Refrigerated warehouses and cold storage facilities
Freezer rooms and cooler areas
Industrial warehouses and logistics centers
Construction sites
Transportation terminals
Railways and tunnels

Outdoor and Cold-Environment
How It Works
The LCHS-01-S works as a network-connected SIP paging speaker. It can be connected to a compatible SIP server, IP-PBX, SIP phone system, IP paging microphone, management software, or multicast paging system. Users can make announcements from:
SIP desk phones
IP paging microphones
Compatible management software
Existing VoIP / IP-PBX systems Security or control room workstations, depending on system design
The speaker can be configured for individual paging, zone paging, group paging, or all-call announcements depending on the network and SIP system configuration.
Power and Network Connection
The LCHS-01-S uses a standard RJ45 Ethernet connection and supports Power over Ethernet.
Power: PoE IEEE 802.3af / 802.3at
Network: RJ45 10BASE-T / 100BASE-TX
Audio Streaming: One-way
Installation:
One Ethernet cable can provide both network communication and power when connected to a compatible PoE / PoE+ switch or PoE injector If the existing network does not provide PoE, a PoE injector or PoE switch can be added to power the speaker.
Installation & Mounting
The LCHS-01-S can be mounted on a wall, pole, structural column, ceiling structure, bracket, or other suitable surface depending on the site layout. For best performance, the speaker should be installed where the horn is aimed toward the intended coverage area.
In large warehouses, outdoor yards, docks, refrigerated storage areas, or high-noise locations, multiple speakers may be required for proper coverage.
Final speaker quantity and placement should be confirmed based on:
Area size Ceiling height Noise level Racking layout Wall and door locations Outdoor exposure Required paging zones Network cable availability PoE switch location and power budget
