Product Introduction

The manual fire alarm button is a hand alarm with two buses and a telephone function. It has the characteristics of stable performance and high reliability. After manually pressing the operation panel, the manual can feed back the on-site fire alarm signal to the controller, so as to achieve the purpose of alarm, and can be used with the phone handle at the same time. Through linkage programming, linkage equipment such as sound and light alarms can be started at the same time.

Features

Stable performance.

Adopt SMT surface mount technology, high reliability and good consistency.

Adopt two-bus system, no polarity requirements, while ensuring low power consumption, the transmission distance can reach up to 1500m.

Electronic encoding method, can be addressed by a dedicated electronic encoder.

With preemption function, the fastest alarm speed is ≤1S.

After the alarm, you need to use the matching special key to reset.

It adopts split structure, which is easy for customers to install, construct and maintain, and has a thin design.

The telephone jack is located at the bottom, and a logo guide is added on the front of the button for easy identification.

Scope of application

Manual fire alarm buttons are used together with JBF series detectors in two-bus fire alarm systems, and can be used with JBF series controllers.

Applicable to hotel rooms, office buildings, libraries, theaters, postal buildings and other buildings.

Working principle

The manual fire alarm button is composed of a start switch and corresponding processing circuit. When there is a fire alarm, press the button manually, the button switch is closed, and the alarm signal is transmitted to the controller through the loop bus. At the same time, the fire alarm indicator of the manual fire alarm button is controlled by the inspection The blinking of the status becomes steady to show the alarm status. The telephone light on the handbook will flash when connected to the telephone system.
