Core offering

The Protectowire Co., Inc. designs and manufactures linear heat detectors (PHSC, CTI™, fiber optic), interface modules, fixed-mount dual-sensor thermal cameras, Spectrex UV/IR and IR3 flame detectors, and FireSystem control panels for fire detection in special hazard industrial environments. Products are engineered for extreme conditions (from -60°F to 2192°F operating ranges) and sold exclusively via a global network of factory-trained authorized distributors who design, install, and service fire protection systems for end customers.

Product overview

Protectowire Co Inc is an industry leader in linear heat detection technology since 1938, offering an integrated fire detection portfolio centered on linear heat detectors with complementary detection and control products. The core product lines include Standard Digital (PHSC/PLR) and Confirmed Temperature Initiation (CTI™) linear heat detectors using polymer/thermocouple technologies, supplemented by Fiber Optic linear heat detectors for long-range restorable applications. Interface modules (PIM-530, PIM-230, PIM-120 for PHSC; CTM-530, CTM-230 for CTI) connect detectors to fire alarm control panels via Modbus RS-485. PWTC thermal camera series (PWTC-20, PWTC-100, PWTC-200) provide thermal/visible imaging for continuous monitoring. Spectrex flame detectors (40/40D, 40/40C, 20/20 series) add UV/IR and Triple-IR detection capabilities. FireSystem control panels (SRP-4×4, FS 2000, FS 2600) manage complete fire alarm systems. Comprehensive installation accessories, initiating devices, and training services support the full product lifecycle.

Products and services

• Standard Digital (PHSC/PLR) Linear Heat Detector Digital linear heat detector using heat-sensitive polymer that weakens at fixed temperatures, allowing twisted spring steel conductors to contact and trigger an alarm signal. Available in PHSC (steel conductors) and PLR (low-resistance) models with multiple jacketing options for harsh industrial environments. Sold through authorized distributors for fire protection system integrators.
• Confirmed Temperature Initiation (CTI™) Linear Heat Detector Patented thermocouple-based linear heat detector using dissimilar metal conductors. Provides temperature verification and exact alarm point location, and uniquely distinguishes between physical damage shorts and true thermal alarm conditions via short circuit discrimination to eliminate false alarms in harsh industrial settings such as mining conveyors, oil and gas, and power generation.
• Fiber Optic Linear Heat Detector Restorable continuous linear thermometer using quartz fibers in a low-smoke zero-halogen jacket, with a fiber controller calculating temperature from Stokes/anti-Stokes backscatter frequency ratios. Immune to EMI/RFI, supports zones up to 30,000 feet, and detects temperature rises as small as 1°C per minute. Designed for tunnels, transit infrastructure, and long-run industrial assets.
• PWTC Series Fixed-Mount Thermal Cameras Fixed-mount dual-sensor thermal imaging cameras (PWTC-20, PWTC-100, PWTC-200) combining thermal measurement with visible-light video for continuous condition monitoring and early fire detection. Features onboard analytics for temperature anomaly detection, configurable pre-alarm and alarm thresholds, IP66/IP67 ratings, and Modbus TCP integration with facility management systems.
• Spectrex™ SharpEye Flame Detectors (40/40D, 40/40C, 20/20 Series) UV/IR, multi-IR, and QuadSense Triple-IR (IR3) flame detector families for ultra-fast hydrocarbon and gas flame detection. Distributed by Protectowire under partnership with Spectrex; covers detection ranges up to 300 ft (90m) with response times under 50 ms for hazardous-area industrial fire protection.
• FireSystem SRP-4×4 Multi-Purpose Control Panel Multi-purpose fire alarm control panel for commercial and light industrial detection and extinguishing. Features programmable I/O circuits, Class A/B initiating circuits, monitors up to 10,000 feet per zone, built-in relays, and UL/FM/CSFM approvals.
• FireSystem 2000 (FS 2000) Control Panel Customizable commercial and light-industrial fire alarm control panel with individual control modules; expandable from a basic two-zone system to 46 zones, monitors up to 5,000 feet per zone and up to 30 smoke detectors per zone, UL-listed and FM-approved; configured to project specifications.
• PIM and CTM Interface Module Family Standalone interface modules (PIM-530, PIM-230, PIM-120 for PHSC; CTM-530, CTM-230 for CTI) that translate linear heat detector signals for fire alarm control panels and addressable nodes. Provides integrated alarm point location, Modbus RS-485 output, relay contacts, event history logging, and graphical-LCD or LED indication depending on model.
• Distributor Training Services Fee-based training program including 3-day in-person sessions at the Pembroke, MA headquarters covering linear heat detectors, CTI, interface modules, thermal cameras, and control panels, plus online courses (All-In-One, Digital LHD, CTI, Industries & Applications) sold via Protectowire.myshopify.com. Designed to certify authorized distributors globally.
