PI #356 / FR #3510 52

Proposed Changes SIG-TMS New 720 Requirements! FR 4511, PI 357 FR 4513, PI 359 FR 4514, PI 360 Reason: The Technical Committee provides new language to incorporate NFPA 720 requirements into Chapter 14 in accordance with the guidance of the Correlating Committee. 53

Proposed Changes SIG-TMS New 720 Requirements! Adds New Section 14.4.5.4.2 Carbon monoxide alarms shall be replaced when either the end-oflife signal is activated or the manufacturer s replacement date is reached. Reason: The Technical Committee adds this section in accordance with guidance from the Correlating Committee to incorporate NFPA 720 into NFPA 72. PI #358 / FR #5050 54

Proposed Changes SIG-TMS New 720 Requirements! FR 4515 Adds Annex (H) Material Reason: The Technical Committee provides new language to incorporate NFPA 720 requirements into Chapter 14 in accordance with the guidance of the 720/72 Consolidation Task Group. FR 4519 Removes Annex material Reason: Removes Annex material due to NFPA 720 being withdrawn. PI #378 / FR #4515, 4519 55

Proposed Changes SIG-TMS FR 4522, FR 4523 The Technical Committee edits the text to be consistent with the new proposed definition of official correspondence and adds the word deficiency to be consistent throughout the section. FR 4524 The Technical Committee edits text to be consistent with the new proposed definition of official correspondence, and provides new language in the Annex to address the need to take into account manufacturer tolerances for equipment operability, especially where environmental conditions are not optimal. PI #15, 16, 26 & 209 FR #4522, 4523 & 4524 56

Proposed Changes SIG-TMS New Section 3.3.84 Electromechanical Releasing Device. Mechanical devices, including fusible links, electrically monitored for contact closure to initiate a signa to the FACU.

Proposed Changes SIG-TMS FR 4505 Correlation in Section No. D.3.2.3 Reason: The Technical Committee revises the text to replace panel with unit and thereby correlate with the definition of an Emergency Communications System Control Unit in Chapter 3. FR 4506 Editorial Change in Sections 14.2.2.2.3, 14.2.2.2.4 Reason: The Technical Committee removed the words "in writing" because they were found to be unnecessary. PI #340 / FR #4505 & 4506 59

Proposed Changes SIG-TMS FR 4528 Correlation Issue in Section No. F.1 Reason: The Technical Committee edits the text in line with a review conducted by the Correlating Committee and for consistency with Chapter 12. Class R and Class S have been removed from Chapter 12 and Class N has been added. The above text will harmonize accordingly. FR 4531 Table Modification in Section No. A.14.6.2.4 Reason: The Technical Committee modifies column GG and replaces "exterior strobe" with "exterior visible notification appliance". This is done as part of the Correlating Committee Task Group on terms, the term "light" and strobe was reviewed throughout the entire document for proper use. In some cases it refers to a physical appliance while other sections use it to refer to the output of an appliance. In this section the term is for an appliance and the proper term "visible notification appliance" should be used. PI #717 / FR #4528 & 4531 60

Proposed Changes SIG-TMS FR 4526 Editorial Change D.3.2 Emergency Communication Communications Equipment. FR 4525, PI 465 Editorial Change Reason: Correlate with task group work done by the Correlating Committee FR 4527 Removes redundant language in Section No. D.2.5.4 PI #466 / FR #4526 & 4527 61
