OTEK FS Series Quick Start Manual

R.F.

RCVR
DESCRIPTION (General):
OTEK's "FS" Series exclusive Fail-Safe feature con-
sists of a periodic "check-in" signal (independent of the
alarm or count signals) sent by the transmitter every
minute to the receiver to assure proper communication.
If the receiver fails to receive up to two (2) "check-in"
signals (2 minutes max.) it will blink its red LED and
beep its buzzer to "WARN" you of the problem. The
receiver has a safety screw to secure it to the AC wall
plate and a 9V battery back up for continuous opera-
tion in the event of power failure.
Two Transmitter packages are availble: the AC pow-
ered with battery back up and optional counter, and the
miniature (1 X 1.5 X 2") case for panel, chassis, pipe
or DIN Rail mounting. Both models have either inter-
nal or external sensors.
The Receiver has an AC wall plate mount case with
security screw, relay (.5A/120VAC SPDT) output and
optional 9V Battery backup, 6 digit counter and
EEPROM with TTL output for "TOTAL COUNT"
or "ALARMS" accumulated.

DESCRIPTION (BY FUNCTION) &
APPLICATIONS:
Option: 00
A. Transmitter: You apply a positive (or open)
pulse-level to the transmitter and it transmits the
"Alarm" Code.
B. Receiver: Turns on & latches its LED, buzzer
and relay until manually reset and accumulates the
count in the optional counter and/or EEPROM.
Applications:
Entry, Over/Under Temperatuer, Pressure, Flow,
Speed, Etc. Just Connect Your Own Sensor To It
and Control It Wireless!
Option: 01
A. Transmitter: Detects Angular Position/Shock/
Vibration greater than 15° off horizontal and trans-
mits the alarm code.
B. Receiver: Turns on & latches its LED, buzzer
and relay until manually reset and accumulates the
count in the optional counter and/or EEPROM.
Applications:
safe area communication, machinery preventive
maintenance, structures, buildings, bridges,
transportation, tilted loads, etc.
Option: 02
A. Transmitter: You connect any two insulated
wires (bared tips) to the transmitter and drop the
other end to the desired level of detection. Upon
detecting the liquid (conductivity) it will transmit
the Alarm Code.
B. Receiver: Turns on & latches its LED, buzzer
and relay until manually reset and accumulates the
count in the optional counter and/or EEPROM.
Applications:
age tanks, ponds, plating baths, fuel storage, haz-
ardous liquids, etc.
