When the alarm sounds, everyone has to hear it. MHA AUTOMATION designs, installs and commissions Public Address & General Alarm (PAGA), intercom and telecommunication systems — and the fibre and data cabling beneath them — for vessels, offshore platforms, terminals and plants across Malaysia and Singapore.
PAGA — Public Address & General Alarm — is the system a vessel or plant depends on in its worst five minutes. We engineer PAGA installations that stay audible and intelligible across engine rooms, decks and process areas, and we deliver them the way safety systems should be delivered: engineering design and study, supply, installation, then documented testing and commissioning. As a partner of ARMTEL, we deliver industrial PAGA and intercom platforms engineered for high-noise, high-humidity, chemically aggressive and explosive environments — see the featured ARMTEL hardware below.
Alongside PAGA we install public address and intercom systems — including industrial and explosion-proof intercom for hazardous zones on tankers, terminals and platforms — plus wider telecommunication systems, so day-to-day operational comms and emergency comms are engineered together rather than bolted on separately. A recent reference: integrated security CCTV and intercom delivered for a boiler lift at Malakoff's Tanjung Bin power plant.
Communication systems are only as good as the cabling under them. Our teams run and terminate fibre-optic cabling with splicing and structured data cabling to marine standards, and deliver 5G network connectivity for maritime vessels — high-bandwidth, low-latency shipboard connectivity for operations, remote monitoring and crew welfare — the same infrastructure that carries our marine CCTV and surveillance systems, which is why the two scopes are often delivered in one mobilisation.
MHA AUTOMATION is a PETRONAS-licensed, 100% Bumiputera, ISO 9001:2015 certified company based in Masai, Johor — serving FPSO, FSO, FSU, LNGC, Oil Tanker and OSV vessels, offshore platforms and industrial plants since 2014, on land and at sea, around the clock.
Industrial PAGA & intercom equipment from our partner ARMTEL — full range and specifications in the brochure or on request.
Digital PA/GA & Intercom Core
Compact central exchange of the Armtel DCN digital intercom and PA/GA system — up to 240 subscribers over 16×E1 ports, ISDN PRI trunk to external PBX, alarm broadcasting from voice memory, and remote monitoring and diagnostics over IP.
Hybrid IP Communication Platform
Core of the ArmtelICS hybrid system: SIP registration, call routing and wideband-codec transcoding on x86 hardware — unlimited SIP capacity, 1+1 server redundancy, Modbus TCP integration with F&G and automation, PBX interworking via ISDN PRI or SIP.
Weatherproof & Ex-proof IP Call Stations
Loud-speaking outdoor call stations for harsh industrial sites — IP66, HD voice up to 14 kHz, SIP and Armtel-IP, ADSL links up to 6.5 km and redundant dual Ethernet. DWEx-IP2 is certified II 2 G Ex db eb ib IIC T4 Gb / II 2 D Ex tb IIIC T135°C Db for explosive gas and dust zones.
Dispatcher Console & Desktop Stations
A 10.1" colour-touchscreen dispatcher console and key-based desktop call stations for centralized or decentralized intercom and PA/GA — redundant dual Ethernet, SIP and Armtel-IP, HD Voice 14 kHz, noise and echo cancellation, PoE+ power and key-expansion units.
100 V PA Power Amplifiers
Single- and dual-channel class-D digital amplifiers for 100 V public-address lines — over 85% efficiency with transformer isolation, 110/230 VAC mains with 48 VDC standby auto-switchover, and built-in protection against overvoltage, short-circuit, idle running and overheat.
Weatherproof & Ex-proof Horn Loudspeakers
Rugged 25 W horn loudspeakers for intercom and PA/GA broadcast in harsh outdoor and chemically aggressive environments — IP66/67, up to 124 dB SPL, −55…+70 °C. AR-25Ex carries 1Ex d e mb IIB T4 Gb / Ex tb mb IIIC T135°C Db explosion protection.
PAGA (Public Address & General Alarm) is the safety-critical system that broadcasts alarms and announcements across a vessel, platform or plant. Yes — we design, supply, install, test and commission PAGA systems for marine and industrial sites, including hazardous areas.
Yes. We deliver public address and intercom systems — including industrial and explosion-proof intercom for hazardous areas — as well as wider telecommunication systems for vessels, terminals and plants.
Yes. Our scope covers fibre-optic cabling and splicing plus structured data cabling, so the communication backbone and the systems riding on it are installed and commissioned by the same team.
Tell us the vessel or site — we'll propose the right system, cabling and commissioning plan.
