Functional Specifications
Product Operation: The reader reads the unique manufacturer's serial
number, converts it to BCD and sends it to the micro.
Switch Inputs: The reader monitors and reports the status of a normally
closed supervised door contact switch and a normally open supervised
exit request pushbutton.
Application: Intended for areas requiring a moderately low level of
security for controlled access.
Compatibility: Interfaces to CASI Micro/5-based systems.
Mounting: The reader can be mounted directly onto a standard U.S.
electrical single-gang box. The reader can also be mounted directly onto a
hollow wall. See figures on page 4 and page 5.
Indicators: Red, yellow and green LEDs and a beeper are incorporated
into the reader.
•
Red LED: If communications with the microcontroller are lost, the
red LED flashes slowly (every 2 seconds). It flashes quickly (every 400
ms) to indicate a reader tamper condition.
•
Yellow LED: Normally on when power is applied to the reader.
Flashes off briefly (100 ms) to indicate that a smart card has been read
and sent to the microcontroller. Blinks off while a key is pressed
(Model 845 only).
•
Green LED: Indicates that the microcontroller has activated the door
strike. Flashes quickly (every 400 ms) to indicate a request for PIN
entry. Upon completion of the PIN entry, the LED stops flashing.
•
Beeper: A short triple beep sounds every 30 seconds to indicate lost
microcontroller communications, a reader tamper, or supervised
switch input tamper. The beeper sounds briefly (100 ms) to indicate
that a valid smart card has been read. The beeper sounds while a key
is pressed (Model 845 only).
Supervised F/2F Mode Operation: The reader sends smart card data or
reader status data to the microcontroller approximately once every
second and waits for an acknowledgment from the microcontroller. The
reader continues sending the data until an acknowledgment is received. If
an acknowledgment is not received after the third attempt, the reader
stops reading smart cards, the red LED starts flashing slowly (every 2
seconds), and a short triple beep sounds every 30 seconds. Once the
reader receives an acknowledgment, it begins reading smart cards again,
the beeper stops sounding and the red LED stops flashing.
