20) Be aware that extended exposure of a detector element to certain concentrations of combustible
gases and air can introduce stress to the element that may seriously affect its performance, and
therefore recalibration should be carried out or the sensor replaced, or both, after an alarm due to an
indication of a high concentration.
21) When used in a Gas Detection summing up role, the gas reading may be higher than the actual
concentration at any one detector head location, or it may be the actual concentration at one specific
detector head.

1.1 Cautions

1) Touchpoint Plus SMPS and Input / Output Modules have no user serviceable parts. In the unlikely event
of a failure, the item must be replaced using only manufacturer supplied parts.
2) Do not use sharp objects to operate the touchscreen as this could irreparably damage the User Interface
and adversely affect its IP rating.
3) Use only soft, damp cloths or screen wipes to clean the Touchpoint Plus. Do not use solvents or abrasives
as they will damage the User Interface.
4) Once commissioned, Touchpoint Plus is intended for continuous operation.
5) Undo the security screws before pulling the locking handle. Failing to do so may irreparably damage the
enclosure.
