Specifications:

1. power requirements:

• a. input voltage-+11to +15VDC

• b. input current-

  • i. Standby-200 ma DC max

  • ii. Operating-4amps DC peak

2. Operating temperature: -29F to +158F

3. Alarm Outputs: The Sigalarm provides alarm outputs in 3 forms simultaneously

• a. Visual-by means of a flashing red light mounted on the control module.

  • i. Repetition rate: Proportional to electric field intensity at the sensor cable, up to a maximum of 5 alarms/second

• b. Audible-internal buzzer

• c. Audible-external horn

  • i. Repetition rate: Proportional to electric field intensity at the sensor cable, up to a maximum of 5 alarms/second

4. Sensing: Electric field, 60Hz or overseas 50Hz

5. Sensitivity adjustment: Front panel controls provide means for coarse and fine adjustment of the SIGALARM sensitivity. The coarse control adjusts the sensitivity by 1.0.10, 100, 1000, 10,000, and 100,000. The fine control adjusts the sensitivity within each range set by the coarse control, providing a means of continuous adjustment of sensitivity from zero to the maximum sensitivity set by the coarse control.

6. Size 8” X 7.55” X 4” 7. Range of effectiveness: Depending upon the proximity of the overhead high voltage line, and its intensity, SIGALARM can be adjusted to actuate the warning alarm at any desired distance from (OSHA minimum) to several hundred feet.
