Quad beam detection
▶
Four mounting options using optional mounting poles
▶
Environmental discrimination circuit
▶
Beam power control to reduce cross-talk
The Detector Series consists of the DS453Q and DS455Q
Detectors with separate transmitters and receivers each.
The transmitter emits an invisible infrared beam to the
receiver. If the beam is broken, the receiver signals an
alarm.
The DS453Q and DS455Q use four pulsed infrared beams
that are designed to activate an alarm only when all four
beams are simultaneously blocked.
The DS453Q and DS455Q also feature interlocked upper
and lower beams, signal voltage LED, and selectable
environmental discrimination circuitry.
Functions
Environmental Discrimination Circuit
•
Monitors gradual loss of signal due to dust, fog, rain,
and snow. Normally closed output opens when signal
loss reaches 90%. May be field configured to bypass
alarm relay when activated.
•
Field adjustable sensitivity, normally closed relay
contacts rated 0.2 A, 30 VDC.
Test Features
Externally visible alarm LED. Internal transmitter operation
LEDs. Flashing LED and voltage output at receiver for
alignment purposes.
