VI. RADIO COVERAGE FOR EMERGENCY RESPONDER WITHIN BUILDINGS

(See ADDENDUM “G”)

 

VII: TWO-WAY COMMUNICATION SYSTEMS

(See ADDENDUM “H”)

 

VIII: MEANS OF COMMUNICATIONS BETWEEN FIRE ALARM SYSTEMS AND SUPERVISING STATIONS.

Due to the lack of support and service by the telephone industry for the existing Public Switched Telephone Network (‘PSTN’) and Plain‐Old Telephone Service (‘POTS’) it is prohibited by the 2016 NFPA 72 section 26.6.4.1.4 to provide a Digital Alarm Communicator Transmitter (DACT) employing either POTS or cable telephone lines as single transmission means of communication between the protected premises Fire Alarm system and the off-site supervising station.

Since other transmission means of communication employing single technologies are permitted by the 2016 NFPA 72 Section 26.6.3.5, the SFFD is prohibiting the use of either POTS or cable telephone lines with a Digital Alarm Communicator Transmitter (DACT) for all new communicators installations.

New Fire Alarm systems:

All new Fire Alarm systems required by 2019 SFBC shall transmit the alarm, supervisory and trouble signals to an approved supervising station in accordance with the 2016 NFPA 72. The supervising station shall be listed as either UUFX (Central Station) or UUJS (remote & proprietary) by the Underwriters Laboratory Inc. (UL) or other approved listing and testing laboratory or shall comply with the requirements of FM 3011.

All new communicators shall employ either GSM (Cellular) or Mesh Radio (RF) technology as their required single technology communications means. If additional (Non-DACT) technology is requested to be provided on a non-required/voluntary basis, it may be approved by SFFD on a case-by-case basis.

The SFFD prohibits the use of IP-Based technology communicators as a single technology communication means due to their incompliance with the 2016 NFPA 72 Section 26.6.3.13 for the required 24 hours Secondary Power.

All new communicators shall be monitored for integrity at the FACU and at the supervising station for any communication or trouble condition.

Existing Fire Alarm systems:

It is recommended that building owners and/or Fire Alarm service companies be proactive and convert their existing Fire Alarm systems’ DACT communicators to a new Cellular or RF communicator prior to a potential catastrophic failure of the existing DACT telephone service. If an existing DACT communication means to the off-site supervising station is out of service due to a telephone service failure – a SFFD approved Fire Watch shall be provided until the required means of communications is restored.

The conversion process from an existing DACT to a new Cellular or RF communicator shall require a One-Dollar Over-The-Counter “FIRE only” permit and an associated fire inspection.

The permit application shall include, as a minimum:

1. A scope of work indicating: “Converting existing DACT to a new Cellular or RF communicator – ALL existing Fire Alarm system components and sequence of operation shall remain unchanged”

2. The existing previously approved Fire Alarm system sequence of operation matrix shall be provided with an indication: “The existing Fire Alarm system sequence of operation shall remain unchanged”

3. Current catalog cut sheets and CSFM listing sheets for the new proposed communicator.

4. Battery backup calculations for 24 hours standby plus 5 minutes of alarm (or 15 minutes of alarm for Voice Fire Alarm systems)

5. A floor plan or a diagram (not required to be to scale) showing the location of the new communicator as a NEW device and the existing DACT as “To be removed”

6. All new communicators are considered as “Control Equipment” and they shall have smoke detection at their installed location. If existing smoke detection does not exist at the installed location of the new communicator, a new smoke detection shall be provided.

7. All new communicators shall be monitored for integrity at the FACU and at the supervising station for any communication or power trouble condition.

 

IX: Wireless Zone Controller and NAC Extender shall be approved only under all of the following conditions:

A. All Wireless Zone Controller and NAC Extender systems’ components, design and installation, must be approved by SFFD on a “Fire Only” permit and must have associated Fire Inspection and Electrical Inspection per the approved permit.

B. Wireless Zone Controller and NAC Extender systems shall be permitted to be installed in existing buildings only (low-rise and high-rise buildings).

C. Wireless Zone Controller and NAC Extender systems shall not be permitted to be installed in existing buildings having an existing Emergency Voice Alarm Communications system (EVACS)

D. Wireless Zone Controller and NAC Extender systems shall not be permitted to be installed in existing buildings having existing smoke control systems in accordance with CBC Section 905 or 909.

E. Wireless Zone Controller and NAC Extender systems are only permitted to be connected or combined with the existing building Fire Alarm system as approved by SFFD on a case-by-case basis.

F. Wireless Zone Controller and NAC Extender systems shall be only permitted for use with separately listed compatible Fire Alarm Control Unit that must be UL certificated and meet SFFD AB 3.03 requirements for a new Fire Alarm system.

G. The installation of Wireless Zone Controller and NAC Extender shall be only permitted for use with separately listed compatible Fire Alarm Control Unit monitored by an approved off-site supervising station with a runner service (Central or Proprietary service only). See SFFD AB # 2.01 Section VII for the required means of communications between the Fire Alarm system and the off-site supervising station.

H. Wireless Zone Controller and NAC Extender Systems System shall be designed, installed and maintained per the applicable Edition of NFPA 72: National Fire Alarm and Signaling Code.

I. Wireless Zone Controller and NAC Extender systems’ components shall be listed for the purpose for which they are installed by Underwriters Laboratory Inc. (UL) or other approved listing and testing laboratory. They shall also have current California State Fire Marshal listing.

J. Wireless Zone Controller and NAC Extender systems shall include on the fire alarm permit plans a “Site Survey Record Sheet” showing all required equipment signal readings and proposed locations.

K. The San Francisco Electrical Code (SFEC) requires that the Wireless Input/output units be powered by a 15 or 20 ampere branch circuit within the dwelling unit and shall not be supplied by an existing receptacle circuit. It is permissible to power these devices from a dedicated circuit or an existing 120-volt smoke detector circuit. Arc-Fault Circuit-Interrupter Protection shall be provided for the wiring per SFEC 210.12. An accurate panel directory is required to reflect the modification to the system or circuit.
