5、irements. The components shall operate as specified herein at temperatures from 32 to 120 OF and at relative humidities up to 85 (h5) percent. 2.2 Mdor components. a. Control-Communicator, Digital (hereinafter called “DCC”) b. Keypad, Control-Communicator, Programming (hereinafter called “keypad”) c
6、. Expansion Module, Zone, Control-Communicator (hereinafter called “expansion module”) d. Transmission Device, Alarm, Cellular (hereinafter called “CATD”) Note: The DCC and CATD may be separate components which work together in an interactive system or a single integrated component. 2.3 Control-Comm
7、unicator. Dinital: 2.3.1 Primarv function. The primary function of the DCC shall be to monitor the outputs of external devices for the changes specified herein and provide notification of these changes to one or more remotely located monitoring consoles by use of the public switched telephone networ
8、k. Each device output (also referred to as a zone) will present one of the following conditions: (a) normally open relay contacts which close on alarm or change of status; (b) normally closed relay contacts which open on alarm or change of status. 2.3.2 Number of zones. The DCC shall support a minim
9、um of eight fully programmable hardwired zones and be expandable to support at least fifty-six additional zones. The additional zones may be connected to the DCC by additional hardwired zone inputs within the DCC or by means of a multiplexed polling loop using one or more expansion modules (see 2.3.
10、23) to which the device outputs are hardwired. Any hardware component required to implement the polling loop, other than the expansion modules, shall be integral to the DCC or delivered with the DCC designed for installation therein. 2.3.3 Zone response time. The zone response time (the time a chang
11、e at one of the device outputs must persist before the DCC will communicate the change) shall be not less than 1 O0 and not greater than 500 milliseconds. 2.3.4 Line supervision. Line supervision between the DCC and device outputs shall be accomplished using current supervision through end-of-line (
12、EOL) resistors located at the device outputs or by any other line supervisory technique which provides equal or greater line security. 2.3.5 Partitions. The DCC shall be configurable into a minimum of 6 partitions. Partitions shall function like separate premises, with separate zones and users. Each
13、 zone shall be assignable to any of the partitions. Users shall be able to perform system functions, such as arming and 2 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-523L7A = 9038054 0003840 283 A-A-523 17A disarming, in any selected partitio
14、n, if authorized, without affecting other partitions. The system functions the user may initiate shall depend on the users assigned authority level in that partition (see 2.3.14). One or more keypads (see 2.3.22) shall be utilized to initiate these system functions. Any partition shall be controllab
15、le from any keypad. When any keypad is being operated, data entered shall not be displayed on any other keypad. User security codes shall never be displayed. 2.3.6 Reports. The DCC shall report to the telephone number(s) programmed (see 2.3.12) when a device output changes from its normal state for
16、the minimum duration specified herein (see 2.3.3) and when system events or user initiated system functions occur that are programmed for transmittal of reports. The DCC shall be programmable to send reports when the device outputs return to the normal state (restorals). Reports shall be transmitted
17、 by digital code. The transmission data format(s) shall be compatible with various commonly used existing central station monitors and shall not be limited to one specific format. The DCC shall be programmable to transmit reports in a different communications format to each telephone number. The DCC
18、 shall be capable of conveying, as a minimum, the following information to the extent applicable: subscriber account number, the zone input that has changed and whether it is an alarm (that is, change from normal state) or restoral, type of system event or system function and user initiating the sys
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
21、her audible signaling device; or (b) a signal at an amplitude of 1.2 amperes minimum into an 8 ohm external speaker. 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
23、O O 1, 15 O 1, and 30 minutes or greater shall be selectable. 2.3.9 Auxiliary and standby power. The DCC shall provide auxiliary power of 12 to 14 Vdc at a current of at least 500 milliamperes (mA) for operation of keypads, external sensors, expansion modules, etc. The DCC shall house and maintain o
24、n float or trickle charge an internal rechargeable, lead acid battery, or batteries, capable of operating the DCC for a minimum of eight hours, while delivering the auxiliary current of 500 mA with no alarms. After restoration of 1 15 Vac power and while in normal operation in the non-alarm state, t
