Quick Details Brand Name: DATAKOM Model Number: DSD-050 Operating Temperature: -20 to 70 °C (-4 to +158... Dimensions: 232 x 200 x 65 mm (W x H x D) Availability: On stock Specifications DATAKOM DSD-050 is a high-tech unit which detects seismic motion. DESCRIPTION DATAKOM DSD-050, from C4G Solutions Company, is a high-tech unit which detects seismic motion. On the occurrence of an earthquake it gives audible and visible alarms and closes a relay contact to shutdown gas and industrial valves. Thus it is possible to minimize the fire risk after an earthquake. DSD-050 is a very cost effective device for shutdown applications. The unit is based on highly reliable dual axis seismic sensors. It is small, maintenance free and capable of performing self-test. The unit operates on mains power. It incorporates a lead-acid battery and an automatic battery charger which allow uninterrupted operation even in case of AC power failures. During long mains failures, if the internal battery gets weak, the unit gives audible and visible alarms. The seismic properties of the unit are conformal to ANSI Z.21-70(1981), ASCE 25-97 and TS 12884 standards. DISPLAYS OPERATIONAL (yellow) : It turns on continuously for 6 seconds after power-up or reset. It flashes while the unit is operational. EARTHQUAKE (red) : It turns on when the unit detects a strong motion. CABLE BROKEN (red) : It turns on when the unit detects the rupture of the solenoid cable. BATTERY LOW (red) :It turns on if the battery voltage falls below the Battery Low Warning Limit. SELF TEST The unit performs self test at power_on or reset. During the self test, the OPERATIONAL led turns on steadily. The self test consists on the application of an external acceleration signal to the sensors and checking back the detection. If the unit passes self test, the OPERATIONAL led starts to flash normally. If the self test fails, all leds flash, the audible alarm is activated and the relay output is energized. INSTALLATION The unit is designed for vertical mounting. Thus the sensors will be placed in the horizontal plane as requested by the standards. The unit has an indoor type panel. Do not install the unit outdoor or at highly humid or warm environments. The solenoid valve used should have a 12 V-DC coil. Please contact DATAKOM for the list of compatible solenoids. The solenoid cable should not exceed 12 metres with 2x1mm2 cable and 20 metres with 2x1.5mm cable. Energize the unit only after the installation is complete. When the OPERATIONAL led is flashing, press the TEST key in order to check valve operation. WARNINGS After installation, the OPERATIONAL led should be flashing. No red light should be visible on the unit. However if the battery is discharged, the BATTERY LOW led may turn on for a few minutes. Please reset the unit in this case. If the led turns off, this is not a failure. If the EARTHQUAKE led turns on at power-on, please reset the unit. It will turn off.
