7.2.4 Operation
The SDACT(-2) uses SIA codes to report to the central station. The CP-3500D will send the device
Point I.D. and applicable SIA codes to the SDACT(-2) serial port input. This information will also be
communicated to the central station by the SDACT(-2) as supplemental information. Table 4 shows
the CP-3500D events and the corresponding SIA codes that will be communicated.
When an alarm is received by the CP-3500D one of the alarm relays A, B or C will trip and activate
the appropriate zone on the SDACT(-2) communicator. The SDACT(-2) will transmit its programmed
SIA code for that zone input to the central station along with the Point I.D. and SIA code from the CP-
3500D. Acknowledging the alarm on the CP-3500D will only silence its internal sounder. The
sounder on the SDACT(-2) CANNOT be silenced by pressing the ALARM ACK key on the CP-3500D.
The SDACT(-2) will silence its sounder and fully reset only when the CP-3500D RESET key is
pressed and the SDACT(-2) has finished communicating to the central station. A restore signal will be
sent to the central station upon resetting the CP-3500D.
When a supervisory alarm is received by the CP-3500D, the Alarm C relay will short causing a
supervisory transmission to be sent from Zone 3 on the SDACT(-2). Acknowledging the supervisory
on the CP-3500D will only silence its internal sounder. The sounder on the SDACT(-2) CANNOT be
silenced by pressing the SUPERVISORY ACK key on the CP-3500D. The SDACT(-2) will silence its
sounder and fully reset when the CP-3500D is reset either by pressing the RESET key or all self-
restoring supervisory alarms are restored and the SDACT(-2) has finished communicating to the
central station. A restore signal will be sent to the central station upon restoring the CP-3500D to
normal standby.
When a trouble is displayed by the CP-3500D, the N.C. contacts on the trouble relay will open
causing a trouble transmission to be sent from Zone 4 on the SDACT(-2).
Note: A dialer fault
trouble will not activate the CP-3500D trouble relay.
Acknowledging the trouble on the CP-3500D
will only silence its internal sounder. The SDACT(-2) will silence its sounder and fully reset when the
CP-3500D is reset either by pressing the RESET key or all self-restoring troubles are restored. Note:
Central station notification of A/C loss in the CP-3500D and SDACT(-2) will be delayed by 120
minutes. If A/C is restored prior to 120 minutes then no signal will be communicated to the central
station. If A/C is restored after the 120 minute delay then the CP-3500D and SDACT(-2) will restore to
normal standby automatically unless another trouble is pending. A restore signal will be sent to the
central station upon resetting the CP-3500D or self-restoration of an A/C loss. Note: Any trouble
condition on the CP-3500D will be sent with a Point I.D. of 3500.
If any trouble condition occurs as a result of a problem with the SDACT(-2) it will be annunciated on
the CP-3500D as a Dialer Fault. Refer to the Keltron SACT manual to determine the exact problem
with the dialer. The SDACT(-2) will communicate the trouble to the central station. Fixing the trouble
with the SDACT(-2) will automatically restore the dialer fault condition on the CP-3500D. Note: A
trouble with the CP-3500D will also display a Dialer Fault however in this scenario the CP-3500D
trouble condition will also be displayed. The SDACT(-2) will only restore to normal when the CP-
3500D trouble condition is resolved. When the CP-3500D is put into test mode a TS (start test) and
FT (fire trouble) SIA code will be communicated to the central station. While in test mode Alarm,
Supervisory, Trouble or Point I.D.’s will not be communicated to the central station.
