Please refer to your detector manual for important information regarding coverage, location and positioning including areas and conditions to avoid. -
Page 5: Circuit Board Connections Overview
100-240V~ Mains Power should be supplied to the [POWER / LINE IN] terminal and fused at 3A. On connecting the mains supply to the panel, the red power LED indicator will light up – this is located on the front cover (OGS Logo). GAS VALVE OUTPUT 100-240VAC electrical power supplied from the [VALVE OUT] connector using a 3-core cable can be connected to a gas solenoid valve which can shut the gas supply on alarm status. - Page 6 Installation & Operation Manual Merlin 1000V+ PRESSURE SENSOR Pressure sensors should be screwed to the downstream port of the valve. Pressure Sensors are tested and certified to AS 4628/2005. The pressure sensor is wired to the [PRESSURE SENSOR] connector and screwed into the downstream port of the gas solenoid valve.
