EOL: DS1525 and DS1535 Surface Mount Seismic Detectors

DS1525 and DS1535 Surface Mount Seismic Detectors
  • Three detection systems
  • Solid state relay output
  • Adjustable sensitivity
  • Multi-point tamper protection
  • Internal and remote test capability
  • Surface or recess mountable
  • Overview
    Dimensions: 10 cm x 8 cm x 3.3 cm (3.9 in. x 3.2 in. x 1.3 in.)
    Material: Low profile, high impact cast aluminum enclosure.
    Operating Temperature: -40°C to +49°C (-40°F to +120°F) For UL Certificated installations, 0°C to +49° (+32°F to +120°F C)
    Radio Frequency Interference (RFI) Immunity: No alarm or setup on critical frequencies in the range from 26 MHz to 950 MHz at 50 V/m.
    Location: Surface mount
    Alarm: Form C solid state alarm relay. Rated at 100 mA at 28 VDC.
    Tamper: Normally-closed tamper contacts. Contacts rated at 28 VDC, 100 mA maximum. Multipoint tamper sensing system detects removal of cover, removal of the unit from the mounting surface, and attempts to burn the detector.
    Trouble: Solid state output, shorts to ground (-) when the detector is in a supervision trouble condition. Maximum current load is 25 mA Vsat at 10 mA = 0.5 VDC.
    Current: 10 mA maximum at 12 VDC
    Ripple: 2 V p-p maximum
    Voltage: 9 VDC or 15 VDC
