Factory Background Broadcast and Fire Protection Broadcast System Design PlanProject overview
The area of the factory is about 26000 which is divided into six parts:
The fist workshop building;
The second workshop building;
Dormitory and canteen;
Outdoor walkway.User requirements
Multiple sound source are available for selecting to broadcast;
Timing broadcast and timing chime are available to inform the time of work or off work;
Zone broadcast and zone paging are available;
Fire emergency broadcast are available in the case of emergency. System Configuring and Design Project
DSPPA Public Address System apply the world's most advanced technology of circuit and system design, combine the function of background music and fire emergency broadcast and can realize the function switching automatically. There are many different equipments, components available for selection. The functional configuration is practical and flexible.
1. Pre-amplifier is MP9811, it has 5 microphone inputs, 2 line inputs, 2 fire emergency inputs. The volume of every input channel can be adjusted separately and one tone controlling for all input channels.
2. MP9813 is used for signal distributor and can distribute the source signal to different zones. Every zone can be opened and closed separately. In the case of an emergency, the zones will switch to emergency broadcast status automatically.
3. Use MP9810P and MP9810R(paging microphone) as zone paging device. The advantage of the device is that it does not affect other zone broadcasting when the designated zones are paged.
4. Constant voltage output amplifier(MP3500(1500W) P2500(650W)) with 100V and 70V output terminals are used as power amplifiers. The amplifier has sufficient power for output and has link interface for easy linking. The amplifier also has protection measures for output short-circuit and over-heat warning and distortion warning functions.
5. The sound sources adopt five-disk player and digital tuner.
6. The loudspeakers adopt all-weather column speaker DSP408, grassplot speaker DSP3601 and DSP630. They are beautiful in appearance, elegant in sound and easy in installation.
7. Other peripheral devices: the microphone adopts handhold paging microphone CB100, the main power supply device adopts power sequence controller MP9823 for assembling all device main power and delay turning on-or-off device main power automatically and orderly. All devices are installed in one professional rack and ensure the whole set of devices look elegant in appearance and durable in quality.Device List:
