DCS has 8 dry-contact outputs that can be used to activate external devices. For example, DCS can connect with the volume controller via one of these outputs to conduct force cut-off function. It has 8 pairs of audio output where each one allows multiple 100V loudspeakers to be connected in parallel. A record output port is dedicated for external recording device.
DCS also has 8 dry-contact inputs that can be linked with a fire alarm control center which supports broadcasting alarm tones and evacuation announcement when fire happens. On the rear panel, there are 1 network audio input and 4 auxiliary inputs, which provide connections to external audio sources such as CD/DVD, cassette, FM tuner etc. In addition, there are 4 audio inputs that are capable to adjust volume automatically according to ambient noise (when HN D32N Noise Detector is installed). Users can set the phantom power and input gain of each volume control input on the rear panel.
DCS can connect with devices and the network to extend zone connections via 4 interchangeable 10M/100M adaptable Ethernet interfaces.
SAFETY AND ROBUSTNESS
DCS can detect errors on main power supply, backup power supply, amplifier circuit, amplifier protection, software, communications, and loudspeakers circuits in runtime. By locating the error’s occurrence, DCS provides valuable information for repairing or replacing the malfunctioned devices.
DCS supports power supply and amplifier redundancy. Built-in fuse provides over-current protection to the main power supply. When a shortcircuit error is detected in DCS, the power supplied from main power will be cut off and switched to the backup one. Same technology is also used in amplifier switchover. User can configure the amplifier backup solution as 3 backup for 1 main, 2 backup for 1 main, 1 backup for 1 main or 2 backup for 2 main.
DCS is built with a 1GB flash memory. Via X-618 Config software, users can upload audio files for later playback or audio synthesis. DCS can automatically write work log and fault log and store up to 10,000 entries for each.
DCS supports a variable range of audio sources, such as audio files from external devices (CD/DVD, cassette, FM tuner and etc.), remote paging announcement or broadcasting from X-NPMI, announcements from the PTT emergency microphone etc.
DCS can broadcast 4 audio message or internet audio simultaneously. Timer broadcast setting can be configured via software to allow system to play specific programs at a specific time even when it is not supervised. With the software, user can also handle up to 255 priorities to meet complex public address requirements.
User can select audio sources and zones to broadcast by clicking directly on the control buttons on the front panel.
DCS supports audio matrix, allowing any audio sources to be played in any zones.
DCS has a built-in loudspeaker and it can enable zone and audio source monitoring. When the system has been extended via Ethernet, network remote supervision can be performed.
A highlight of DCS is the one-click emergency mode switchover feature. A red emergency mode button can be found on the front panel, which can activate the fire alarm broadcast mode in an emergency by a single click. In emergency mode, the recorded evacuation announcement will be broadcasted and the zone alarm indicator lights will be turned on. This function significantly improves the evacuation efficiency.
Users can preset the functions for the other buttons or their combo usage. The label describing buttons’ functions can be replaced easily.
