DP4801Ex — ATEX/IECEx Zone 2 & 22 DMR with 2.4" Color Display, Full Keypad, and Man-Down Alert
Hazardous-area DMR portable certified ATEX/IECEx Zone 2 & 22 — gas and dust environments present during abnormal operation. 2.4-inch full-color display with alphanumeric keypad for direct SMS dispatch, enhanced GPS/GLONASS with man-down accelerometer for automatic lone-worker alerts, and AES-256 encryption on the DMR digital platform. The operational flagship for refineries and LNG terminals already standardized on DMR/MOTOTRBO infrastructure: same hazardous-area compliance as the classic DP4401Ex with text dispatch, workforce tracking, and lone-worker safety added — the digital upgrade path for existing DMR fleets entering classified areas.
MTP8550Ex — ATEX/IECEx Zone 1 TETRA with Class 3L 1.8W Adaptive Output and TEA End-to-End Encryption
TETRA portable certified ATEX and IECEx Zone 1 — explosive gas present during normal operation, the highest continuous-hazard tier. Class 3L 1.8W adaptive RF output self-regulates in hazardous zones. TEA end-to-end encryption secures voice and SDS data terminal-to-terminal — impossible on the DMR platform. Gateway/repeater mode extends coverage without added infrastructure. 1,850mAh Li-Ion battery delivers 16 hours. The mission-critical choice for offshore platforms, petrochemical plants, and LNG terminals where continuous-hazard zones, digital trunking, and terminal-to-terminal encryption are contractual requirements — the premium tier that justifies a 3-4x price premium over Zone 2 DMR units.
