sor System
7.1. Status LEDs
7.1.1. RF Sensors
All RF Sensor models have a single LED on
top of the enclosure. This LED will flash once ev-
ery three seconds to indicate the sensor is operat-
ing in Clean mode. Aside from Clean mode, there
are only three events that will cause the LED to
be ON.
1. The LED will be ON for one second when
you activate the sensor (see Section 4.2., Ac-
tivation).
2. The LED will flash twice when you switch
the sensor into Sleep mode (see Section 7.5.,
RF Sensor Sleep Mode).
3. The LED will flash once each time you press
the Service Button while the sensor is in Ac-
tive mode. This indicates the sensor is not in
Sleep mode.
7.1.2. RF Receivers
The RF Receiver has three LED indicators:
the STATUS LED, the RF LED, and the TOKEN
RING LED.
7.1.2.1. The Status LED
The STATUS LED flashes GREEN once per
second to indicate the receiver is ON. If this light
does not flash, the receiver is unpowered.
7.1.2.2. The RF LED
The RF LED flashes RED every time it
receives a transmission from an RF Sensor. In a
properly working system, this light should flash
occasionally several times over the course of 3-5
minutes. If after five minutes the LED does not
flash at all, there may be a problem with the
receiver.
7.1.2.3. The Token Ring LED
The TOKEN RING LED flashes ORANGE
when it sends transmission data to the RF Gate-
ways. The rate at which this light turns ON
depends on the number of receivers on site,
because RF Receivers take turns sending col-
lected data to the gateways. In a properly work-
