Once correctly installed, the TS4000H requires little maintenance. For optimum performance,
General Monitors recommends establishing a calibration check schedule and that the complete
system, including all alarm circuitry, is tested annually.
The mounting and overall dimensions for the TS4000H should be used when making
installation determinations. For Mechanical Specifications, refer to Section 9.5.
3.3.1 Intrinsic Safety Barrier
The TS4000H has an Intrinsic Safety Barrier within the Interface Module. The Intrinsic Safety
Barrier allows the user to change (hot swap) the electrochemical cell without powering down
the TS4000H and without declassifying the area. The TS4000H can be used in a hazardous
area without additional hardware.
3.3.2 Electrochemical
Cell
Maintenance
The removal of particulates from the electrochemical cell must be done using compressed,
instrument grade air. The air nozzle must be kept at a distance to prevent damaging the cell by
the force of the air current. Solvents must never be used.
WARNING:
To avoid injury, use extreme caution when using compressed air.
Some typical items to check during maintenance examinations are:
Electrochemical cell mounting, to see that it is secure
Electrochemical cell cleanliness, to see that it is clear of oil, water, dust, or paint
Cable connections for tightness and possible damage
All detector placements are up-to-date with the layout of the facility
If the facility has been altered, placement may need to be adjusted
3.4 Mounting Instructions
Mount the TS4000H using the bolt holes on the Base Unit. For easy access and readability, the
Base Unit may be mounted away from the Interface Module (remote configuration).
NOTE:
For remote configurations, an additional explosion proof junction box must be used.
Refer to Section 3.4.3 for remote mounting information and Section 9.5.1 for junction
box information.
