ENCODER/TRANSMITTER UNIT OF ALARM SIGNALS
CKT 154 - 136 - 174 MHz
CKT 301 - 300 - 315 MHz
CKT 401 - 405 - 470 MHz
CKP 155 - 136 - 174 MHz
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
