 CKT 154 CKT 301 CKT 401
ENCODER/TRANSMITTER UNIT
OF ALARM SIGNALS
The CKT
152/301 module is designed to operate in combination with alarm
central stations. Its function is to receive, encode and transmit
information about any changes in the status of the sites under
surveillance to a receiver station or a repeater via a radio
channel.
-
Frequency range:
CKT 154 - 136 - 174 MHz
CKT 301 - 300 -
315 MHz
CKT 401 - 405 - 470 MHz
CKP 155 - 136 - 174 MHz -
Modulation-F 3E. -
Power - 0 -10 W -
adjustable. -
Width of the
frequency channel - 12,5/25 KHz. -
Deviation - 0 - 5
KHz - adjustable. -
Supply - from 12
to 14V DC. power
consumption at idling - 10 mA, at transmission mode via radio
transmitter - up to 1,6 A. -
Each digital
encoder/transmitter is programmed with site number from 0 to
8191 and number of the receiving station for which the data is
intended 0-7. This way up to 65536 sites can be processed
simultaneously on one radio frequency. -
The
encoder/transmitter has freely programmable parameters, which is
clone via a computer or a portable programmer PP200. -
Number of
monitored zones - 8, four modes of operation with and without
inversion: through potentials, with open collector, with balance
resistors, fire sensors. Adjustable sensitivity: 100ms, 200ms.
500ms, 1sec, 2sec, 5sec, 10 sec. Masking of events ALARM,
TROUBLE. RESTORE. -
Input for
transmission the condition of the monitoring center OPEN/CLOSE
with possibility for control through potentials or open
collector. Sensitivity: 200ms, 1sec, 2sec, 5sec, 10sec, 20sec,
1min, 2min. Masking of events OPEN/CLOSE. -
Input for
transmission of information for presence or loss of 220V - with
masking of events AC ALARM and AC RESTORE. -
Transmission of
states low/restored battery, Masking of events LOW BAT and BAT
RESTORE. -
Programmable
transmission of signal TEST at intervals of 5min. 30min. 1h, 2h,
6h, 12h, 24h. Possibility for delaying the first test for up to
24 hours from the initial start. -
Each event is
transmitted 1-255 times in packs of 1-255 repeats. A constant
time is set between two transmissions l-255sec, and random time
l-255sec. Thus is avoided the loss of information by overlapping
the transmissions from several sites at the same time. -
Time for
preparation of the transmitter: 0, 10ms, 20ms, 50ms, 100ms.
100ms. 200ms. 500ms, 1 sec. -
The data is coded
in format IRCSN-III - FSK modulation for combined operation with
receiving station IGP8000 or CD1000
