Project Telecom PT101-CB Autodial Outdoor Phone

The Project Telecom PT101-CB Autodial Outdoor Phone is a heavy-duty industrial communications solution designed for locations where rapid access to reliable voice communications is essential.

Featuring simple lift-to-call autodial operation, the PT101-CB allows users to immediately connect with a pre-programmed contact simply by lifting the handset, making it ideal for emergency help points, transport infrastructure, public-access locations and industrial facilities. Available with Analogue, SIP or GSM / 4G connectivity, the PT101-CB can be integrated into traditional telephone systems, modern IP networks or mobile communications infrastructure, providing a flexible solution for a wide range of applications.

Featuring a rugged non-corrosive cast aluminium enclosure, weatherproof protective door, vandal-resistant construction and IP66-rated weather protection as standard, this heavy-duty telephone is engineered to deliver dependable communications in demanding industrial and outdoor environments. Available in Yellow, Blue, Red and Grey finishes, the PT101-CB can be selected to suit site visibility requirements, safety standards or installation preferences.

Ideal for factories, warehouses, manufacturing facilities, transport hubs, utility sites, ports, marine environments, tunnels, car parks, security installations, construction projects and public assistance points, the PT101-CB combines exceptional durability with flexible connectivity options, making it well suited to critical communications and infrastructure applications.

Designed for Demanding Environments

The PT101-CB has been specifically engineered for locations where conventional telephones may be exposed to harsh weather, dust, moisture, impacts or vandalism. Manufactured from corrosion-resistant die-cast aluminium, the telephone provides outstanding protection and long-term performance in challenging industrial and outdoor environments.

Its IP66-rated enclosure protects against dust ingress and water exposure, making it ideal for exposed outdoor installations. The weatherproof protective door provides additional environmental protection whilst allowing rapid access to communications when required.

Whether deployed in manufacturing plants, warehouses, rail networks, ports, tunnels, utility facilities, construction sites, transport infrastructure or public access areas, the PT101-CB is built to provide reliable communications where performance and durability cannot be compromised.

Its vandal-resistant construction, armoured handset cord and heavy-duty components make it particularly suitable for public-facing environments, remote locations and critical infrastructure applications where equipment must continue operating despite heavy daily use, accidental damage or deliberate abuse.

Simple Autodial Operation & User-Friendly Design

The PT101-CB has been designed for simple and intuitive operation in demanding environments. Unlike conventional telephones requiring manual dialling, the PT101-CB automatically initiates a call to a pre-programmed destination when the handset is lifted.

This lift-to-call operation enables immediate communication with security personnel, control rooms, help desks, emergency services or site management teams, helping to reduce response times and simplify user operation.

An integrated inductive coupler is fitted as standard to improve accessibility for hearing aid users, while the high-output warble ringer ensures incoming calls can be clearly heard in noisy industrial and outdoor environments.

Built for Long-Term Reliability

Designed for continuous operation in harsh conditions, the PT101-CB combines a corrosion-resistant cast aluminium housing, weatherproof door and stainless-steel armoured handset cord to withstand years of demanding use.

With a calculated MTBF exceeding 50,000 hours, the PT101-CB is engineered to minimise maintenance requirements, maximise system availability and provide dependable communications in mission-critical applications.

The telephone incorporates a magnetic hook switch with no visible moving parts, helping to further improve reliability whilst reducing wear and maintenance requirements.

Flexible Connectivity Options

The PT101-CB is available in three connectivity variants, allowing it to integrate into virtually any communications infrastructure.

Analogue Version

The analogue version connects directly to standard analogue telephone lines, including PSTN and PABX systems. Powered directly from the telephone line, it provides a simple and reliable communication solution for sites utilising traditional telephony infrastructure.

The analogue model supports remote configuration via DTMF programming and provides both lift-to-call autodial functionality and inbound call capability.

SIP Version

The SIP version connects directly to SIP telephone systems, IP-PBX platforms and VoIP networks via standard RJ45 Ethernet connections. Supporting SIP 2.0, dual SIP servers, PoE (Power over Ethernet) and web-based configuration, it provides a flexible and scalable communication solution for modern IP telephony environments.

The SIP model supports G.711A/u, G.722, G.723.1, G.726 and G.729 codecs, echo cancellation, VLAN support, DHCP, PPPoE and STUN, delivering enterprise-grade communication performance.

GSM / 4G Mobile Network Version

The GSM / 4G version communicates via GSM and 4G mobile networks using a Micro SIM card, providing a flexible communication solution where fixed telephone lines or IP networks are unavailable.

Supporting LTE FDD, LTE TDD, WCDMA and GSM frequency bands, the telephone can be remotely configured via SMS messaging and supports remote status reporting for simplified management of deployed units.

This version is particularly suitable for remote infrastructure, utility sites, transport networks, construction projects and temporary installations.

Available In Four Colours

The PT101-CB is available in Yellow, Blue, Red and Grey finishes, allowing the telephone to be selected to suit site requirements, visibility needs and installation environments.
