The E2S GNExCP7-PT (Full Configuration Code: GNExCP7PTDPLBS3A1RNExxxRxxxR / GNExCP7-PT Push Button MCP Series) is a high-reliability explosion-proof manual alarm station manufactured by E2S Warning Signals (UK) with 100% UK Origin. Constructed from robust, corrosion-proof, UV-stable Glass Reinforced Polyester (GRP), this manual call point is specifically engineered to provide manual initiation of fire, gas alarm, and emergency shutdown (ESD) systems in the world's harshest onshore and offshore hazardous 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 activation while allowing rapid, decisive alarm triggering during emergencies without the need to replace broken glass elements.
2. Robust Glass Reinforced Polyester (GRP) Corrosion-Free Housing:
Molded from high-grade flame-retardant, anti-static GRP material. Free of external metallic components prone to atmospheric corrosion, it is completely immune to offshore salt spray, harsh 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 (ExxxRxxxR):
Pre-configured with built-in series and End-Of-Line (EOL) resistors, allowing fire alarm panels and DCS 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 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.
