). The GLA alerts well
before this happens, already at 10–15 % of the LEL.
Domestic gas, or Household/Town gas, (methane, natural, biogas) is light and
distributed into homes in a pipe system. The gas may leak from pipes, hot water tank,
kitchen stove and heaters. The gas can ignite when the concentration exceeds the LEL
(Lower Explosion Limit). The GLA alerts well before this happens, already at 10–15 %
of the LEL.
Hydrogen is a light gas that is going to be used in many applications in the future. The
GLA alerts well before the gas concentration from a leakage reach LEL, already at 10–
15 % of the LEL.
Exhaust and smoke may come from engines, heaters, fireplaces, and fires. The GLA
alerts of carbon dioxide CO already at 5000 ppm. This corresponds to a normal
2
25 ppm of toxic carbon monoxide CO in exhaust from a diesel engine/heater. Less from
open heat and fire. The Norwegian exposure threshold limits are 5000 ppm of CO
25 ppm of CO in order to avoid impaired performance and health. The GLA alerts
when these limits are exceeded. The GLA is not type approved as a fire/smoke detector
for fire safety in private residences, but will provide additional safety, also in case of a
main power failure.
Carbon dioxide is produced by humans, animals, plants, fireplaces, gas stoves, candles,
and heaters. The GLA will alert if the Norwegian occupational exposure limit for
carbon dioxide is exceeded. This will give a good indication of the indoor air quality
and environment, especially in order to avoid impaired performance and other health
related consequences.
Anaesthetic gas has until recently been of the type chloroform and ether. Today,
odourless gas is used by various types of fluranes. The GLA is probably the only alarm
on the market alerting of both old and newer types of anaesthetic gases before they take
effect.

3. SAFETY

The safety regulations must be read before installing and using the product.
We recommend using at least two GLA sensors in order to obtain good operational
safety. With more sensors you achieve better coverage of areas where gases may
accumulate. This also increases protection against any sensor faults or depleted energy
sources significantly.
Important factors for the GLA to function normally:
The front switch must be ON.

 Correct placement (quiet, undisturbed location, low).
 Cleaning, removing dust with a dry cloth or brush.
Regular control of LED blink (daily)

 Regular testing (monthly).
Save energy (turn the alarm off immediately when testing).

Important factors that may cause the GLA not to function normally:
 The front switch is OFF.
Incorrect placement.

 Lack of monitoring and testing.
Covering, dust.

 Direct sunlight or heat radiation.
 Rapid or significant differences or changes in temperature.
Water, condensation and abnormally high air humidity.

 Solvents and other abnormal gases, smoke and fog.
Strong electrical or magnetic disturbances.

 Strong acoustic noise, outside audible range.
 Mechanical impact (vibration, shaking, shock, falling to the ground).
 Depleted energy source (alerts and testing deplete the energy source).
Information on False Alarm and significant/rapid temperature changes is found in
Chapter 4 and under Service at www.isens.no. Remember that odours from fuel gases,
exhaust and smoke may become uncomfortably strong before the alarm level is
reached.
If the GLA does not function normally, it must be turned off. Check the warranty.
Never attempt to open the box or repair the product yourself. This involves a high risk
of electrostatic short-circuiting and damage to the product.
The GLA has built-in automatic calibration. If the GLA has been exposed to a high gas
concentration (over time), it should be placed in a location without gas (outdoors) for a
few days to reset. If a gas leak is very small and lasts for a longer period of time, the
automatic calibration may cause the GLA to alert at a concentration slightly higher than
originally calibrated. Normally, a very small gas leak will be handled by natural
ventilation in the room. The GLA is designed to alert at sudden accidents where the
concentration rises relatively quickly from a normal level.
