Dcr1 S1 Standard Config

(DCR1-T1)

The Self-Testing DCR1-T1

All the capabilities of the standard DCR1 with self-testing capabilities.

Let’s Talk Specs

Built-In Verification for Demanding Processes

The DCR1-T1 adds automated optical self-test to the standard DCR1 platform. Detection performance, chemical-resistant housing, and approvals are identical to the DCR1-S1.

This configuration is selected when detectors are installed in locations with limited physical access, when scheduled manual testing is disruptive or difficult to coordinate, or when facility specifications require ongoing automated verification of detector health.

The DCR1-T1 does not include FEP cable or enhanced relay connections.

Installation Manual

Key Features

  • Automated Optical Self-Test: Periodically verifies sensor and optical window integrity. Faults reported via relay output and LEDs.

  • UV/IR Multi-Spectrum Sensing: UV and IR sensors. Calibrated to detect a 4-inch IPA fire at 10 feet on axis within 3 seconds.

  • Chemical-Resistant Housing: Factory-sealed FRPP with sapphire windows. IP67 rated. UL 94 V0 flammability rated.

  • Inside-the-Process Placement: Designed for installation inside semiconductor tools, gas cabinets, wet benches, and more.

Let’s Confirm the Right Configuration

If your project requires automated self-test without FEP cable or enhanced relay outputs, Sierra can help confirm the DCR1-T1 is the right configuration.

The Engineering Behind the DCR1-T1

The DCR1-T1 uses the same multi-spectrum UV/IR detection algorithm and continuous fault diagnostics as every DCR1 model.

The self-test function periodically verifies that the optical path and sensors are operating correctly without requiring physical access to the detector.

Internal diagnostics also monitor input voltage, sensor circuits, relay integrity, and temperature. If any fault condition is detected, the Fault Relay de-energizes and the LEDs indicate the fault type. This gives operators and control systems visibility into detector health between scheduled inspections.

What Sets Sierra Apart

Sierra Safety Technology has manufactured flame detection equipment for nearly 40 years with zero product recalls and zero failures resulting in loss of life. DCR1 detectors continue to deliver reliable service in semiconductor fabs and chemical plants where chemical exposure is constant and access for manual inspection is limited.
