Caged beacon, visible from the yard
A red beacon sits above the housing behind a steel wire cage. It flashes with the call state, so the phone can be found by sight as well as sound, and the cage protects the lens from knocks and falling tools.

Overview
Clear calls in high noise.
The KT-M-KTS2 is designed for wall mounting in loud, exposed locations. Its impact-resistant composite housing protects the telephone on construction sites, in tunnels and around heavy plant, while the 30W loudspeaker amplifies the ring so a call can be heard across the area.
The phone stores multiple speed-dial numbers and detects an incoming ring before switching on automatically. The call is broadcast through the speaker, and a flashing LED beacon plus status lights show what the telephone is doing. SIP, analog and direct fiber connections are available, with PoE or 12V, 24V and 220V power options.
Capabilities
Key features
30W area-filling audio
A 30W loudspeaker turns the ring and hands-free voice into an alert that carries across a yard, tunnel or plant floor.
Caged beacon above the housing
A red beacon sits behind a steel wire cage and flashes with the call state, so the phone can be found by sight as well as sound.
M1 / M2 / M3 plus emergency
Three speed-dial keys and a separate red emergency button sit below the full dial pad, all on a silicone keypad built for gloved use.
IP65 composite housing
The sealed composite shell measures 300 × 180 × 140 mm and mounts on a wall in construction sites, tunnels and exposed plants.
Private handset, armored cord
Lift the handset for a private conversation on a stainless armored cord with a strain-relieved entry at the housing.
Direct IP calling, no PBX
Call another phone by IP address with no registrar or server in between, or register up to three SIP accounts for normal use.
Marking and manual alarm
Function keys can mark up to eight target phones, fire a stored alarm over multicast or UDP, or join a multicast paging group.
220V, PoE or DC power
Runs from 220V mains with PoE or DC available as options, and a direct fiber connection can be specified for long campus runs.
Built details
Built to be heard across the yard.
The KT-M-KTS2 is a composite speaker telephone for construction sites, tunnels, plants and other loud, exposed places. A 30W loudspeaker turns the ring into an area alert, while the handset gives the caller a private conversation on a stainless armored cord. The keypad carries the full dial pad, three speed-dial keys and a separate red emergency button. Behind the panel, the same V3s control board and firmware used across the Safecom range handle the call.
M1 / M2 / M3 plus a red emergency key
Below the dial pad are three speed-dial keys and a separate red emergency button. Each key can hold a different destination, so the caller does not need to remember a number. The silicone keypad is built for gloved use.
30W speaker and an armored handset
The 30W loudspeaker carries the ring and hands-free audio across a noisy floor. When the caller needs privacy, the handset hangs on a stainless armored cord with a strain-relieved entry at the housing.

Discuss your siteThe shared platform
One control core. Four kinds of armor.
Waterproof, explosion-proof, cleanroom and intercom phones are not four different phones inside. They share one Allwinner V3s control board and one firmware; the site conditions decide the enclosure, keypad, handset, buttons and beacon around it. Every model can also call another phone directly by IP address, with no PBX in the path.

What changes
Waterproof
Sealed composite shells with gasketed doors, caged beacons and armored handset cords. The same board works in a roadside cabinet, a tunnel phone or a solar tower.
- IP65 / IP66 sealed housing, cabinet or post
- Full keypad, two-button or one-button face
- Caged beacon, handset or hands-free audio
Inside every version
Same board. Same firmware. Same menus.
The web interface on a waterproof phone is the same interface on the explosion-proof and cleanroom units. The enclosure changes what the firmware can drive — a beacon here, a relay there, a camera on the door panel. The call flow, paging stack and alarm logic do not change, and two phones can call each other directly by IP address without a PBX or registrar.
- One control coreAllwinner V3s, one board across all four ranges.
- One firmware imageSIP, call handling, marking, broadcast, alarm and I/O.
- One web interfaceThe same menus, status page and provisioning on every model.
- No PBX requiredAny two phones can call each other directly by IP address.
Live status page
Each input, relay, LED and function key reports its state on the home page as it changes.
Paging, alarm and control
More than a dial tone.
-
Three SIP accounts
Three independent registrations, each with a primary and backup server, session timer, SRTP option and PCMU / PCMA / G722 / G729 codecs.
-
Marking (打点)
Hold a function key and up to eight target phones loop a marking tone; release to stop. A lease timeout stops it if the network breaks.
-
Local broadcast
Upload a WAV, choose the trigger and play it through the phone amplifier. An optional dial number, relay and alarm light can fire with it.
-
Manual alarm
Trigger a stored alarm WAV over multicast or UDP broadcast. Phones with the same ID play their own copy, so a weak Wi-Fi AP does not block it.
-
Multicast
Send live audio to a multicast group for site-wide paging. The status page shows when the channel is active and which group is in use.
-
10+ functions per key
Each function key can dial, hotline, mark, multicast, start a local broadcast, fire a relay, raise an alarm, speed-dial, answer or hang up.
-
Live I/O status
The home page shows each input, relay, LED and button state as it changes. Outputs can follow ringing, calls, alarms or multicast.
-
USB headset
USB headset support with separate microphone gain and volume, alongside handset and hands-free gain settings and selectable ring tones.
-
Network and service
VLAN, LLDP, SNMP, NTP, Modbus, OpenVPN, ONVIF / RTSP, action URLs, SIP PnP, config backup, logs and packet capture.
-
Direct IP calling
Call another phone by IP address with no PBX, registrar or server in between — useful for two-point links, temporary sites and simple gate, lift or desk pairs.
Where it works
When the weather is part of the job.
Tunnels, docks, car parks and outdoor process areas leave equipment exposed to rain, spray and temperature swings. These models are built around sealed enclosures and protected connections, so the call path stays available when conditions turn.
- Sealed enclosures for wet sites
- Armored handset and cord
- Wall, pole or freestanding mounting
