The Tyco 711PH (Part Number: 516.900.102) is a microprocessor-based conventional optical smoke and heat multi-sensor detector with rate-of-rise heat enhancement. It is part of the Tyco 700 Series and is designed primarily for marine environments, though it is also suitable for land applications.
Key Capabilities & Design
- Dual Detection Technology: Combines optical smoke scatter sensing with a rapid rate-of-rise temperature sensor that automatically increases smoke detection sensitivity when a quick temperature jump occurs.
- Drop-In Compability: Serves as a direct, backwards-compatible replacement for the legacy Tyco 600 Series (such as the 601PH-M).
- Microprocessor-Based Design: Features improved detection algorithms and built-in drift/threshold compensation to extend service life and minimize false alarms.
- Air Sampling: Samples ambient air every 5 seconds, drawing a signaling current upon detecting a fire condition.
- Base Compability: Compatible with standard Tyco bases including 4B, 4B-D, 5B, and 5B-D.
- Certifications: Approved to EN54 standards (including EN54-29, LPCB, Marine Equipment Directive (MED), and major IACS classification societies for vessel use.
- Design Features: : Low-profile, discreet physical build with an integrated insect mesh.
