LK-GSP4 Gas Detection System

The Landon Kingsway Gas Detection System GSP4 can be used in many applications such as factories, car parks, shopping centres and most commonly boilerhouses. The GSP4 can be used with up to fourgas detectors, wiring back to the control panel using four wire low voltage cable.

A variety of remote detectors are compatible with the GSP4 Natural Gas, Carbon Monoxide or LPG being the most commonly used. These detectors can be used in any combination. Fusible links can also be used, when wired in series multiple fusible links can be used on the same terminal.

Basic Operation
When the remote sensor or sensors detect the presence of the target gas, a signal will be sent back to the panel, the panel then sends a signal to close the gas solenoid valve shutting off the gas supply. The panel will then indicate which zone is in alarm. Once the problem has been rectied the reset button is pressed and the panel should indicate zone on. If there is still gas present in the area (zone) the panel will go into alarm once again.

The Natural Gas Detector and LPG detector will go into alarm at 10% of the low explosion level (LEL). The Carbon Monoxide will go into alarm when the level has reached 50ppm for over 4 minutes.

The fusible links are rated at 72°C, which is when the temperature in the zone goes above the rated temperature the system will go into alarm shutting off the gas supply. When the system goes into alarm the LED indication on the panel lights up and an audible alarm sounds. There are also relay outputs for a BMS system and additional auxiliary equipment such as a ashing beacon.
