The Detector Series consists of the DS453Q and
DS455Q Detectors with separate transmitters and
receivers. 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.

• 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.

Externally visible alarm LED. Internal transmitter
operation LEDs. Flashing LED and voltage output at
receiver for alignment purposes.
