Edwards SIGA2-HRS Rate of Rise Heat Detector Price in Bangladesh

Description

Product Name: Edwards SIGA2-HRS Rate of Rise Heat Detector Price in Bangladesh

Manufacturer: Edwards

Product Overview

The Edwards SIGA2-HRS operates as an intelligent addressable rate-of-rise heat detector engineered for commercial fire alarm systems. Furthermore, it monitors ambient air temperature changes to initiate an alarm when surrounding temperatures rise at approximately 15°F (9°C) per minute. It also includes a nominal 135°F (57°C) fixed-temperature thermal sensing element for comprehensive property protection.

In addition, as part of the Edwards Signature Series, the detector incorporates onboard microprocessor technology for digital processing, self-diagnostics, and automatic device mapping. Consequently, the unit transmits point-specific status data directly to compatible Signature loop controllers. Meanwhile, its plug-in design simplifies installation and servicing across standard, relay, fault-isolator, and audible detector bases.

Key Benefits

• Rapid Thermal Response: Detects fast-developing fires using a 15°F (9°C) per minute rate-of-rise thermal sensing threshold.

• Fixed-Temperature Backup: Triggers an alarm when ambient air temperature reaches the fixed threshold regardless of rise rate.

• Automatic Device Mapping: Transmits circuit position data to the controller to streamline system commissioning and maintenance mapping.

• Versatile Mounting: Plugs directly into standard, relay, isolator, or audible Signature Series mounting bases.

Key Features & Technologies

• Signature Series Intelligence: Processes thermal sensor data using onboard microprocessor technology and digital filtering to help reduce unwanted alarms.

• Individual Point Identification: Communicates unique addressable point details rather than operating as a conventional zone device.

• Dual-Color LED Indicator: Features a bicolor green/red LED that flashes green for normal polling and red during alarm conditions.

• Onboard Self-Diagnostics: Continuously evaluates internal circuits and maintains event history in nonvolatile memory.

• Construction & Housing: Molded from high-impact engineering polymer with a low-profile plug-in profile.
