Industrial & Outdoor Telephones (Weatherproof, Vandal Resistant & ATEX)

Four decisions narrow the range quickly: how the phone connects, how well sealed it needs to be, how people will use it, and whether the area is hazardous.

Analogue phones connect to a standard phone line, an analogue PBX extension or an FXS port, and take their power from the line. The analogue Project Telecom and ATL Delta models also have lightning and transient protection to ITU-T K.21.

SIP phones connect to your network over Ethernet and register with an IP phone system or hosted VoIP service. The Gai-Tronics, ATL Delta 9000S and Project Telecom SIP models take Power over Ethernet, so one cable carries data and power. Your VoIP provider will need to provision the phone on its platform.

4G phones use a Micro SIM and need no phone line or network cable, which suits remote compounds, temporary sites and car parks without cabling. The Project Telecom 4G versions need a 7.4V to 12V DC supply and can be programmed and report their status by SMS.
The UK's analogue PSTN network is being switched off, with the deadline set for January 2027.

*Analogue outdoor phones still work after the switch-off when connected to an analogue port on a phone system or through an analogue telephone adapter (ATA). If you are replacing phones on copper lines now, a SIP or 4G model avoids the adapter.

IP ratings are set by EN 60529. Both IP65 and IP66 phones are fully sealed against dust. IP65 protects against water jets, IP66 against powerful water jets, and IP67 against temporary immersion.

The Gai-Tronics Commander is rated IP65. The Gai-Tronics Titan is IP65 with its door open and IP66 with it closed. The ATL Delta 9000 range is IP66, and Project Telecom phones are IP66 with IP67 versions available on request.

A handset phone suits noisy areas, where holding the receiver to your ear helps. Most models here have a stainless steel armoured cord, which is much harder to cut or pull out than a curly cord.

Handsfree push-to-call phones have no handset to damage or steal. The caller presses a button and speaks, which suits help points and public areas.

Lift-to-call (hotline) phones have no buttons at all. Lifting the handset dials a stored number, so nobody can call anywhere else. Examples are the ATL Delta 9000-TNK, the Project Telecom PT101-CB and the Gai-Tronics Titan 0 Button.

A door gives the keypad and handset extra protection and keeps the phone out of sight, which discourages misuse. An open front lets people reach the phone straight away, which matters at emergency and help points. Most ranges come in both styles, for example the Project Telecom PT101-FK (door) and PT103-FK (open front).

Phones in areas classified for explosive gas or dust must be certified for that zone. See our ATEX & hazardous area telephones.

An inductive coupler lets hearing aid users hear the caller through their aid's T setting. It is fitted as standard on the Gai-Tronics Titan and Commander and on the Project Telecom PT101-FK, PT103-FK and PT101-CB. The ATL Delta range has a hearing aid compatible receiver. On the Project Telecom push-to-call models it is an option at extra cost.
