Detector A1R thermovelocimeter TV 65 Apollo
The Thermovelocimetric detector of the series 65 monitoring the temperature using a dual thermistor network which provides an output voltage proportional to the temperature of the outside air.
exist 12 Thermovelocimetric detectors in the series 65 designed to meet a wide range of operating conditions.
Operation
The detector has a molded self-extinguishing polycarbonate white box. The contacts of stainless steel cleaner nickel connect the detector to the base. Under the Hood, a printed circuit board contains electronic components for signal processing.
A corresponding pair of thermistors with negative temperature coefficients are mounted on the printed circuit board so that a thermistor is exposed to provide good thermal contact with the surrounding air while the other thermistor is thermally insulated.
Under stable conditions, both temperature sensors are in thermal equilibrium and have the same resistance value. If the air temperature rapidly increase, the exposed thermistor resistance becomes smaller than the isolated thermistor. The proportion of the resistance of the thermistors is electronically monitored and an alarm is initiated if the ratio exceeds a preset level factory. This feature determines the ‘rate of increase’ do detector.
If the air temperature slowly increase, no significant difference in resistance develops between the thermistors, but at high temperatures, a fixed-value resistor connected in series with the thermistor becomes significant isolated.
When the sum of the insulated thermistor and fixed resistor resistance compared to the resistance of the exposed thermistor reaches a preset value, an alarm is initiated. The value of the fixed resistor is selected to place the detector in alarm state at a specified fixed temperature.
The detector signals an alarm condition by activating an alarm latch, increasing the current drawn from the source of about 50μA to a maximum of about 75mA. This drop in impedance detector is recognized by the control panel as an alarm signal.
The alarm current also illuminates the full LED detector. A remote indicator connected between the terminal IN and terminal L1 will -R a voltage to power supply least 1 volts through it and so will light.
To ensure proper operation of the detector, the control panel should be organized to provide maximum 33 volts DC and at least 9 DC volts in normal operation. The power may fall 6 volts DC in alarm conditions if at least 10mA of supply current is available in this tension. To ensure effective illumination of the integral LED and any remote indicator, the detector power must exceed 12 volts.
To restore the detector to the rest condition, he
it is necessary to restore a normal temperature level and interrupt the electrical supply to the detector for at least one second.
