TECHNICAL NOTE : Scope of the Philippine Electrical Code (PEC) on Fire Detection, Fire Protection, and Fire Alarm Systems

1. Introduction

The Philippine Electrical Code (PEC) 2017 Part 1 provides minimum safety standards for the installation of electrical systems, including those associated with fire detection, fire protection, and fire alarm systems. While the PEC does not define performance or detection thresholds, it governs the electrical wiring, protection, and interconnection of these critical life safety systems.

This technical note summarizes the relevant PEC scope, clauses, integration with other codes, and compliance requirements.

2. Scope of PEC on Fire Safety Systems

The PEC focuses on ensuring that the electrical components of fire alarm and fire protection systems are installed safely and reliably. It does not cover design specifics (e.g., detector spacing, response times), which fall under RA 9514 (Fire Code of the Philippines) and NFPA 72 (National Fire Alarm and Signaling Code).

3. Annotated PEC Excerpts

3.1. Article 760 – Fire Alarm Systems

Clause Provision Annotation
760.1 Scope Covers wiring and equipment for fire alarm systems.
760.21 Mechanical execution Requires neat and secure installation.
760.24 Mechanical protection Requires secure support at ≤ 1.4 m spacing.
760.25 Abandoned cables Prohibits abandoned fire alarm cables.
760.41 Circuit identification Prevents unintentional mixing with other systems.
760.121 Power sources Requires a dedicated branch circuit.
760.176(B) Pathway survivability Requires 2-hour rating in critical areas.
760.179 Cable types FPL, FPLR, and FPLP for general, riser, and plenum areas.

3.2 Article 695 – Fire Pumps

 

Clause Provision Annotation
695.3 Power source Must have a reliable, dedicated power source, not subject to shutdown by fire alarm or load-shedding systems.

3.3 Article 700 – Emergency Systems

Clause Provision Annotation
700.12 Emergency power Fire alarm and life safety systems must be supplied by emergency power, separate from normal loads.

4. Related Codes and Standards

Code Relevance
RA 9514 – Fire Code of the Philippines Governs fire safety requirements, including where fire alarm and detection systems are required.
NFPA 72 Defines design, installation, testing, and maintenance of fire alarm systems.
National Building Code (PD 1096) Establishes building occupancies and architectural fire protection needs; requires compliance with PEC for all electrical installations.

5. PEC Compliance Checklist (Electrical Scope)

 Requirements Reference
Fire alarm system circuits are dedicated Sec. 760.121
Fire alarm circuits identified and segregated Sec. 760.41
Fire alarm cables are type FPL/FPLR/FPLP Sec. 760.179
Pathway survivability (2-hour rating if required) Sec. 760.176(B)
Mechanical protection and support verified Sec. 760.24
Abandoned fire alarm cables removed Sec. 760.25
Fire pumps powered by a dedicated reliable source Sec. 695.3
Emergency power provided for alarms, egress Sec. 700.12

6. Summary

The PEC ensures that the electrical infrastructure supporting fire alarm and protection systems is safe, reliable, and code-compliant. However, complete system design requires integration with:

  • RA 9514 for statutory compliance
  • NFPA 72 for performance and functional requirements
  • NBCP for building occupancy and architectural considerations

Electrical engineers must ensure proper coordination across all codes and provide clear labeling, dedicated circuits, physical protection, and emergency power supply for all fire-related systems.
