3 nstallation and peration Manual The ntelligent Solution 1 General These two kinds of conventional fire alarm control panel are multi-wire control panels developed from microprocessor on EN GST104 Conventional Alarm Control Panel (hereinafter called GST104 control panel) can monitor 4 zones. GST102 Conventional Alarm Control Panel (hereinafter called GST102 control panel) can monitor 2 zones. Those with signal output interface board has a passive normally open alarm output contact and fault output contact for each zone. Each zone can be connected with 15 conventional fire detectors. They can connect with C-9403 conventional sounder strobe on EN 54-3, C-9103 conventional heat detector on EN 54-5, C-9102 conventional smoke detector on EN 54-7, and C-9202 manual call point on EN They have two external control output points to control some devices such as sounder strobe and sounder etc. The stated maximum load is two sounder outputs. They are designed with internal standby batteries and space for installation (two sealed acid storage batteries). They have functions of test and isolation, setting day/night mode, indication of normal state, fault state, alarm state, alarm of short circuit and open circuit of external connections and identifying the location of the detecting zone. The installation and operation of the two kinds of panel are very simple and convenient. All the control functions can be realized through a key switch, and the programming function can be realized through a key switch and an internal switch. Except for two monitoring zones (two zone input) less, two passive normally open alarm output contacts and two passive normally open fault output contacts less for those with signal output interface board, and some minor differences in appearance and structure, GST102 control panel is the same as GST104 control panel in technical specifications, usage and operation. We will take GST104 control panel as the example. 2 Technical Specifications 2.1 perating Voltage 24VDC 15% or 230VAC 50Hz Fuse: 2A delayed Wiring: Adopt shielding wire with diameter not less than 1.5mm, complying with local code when installing. 2.2 Standby Batteries The capacity of the standby batteries is outfitted according to the user s demand computed with reference to Section 4.8.

Check relay K7 of the main board and its peripheral circuit. No fault reporting of main power and Check N6 of the main board and its standby battery peripheral circuit. Wrong judgment of zone state or output Wrong alarms of many zones: checking state Measure the voltage at VREF_H of the main board normal or not. t can be figured out according to the power voltage +24V (really measured) and resistor R67 and R60. Normally, when the power voltage is +27V, the voltage here is 3.65V. Wrong alarming of fault of many zones: Measure the voltage of VREF_L of the main board normal or not. t can be figured out according to the power voltage +24V (really measured) and resistor R68 and R61. Normally, when the power voltage is 27V, the voltage here is 1.0V. Measure the voltage at VREF_S of the main board normal or not. t can be figured out according to the power voltage +24V (really measured) and resistor R58 and R6. Normally, when the power voltage is 27V, the voltage here is 24.7V. Wrong alarming of fault of many output circuits: Measure the voltage of VREF_H of the main board normal or not. Check the setting of contact pin X1 X2 right or not and the fuse F2 F3 be placed right or not. Not saving the result of setting D9 (24LC02) on the display board is damaged.
