19、tem function. 2.3.7 Operating; power. The DCC shall operate from nominal 60 Hertz, 1 15 volts alternating current (Vac), wired directly to the DCC or from the output of an external transfonner which plugs into a nominal 1 15 Vac outlet. The DCC shall perform its normal signaling functions when energ
20、ized by voltages from 85 to 1 1 O percent of the nominal voltage. 2.3.8 Audible signaling device power. The DCC shall provide either or both of the following outputs for operating an audible signaling device: (a) a nominal 12 volt dc (Vdc), 1 ampere minimum, output for operating a bell, siren, or ot

If option (b) is provided, both a steady tone and either a warbling or yelping tone shall be provided and shall be user selectable. The DCC may draw supplementary power from the stand
22、by battery when the audible signaling device is sounding. The output to the audible signaling device shall be initiated by receipt of an alarm condition at a zone input programmed to initiate this output. The duration of this audible output shall be programmable. As a minimum, durations of 5 O 1, 1

26、1 O Operation on ac Dower failure. Upon loss of ac power, the DCC shall immediately operate from battery power. Loss or subsequent restoral of ac power shall not cause a false alarm. The DCC shall, if programmed, initiate a report of the loss of ac power to the phone number) dialed (see 2.3.12) not
27、less than 30 seconds nor more than 40 minutes after ac power loss occurs. No report shall be sent if power is restored prior to transmittal of the report. The keypad shall indicate loss of ac power not more than 120 seconds after ac power loss. 2.3.1 1 Low battery indications. When the DCC is operat
28、ing from standby power, the battery voltage shall be monitored, and a report indicating a low battery shall be transmitted before the DCC becomes unable to perform its functions. When the DCC is operating from ac power, the DCC shall check the battery condition under load at least daily and shall tr
29、ansmit a low battery signal if the battery would be unable to properly perform its standby function. A low battery indication shall also be made at the keypad. 2.3.12 Dialing modes. The DCC shall be programmable to transmit reports of changes at its zone inputs, system status changes and user operat
30、ions to at least two telephone numbers. As a minimum, the DCC shall provide the following dialing mode options: a. transmit reports to the primary phone number; if the transmission attempt to this number is unsuccessful after a preset or programmed number of dialing attempts, transmit to a second nu
31、mber (back-up reporting); b. transmit reports to the primary number, then to the secondary number (dual reporting). In this mode and in mode a. the DCC may alternate dialing between the two numbers after one or two unsuccessful attempts to the alternate number; zone change reports) to the secondary
32、phone number. c. transmit zone change reports only to the primary phone number and all reports (including If attempts to report are unsuccessful, a total of at least 8 attempts shall be made per phone number before dialing attempts are discontinued. An indication of the communications failure shall
33、then be made at the keypad. 2.3.13 Programming. The DCC shall be fully programmable in the field with the same keypad used for system control (see 2.3.22). Programming with the keypad shall require entry of a programmable four, or greater, digit code (installer code). It shall also be possible to do
34、wnload and upload program data and to perform primary user control functions from a remote location. The DCC shall incorporate an optional downloadhpload callback technique. When programmed for this option, after receiving an initial call from a remote location requesting downloadinghploading, the D
35、CC shall be required to call a preprogrammed phone number from which the downloadinghploading can proceed. 2.3.14 User operations. To perform arming, disarming and other system functions, it shall be necessary to enter a four or more digit code (user code). At least 32 user codes shall be 4 Provided
36、 by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-523 17A assignable. Operations (that is, system functions) a given user may perform shall be determined by the authority level assigned to that user. A master user shall be capable of performing all possibl
37、e system functions and assigning other user codes and authority levels, except the master level. As a minimum, other authority levels shall include the following: one that allows the user only to arm and disarm the DCC, but not to perform other system functions such as bypassing zones, viewing the l
38、og, etc.; one that allows the user only to arm the DCC, or, one that allows the user to arm the DCC and also to disarm it if that user was the person who armed it. The DCC shall allow a user to transmit a duress alarm report by appropriate keypad entry without annunciation of an alarm at the keypad
39、and external sounder. 2.3.15 Zone types. The DCC shall provide, as a minimum, two types of zones, a 24-hour zone and a delay zone. For zones programmed as 24-hour zones, changes at the zone inputs shall be immediately reported to the monitor station regardless of the arming status. For zones program
40、med as delay (entry/exit) zones, an alarm occurring when the system is disarmed shall be ignored. The DCC shall be armed by keypad entry of an appropriate user code and keystroke or keystrokes. Arming the DCC shall initiate the exit delay period. Alarms received during this period shall be ignored.
41、After expiration of the exit delay period, receipt of an alarm shall initiate the entrance delay period. If the DCC is disarmed by a user before expiration of the entrance delay period, alarms received during the entrance delay period shall be ignored. If the DCC is not disarmed before expiration of
42、 the entrance delay period, an alarm report shall be transmitted to the monitor station(s) and local annunciation shall occur if programmed. The entrance and exit delay periods shall be independently programmable. At least two sets of delay times shall be selectable. Selectable times shall range fro
43、m 15 seconds or less to at least 150 seconds in increments no greater than 15 seconds. 2.3.16 Real time clock.
