SAFETY
Ensure that you read and understand this handbook BEFORE installing/operating the equipment.
Pay particular attention to the Safety Warnings.
WARNINGS
1. Thisgasdetectionequipmentiscertiedforandintendedforuseinpotentiallyhazardous
areas. Install and use the equipment in accordance with current local and national
regulations.
2. Refertothecontroldrawingsincludedinthisdocumentwheninstallingthecertied
components.
3. Operators should be fully aware of the action to be taken if the gas concentration exceeds
alarm level.
4. Donotmodifyoraltertheconstructionofanyoftheunitsasessentialsafetyandcertication
requirements may be invalidated.
5. The equipment is not suitable for use in oxygen enriched atmospheres (>21%V/V). Oxygen
decientatmospheres(<10%V/V)maysuppresssomesensoroutputs.
6. The equipment is intended for use at atmospheric pressure only and should not be used in
pressures exceeding 1.1 bar.
Transmitter Unit only
1. INPUT VOLTAGE MUST NOT EXCEED THE STATED MAXIMUM (32V DC) AS
ESSENTIAL SAFETY REQUIREMENTS MAY BE INVALIDATED AND THE UNIT MAY BE
PERMANENTLY DAMAGED.
2. Alarmsshouldnotberesetuntilitisconrmedthatgasisnot present.
3. Hazardousvoltagesmayexistatalarmcontacts.Ensurepowerisdisconnectedatsource
prior to servicing contacts.
4. Gas events occurring while accessing the Transmitter Unit menus will not be reported locally.
5. Overrangeammablegasreadingsmayindicateanexplosiveconcentrationofgas.
Certied Sensor only
1. WheninstalledtomeasureammablegasitisessentialthateithertheTransmitterunitor
controlnetworkisconguredtolatchtheoverrangecondition.IftheTransmitterunitlocal
relays are used this should be achieved by enabling the overrange latching function of the
Transmitterunit.Depletionofoxygenasaconsequenceofdisplacementbyammablegas
canresultinthegasreadingreturningtozero.
2. Change gas cartridges using the procedure described in this handbook. Failure to correctly
follow the procedure could result in the wrong cartridge being installed, and possibly non-
detection of events. Alternatively, extraneous alarms could be triggered by chemicals
detected but not of concern at a particular location.
3. Sensor cartridges may contain corrosive solutions. Dispose of in accordance with local and
national regulations.
4. Duringusage,assomegasesmaybehazardous,outletsfromaccessories,etc.,e.g.Flow
Housing, should exhaust to a safe area.
