designed specifically for use with the Telecenter ICS system. One ICSIAM is included with each ICSBASE, ICS2BASE, ICSBASERM, and ICS2BASERM. A second ICSIAM can be added to each ICSBASE, ICS2BASE, ICSBASERM, or ICS2BASERM to expand the Telecenter ICS system to two intercom channels.

i. The ICSIAM incorporates low-distortion, balanced Listen mode input and Talk mode output amplifiers that provide the voice communication between the administrative user on a telephone and a classroom/intercom speaker. The ICSIAM has an Automatic Gain Control (AGC) in the Listen Mode that assists in amplifying soft voices along with limiting very loud voices; this optimizes the Listen intelligibility in an intercom environment. The AGC has an adjustable threshold control for adapting to various acoustic environments and can also be defeated if desired. To further enhance the voice intelligibility of the Telecenter ICS system, the ICSIAM frequency response has been shaped to match that of the human voice.

j . The ICSIAM automatically switches between talk and listen modes based on whether the administrative user (on the telephone) is speaking or not. This automatic (VOX) switching provides for hands-free intercom at the classroom/intercom speaker. A control is provided to adjust the automatic VOX switching sensitivity to suit the administrative users’ preference. The ICSIAM also provides for manual Push-To-Talk (release to listen) override of the automatic talk/listen switching of the intercom channel by the administrative user.

2.6 NTP SYNCHRONIZED WIRELESS CLOCK SYSTEM – Retrofit and New Construction

A. The DISD preferred system including PA, clocks, and GPS is manufactured by Rauland Corporation as specified in the revised Appendix F.


B. This Section includes a NTP Synchronized Wireless Clock System. It includes requirements for a NTP Synchronization system components including, but not limited to, the following: 1 . Transmitter 2. NTP Receiver module 3. Wireless Corrected Analog Clocks (24VAC powered option) 4. Wireless Corrected Analog Clocks (Battery Powered for user placement)

C. System Description; 1 . The NTP Synchronized Wireless System consists of a master transmitter located on the

inside of the building, and a NTP receiver connected to a time server. An unlimited number of wireless analog and digital clocks are synchronized to the NTP time.

2. System shall synchronize all clocks to each other. System shall utilize NTP technology to provide atomic time to components.

3. System shall not require hard wiring for its components except for AC Power. Analog Clocks may be battery operated for full portability if required.

4. Analog Clocks shall synchronize to +/- 1 second of the transmitter displayed time. 5. Clocks shall automatically adjust for Daylight Saving per settings on the transmitter 6. The system shall have an internal clock that is continually updated by the NTP receiver. If

a NTP failure were to occur, the clocks would continue to be synchronized to the internal clock and would not deviate from each other. Once NTP time is restored, all clocks would once again be synchronized to the NTP time.

7. The system must have a failsafe design so that if a power interruption were to occur, the clocks will continue to operate. If a synch signal is not received by the analog clocks for 48 hours, the second hand will double pulse to indicate this condition. Upon restoration of power, the transmitter will once again communicate with the clocks and normal operation will resume.

8. Battery Powered Analog Clocks shall require 2 “D” cell batteries. 9. System shall be 100% programmable from the front operational panel with lights that

indicate power status and NTP reception. Panel programming will also include Time Zone, Frequency, 12 or 24 hour operation and DST on/off.

10. The wireless backbone must support expansion of the system to include wireless alphanumeric displays for emergency crisis communications.

11 . The system may be modified to use GPS instead of NTP as the time source without the need to replace the transmitter. A GPS receiver would need to be added with access to the outside of the building.

12. The system shall lend itself to expansion by simple addition of wireless secondary clocks and their required power source.
