Honeywell Midas S2 User Manual page 52

General Notes:
1 Midas S2 detectors are not ETL approved for monitoring in or sampling from classified areas
above %25 LEL.
2 End-of-line particulate filter (780248) MUST be removed when Pyrolyzer unit is calibrated/
bump tested with recommended gases other than target gases.
3 The Pyrolyzer unit requires a longer warmup time and a humidifier must be added in the
sample line when a dry calibration gas is applied to the detector directly from a target gas
cylinder
4 Recommended to keep the sample lines as short as possible where the RH condition at the
sample point is high (above %50 RH); there will be some sample loss due to absorption onto
the sample line.
5 When calibrating or bump testing NF3, sensor cartridges with Cl2, or HF, the charcoal Freon
filter (1830-0027) MUST be removed for calibration/bump testing then reinstalled for
monitoring.
6 Freon filter (1830-0027) is required for this application.
7 The most common failure in catalytic sensors is performance degradation caused by
exposure to certain poisons' (referred to as Catalytic Poisons). It is therefore essential that any
catalytic based gas monitoring system should checked regularly via bump tested (or re-
calibrated), more importantly after any gas release notification when there is a potential
poisoning based gases may be present. For further details contact Honeywell Analytics (please
ensure all gases that are potentially present in the area of detection are available prior to
contacting)
8 MIDAS S2-E-LEL cartridge carries the standard 2 years warranty but can be calibrated to
extend its life to 5 years. For the 2 years cartridges, Honeywell Analytics allows for a period of
up to 6 months after the manufactured date for cartridge installation and then 2 years of use.
If, for example, the cartridge is installed within the first 6 months, the expiration date will be 2
years after the installation date. If, however, the cartridge is installed more than 6 months after
the manufactured date, it will expire 2.5 years after the manufactured date. Contact your local
Honeywell Analytics Service Representative for more information.
