Installation and Operation Manual

Page 3

Chapter 1 Product Introduction

GST200-2 Intelligent Fire Alarm Control Panel (FACP) is designed to comply with EN

54-2 standard with qualities of simple installation, operation, and easy maintenance. It is

used in fire alarm system with the following features:



It controls at most 30 zones. Each zone has its own alarm and fault/disable LEDs

and a label.



Maximum two Class A loops. The first loop can have up to 235 addressable

devices, and the second up to 242 devices. It is compatible with a series of

addressable GST products, which are intelligent sounder strobe (I-9403) complying

with EN 54-3, rate of rise and fixed temperature heat detector (I-9103) complying

with EN 54-5, photoelectric smoke detector (I-9102) complying with EN 54-7,

intelligent manual call point (I-9202) complying with EN 54-11, intelligent reflective

beam detector (I-9105R) complying with EN 54-12, input and output module

(I-9300, I-9301) complying with EN 54-18, and loop isolator (C-9503) complying

with EN 54-17.



The LCD can display 8 lines in total and 18 characters each line, assisting the 15

LEDs in displaying important information.



The memory does not lose data even if power supply is accidentally removed.



It has manual keys for each zone, which can activate/silence the sounder strobes

separately.



Automatically prompting operation steps for every alarm device and for smoke

exhaust and fire extinguishing equipment by field programming.



Sounder strobe interface provides 0.5A/24V output, compatible with GST

conventional sounder strobe (C-9403) designed according to EN 54-3.



RS232 interface enables communication with PC.



RS485 interface enables networking.
