SUMMARY OF REQUIREMENTS

The following is a brief summary of the new and revised paragraphs in the Standard for Control Units And Accessories For Fire Alarm Systems, UL 864, which have a future Effective Date of October 17, 2014 and the action that may be required to determine compliance.

Paragraphs General Subject and Comment This review applies to the following products:  Local Type units Listed under CCN UOJZ,  Releasing control units Listed under CCN SYZV, and  Emergency Communication and Relocation Equipment Listed under CCN UOQY.

33.3.1 (revised) Revised to permit NACs to additionally be used for other Life Safety Functions.

Manufactures wishing to specify connection of other than notification appliances to a product’s NAC, will need to submit a wiring diagram to UL delineating the other devices/appliances. UL will review the information and determine the extent of the assessment to confirm compatibility and any other operational concerns. The interconnected devices/appliances will need to be UL Listed for the intended application.

No testing or review of installation documentation is needed to comply with the revision to this clause if other Life Safety function devices are not to be specified.

33.3.1.1 (new) Each system will now be required to have the capability to provide at least one regulated NAC circuit as defined in clause 61.2.

The rationale for the new requirement stated: The proposed new wording acknowledges and supports the concept that systems should provide at minimum a simple and field verifiable means for connection to non-proprietary and/or legacy equipment which may be AHJ and/or specific building application life safety driven. Often the actual installation will need to be custom designed/configured within the constraints of good engineering practice and/or NFPA/ICC/Local code by competent field personal utilizing additional equipment resources available at the time of installation for optimum life safety performance. In some cases this additional equipment may even be already installed on site (legacy), and in the interest of affordable optimum life safety still suitable for the intended use. In both above cases a regulated NAC defines simple circuit operating parameters, which are, both good applications engineering practice and readily field verifiable Subject: 864 Page 2 of 3 April 30, 2010

Paragraphs General Subject and Comment by the AHJ and building stakeholders.

Compliance with this requirement can be accomplished by, but not limited to, one of the following: 1. For systems that do not currently have regulated NAC(s), an option to meet this requirement without additional testing would be to accept a rating of 10% of the existing special application NAC current rating. This would involve an installation documentation update. This would be a paperwork only project review for UL 864. Multiple ratings may be applied to the same NAC. 2. For a NAC without a regulated rating to obtain higher than 10% ratings additional testing to 61.2 of UL 864 would be required. 3. Use of interconnected Listed accessories, which provide a REG rated NAC.

Options 1, 2, and 3 will necessitate the submittal of a wiring diagram/installation instruction delineating revised ratings and/or interconnected products to meet the requirement. UL will review the information and confirm the extent of the assessment to confirm compliance.

Option 2 will require the manufacturer to submit samples of a representative system for testing.

No testing or review of installation documentation is needed for systems currently employing at least one REG rated NAC.

61.2.1.3 (new) The requirements of 33.3.1.1 can be met by providing multiple ratings on 61.2.1.1 (revised) a NAC, as long as one of the ratings is a regulated rating. 61.2.1.1 revised to permit a NAC to be identified by more than one of the rating designations shown in Table 61.1 Voltage types and ratings Rating designation Voltage type Maximum RMS voltage range limits Regulated 12 DC DC 8 - 17.5 Regulated 24 DC DC 16 - 33 Regulated 12 FWR FWR 8 - 17.5 Regulated 24 FWR FWR 16 - 33 Regulated 120 AC AC 96 - 132 Regulated 240 AC AC 192 - 264 Special application Any Rated

See 33.3.1.1 (new) for comments.

61.2.1.2 (new) New requirement stating: NAC circuits that employ integral signaling schemes, or that connect to separate devices (e.g. synchronization modules) employing signaling schemes, to synchronize, to activate and deactivate subsets of the appliances on a NAC, or to change the output (e.g. color or tone) of appliances, shall be evaluated as special applications when assembled in a system with those devices/appliances. This does not preclude these circuits from also being evaluated and Subject: 864 Page 3 of 3 April 30, 2010

Paragraphs General Subject and Comment marked as regulated circuits when used with other devices/appliances that do not require these signaling schemes.

The requirement of 33.3.1.1 that at least one NAC in each system meet the REG rating applies to the voltage output rating for a NAC. Where the NAC/system employs either an integral signaling scheme or connection to separate devices to provide a signaling scheme, such as synchronization, a sample of the representative system will need to be submitted and subjected to faults on the NAC consistent with the style/class rating for the NAC. Relative to the action needed to now comply with this requirement, this applies to products with NACs newly rated for a REG voltage rating and employing integral signaling schemes and existing NACs with new interconnections to separate devices employing signaling schemes.

No new fault testing will be required where previously tested REG rated circuits are now specified to be used with devices/appliances that do not require signaling schemes.
