METROPLEX CO.,LTD.

- Two Stage Accumulation Function Circuit detection requires a period of accumulation time to reset the detector, and detection of the second stage of accumulation, thus reducing the chances of a false alarm caused by interference from ordinary circuits, and improving the dependability of the Central Control Unit. - Stand-by Battery Protection System During blackout, if the stand-by battery has discharged to below DC18V, it will automatically stop discharging, thus increasing battery life. - Quality Control The control panel switches and all of the base board components of this unit are all certified by CNS and CE. All units must pass stringent quality inspections before leaving the factory, ensuring that each will be performing as expected. - User-friendly Design All circuit boards use a modular design; the external lines are also separated from the terminal circuit board, with protections implemented on the input end. If a faulty power supply is connected to the circuit board caused fault, only the affected circuit board needs to be exchanged without disconnecting the external lines, thus greatly improving maintenance and inspection efficiency. - Exterior Design: This unit's circuit display uses high-end heat-resistant plastic, making its stream-lined exterior poised and elegant. With the circuits accessorized with indication plates, it makes all information regarding the buildings, floors and circuit properties clear at a glance. - Other Application: This Central Control can also be collocated into a 3-in-1 system with our Broadcast Host and Emergency Telephone Unit, creating a system that both looks and performs like a unity, and enhance the beauty of in-site use.

This Fire Manual Station can quickly transmit a signal to the fire receiver terminals or the repeaters while the button under a transparent protective cover has been pushed at the first finding of a fire accident. (This signal is beyond the accumulated time limitation.) There is a light over the button. The light will light up as a signal has been exactly received by the receiver terminal. There is also a telephone jack for telephone communication with attendant at the fire receiver terminal

The fire alarm bell is an equipment controlled by the fire receiver terminal or the repeater and sounds a warning as a fire accident occurred.

The rate-of-rise heat detector is designed to sense the rapid or abnormal temperature rising. If ambient temperature rises rapidly, the air in chamber expands and pressed the metal sheet to connect the contact point and give advance warning. When a slower temperature change occurs, the expanded air escapes through a hole to keep the pressure balance so that the fault alarm never occurs.

Adopting photoelectric sensing principle, when fire break out and smoke enters the light-tight chamber of detector then the smoke particles cause the infrared light reflex. As receiving unit receive certain extent of emitting light, the fire alarm will be activated. The due-colored LEDs are built in the main body in order to easily identify the status of the detector. Green light blinks every 15 seconds to indicate the detector is working normally and red light lights up continuously to indicate fire alarm activated.
