Our NOMS compliant series 9 intercom system is specially developed for use in tough custodial environments. Most units have stainless steel faceplates, flush mount back boxes and ANTI‑TAMPER fixings, ideal for Police, MoJ, HM Prison Service, secure hospitals and similar establishments. Many units also benefit from safer cell compatible ANTI‑LIGATURE design making the system suitable for custody suites, seclusion rooms etc. For more extreme locations we also offer units with super‑flush back boxes for mounting in ANTI‑PICK adhesive.

Our 970.51 is a vandal resistant, stainless steel, push‑to‑talk, series 9 intercom master station, with lock release feature.

Push‑to‑talk enables the operator to control the audio direction, reducing the possibility of operators being accidentally overheard and preventing the user from overriding the conversation.

The additonal lock release button enables the operator to control access.

The speaker and microphone volume are adjustable to suit the operating environment with a maximum output of 80 dB.

The standard unit is annotated in black with the words TALK/LISTEN, CALL/CANCEL and LOCK RELEASE. Alternative annotation is available on request.
