The E2S GNExCP7-PT in High-Visibility Yellow (Full Configuration Code: GNExCP7PTDPLBS3A1YNExxxRSxxxR / GNExCP7-PT Push Button MCP Series) is a high-reliability explosion-proof manual alarm and ESD station manufactured by E2S Warning Signals (UK) with 100% UK Origin. Molded from corrosion-proof, UV-stable Glass Reinforced Polyester (GRP) in an eye-catching yellow finish, this manual call point is specifically engineered for gas leak warning, process alarm signaling, and Emergency Shutdown (ESD) initiation across hazardous industrial environments (Zone 1, Zone 2, Zone 21, and Zone 22).

KEY PRODUCT FEATURES AND OPERATIONAL ADVANTAGES:
1. Ergonomic Push Button Mechanism with Protective Lift Flap:
Features a tactile push button actuator protected by an integral spring-loaded transparent lift flap. This configuration prevents accidental tripping while allowing rapid, decisive alarm triggering during plant emergencies without requiring glass replacement.
2. Robust Yellow GRP Corrosion-Free Housing:
Molded from high-grade flame-retardant, anti-static GRP in high-visibility Yellow (RAL 1003). Free of external metallic components prone to corrosion, it is completely immune to offshore salt spray, aggressive chemicals, and UV degradation with an IK09 impact resistance rating.
3. Universal Global Explosion-Proof & Marine Certifications:
Certified to rigorous international standards including ATEX, IECEx, and UKCA with ratings Ex db IIC T6 Gb and Ex tb IIIC T80°C Db, making it suitable for hazardous gas groups IIA, IIB, and IIC (including Hydrogen) as well as combustible dusts. Certified SIL 2 compliant in accordance with IEC 61508.
4. Integrated End-Of-Line & Series Monitoring Resistors (ExxxRSxxxR):
Pre-configured with built-in series and End-Of-Line (EOL) resistors, allowing fire & gas panels, DCS, and ESD controllers to continuously monitor line integrity, detect open/short-circuit faults, and verify activation status precisely.
5. IP66 / IP67 Ingress Protection:
Sealed with high-grade elastomeric gaskets to prevent ingress of fine dust, driving rain, and high-pressure washdown water jets, ensuring maximum internal switch contact protection.
6. Versatile Conduit Entries & Generous Wiring Space:
Equipped with dual M20 cable entries (with optional 1/2" NPT / 3/4" NPT adaptors) and a spacious internal terminal chamber for fast termination of heavy armored offshore cables.
