Chapter 7 Setting up the NX-534E
Overview
The NX-534E listen-in module is a two-way audio and voice communicator for the NX-10 control
panel. Once the control panel has communicated an alarm, the NX-534E listen-in module allows a
monitoring service operator to listen-in to a customer’s premises. It can also provide basic two-way
voice communication. This procedure is controlled from the central station by the use of a touch tone
telephone.
