FCPS-45B/20A quotation information 1、 Product Overview

FCPSIt is a fire protection product developed to meet the needs of modern fire protection systems after special improvements have been made on the basis of the basic model. The product does not trip when the protected circuit fails (except for short circuits), but only provides a pair of passive fire alarm contacts for users to choose to install alarm devices or other devices (such as intermediate relays).

FCPS-45B/20A quotation information2、 Product features and parameters

The fire control and protection switchgear adopts a new design concept, with the fire control controller and other modules to achieve the function of 'no tripping in case of faults'.

FCPSThe fire control and protection switch is a multifunctional fire protection device that integrates the functions of low-voltage electrical products such as fuses, circuit breakers, contactors, starters, isolators, thermal relays, overload (or overcurrent, phase failure) protection relays, motor comprehensive protectors, intelligent residual current circuit breakers (relays), etc. It has the characteristics of remote control and local control, automatic and manual control, panel indication, fault inquiry, and flexible setting; Its maximum rated current is 12, with a maximum breaking capacity of 80KA, meeting the specific requirements of 'only alarm and not trip' during overload and overcurrent in the fire protection system, and 'both alarm and trip' during short circuit.

3、 Product Usage

FCPSFire type control and protection switchgear is mainly used in fire protection systems with AC 50Hz (60Hz), rated voltage up to 690V, and rated current up to 0.4 to 12. It can connect and carry current under normal conditions, including specified overload and overcurrent conditions, to achieve 'only alarm without tripping', and can connect, carry and disconnect current under abnormal conditions (such as short-circuit current), achieving the function of 'both alarm and trip'.

5、 Application Description

Sudden power outages during actual operation will result in greater motor loads than overload losses, and overload protection should not be installed. These loads include fire hydrant pumps, sprinkler pumps, smoke exhaust fans, etc. If overload and other protective devices are installed, when a fire occurs, the overload and other protective devices will cause the product to operate within the set time, and the fire-fighting equipment will not be able to operate normally, delaying the timing of fire extinguishing, and the losses may be even more severe. If overload protection devices are not installed, the fault will expand and cause irreversible losses. So KBKF is equipped with overload protection function devices. Through a special linkage mechanism, when a fire occurs, overload and other protection functions act on passive alarm signal contacts within a set time, reminding the fire control room duty personnel to inspect and reduce the fault until it is eliminated.

FCPSThe fire control and protection switch electrical appliances are equipped with digital fire controllers and other functional modules to achieve the function of only alarming and not tripping in case of faults. When the protected circuit experiences overload or overcurrent (except for short circuit faults),SKB-At the same time as the fault code is displayed on the panel of the F fire type control and protection switch, a pair of passive fire alarm contacts 95 and 98 (basic type is passive overload alarm contact) are closed for output.

6、 Precautions

During normal operation, the knobs on the panel can be used to directly control the connection and disconnection of the main circuit on site.

When faults such as overload, overcurrent, phase loss, three-phase imbalance, etc. occur, the 95 and 98 passive fire alarm contacts close, connecting external alarms or other devices to remind the duty personnel to repair the faulty circuit. The KBKF product operating mechanism knob remains in the closed position and does not trip, and the main circuit continues to open. At this time, the main circuit can be disconnected by the external stop button or the knob on the panel. After the fault is eliminated, it must be re pressed or reset.

3.FCPSWhen a short circuit occurs in the product, the 05 and 08 contacts emit an alarm signal, the operating mechanism is in the tripped position, and the main circuit is disconnected. After troubleshooting the short circuit, it must be reconnected or reset.

4. Special reminder; When a fault occurs in the circuit of a fire protection product, the passive contacts 95 and 98 of the fire protection system will close, connecting the external alarm circuit. To release the alarm signal, the knob must be turned to the disconnected position or the power should be cut off through an external stop button. To continue using, it should be turned back to the connected position.
