Specifications

Model UV-810
Points of Indicator Up to 15 point
(line up: 3/6/9/12/15 point type)
Alarm Accuracy As per gas detector:
– Combustible gas: within 25% of alarm value under an identical condition
– Toxic gas: within 30% of alarm value under an identical condition
Alarm Indication
Alarm Sound		 Indicator unit
– Alarm lamp: blnks on alarm, lights up by reset, latching (or non-latching)
Alarm unit
– Trouble lamp:
red lamp lights up (1st stage, 2nd stage) when at least one indicator unit is activated
yellow lamp lights up when at least one indicator unit cause a malfunction
External Output Terminal for collective alarm
– 2nd alarm contact: 1a non-voltage (STD) (100 VAC, 1A. 24 VDC, 1A load resistance)
– 1st alarm contact: 1a non-voltage (STD) (100 VAC, 1A. 24 VDC, 1A load resistance)
– Buzzer contact: 1a non-voltage (STD) (100 VAC, 1A. 24 VDC, 1A load resistance)
– Trouble contact: 1a non-voltage (STD) (100 VAC, 1A. 24 VDC, 1A load resistance)
*Collective alarm contacts of 1st alarm and 2nd alarm can be changed to 1b contact (need to specify)
Terminal for individual alarm
– 2nd alarm contact: 1a non-voltage (STD) (250 VAC, 2A. 24 VDC, 2A load resistance)
– 1st alarm contact: 1a non-voltage (STD) (250 VAC, 2A. 24 VDC, 2A load resistance)
Analog output
– Gas concentration analog output signal: 4-20 mA, selectable from 1-5 V (need to specify)
Power Source AC specification: 100-240 VAC ±10%
DC specification: 24 VDC ±10% (need to specify)
Power Consumption AC input: 100-240 V, Pump power supply: 24 VDC
– Power consumption (VA) = (V3 x points of indicator + VAS) x 1.25 (SW power loss)
DC input (24 V ±10%), Pump power supply: 24 VDC
– Power consumption (W) = (V3 x points of indicator + VAS)
**V3 includes power consumption of gas detector
Operating Temperature/
Humidity		 -10 to +40 °C (excluding rapid temperature change)
10 to 90 %RH (excluding rapid temperature change, non-condensing)

*Only on models with a build-in backup power supply (option)
