** Number of message repetitions: Programmable 1 - 20 repetitions of the message.
** Station ID number.
** Input alarm criteria: Each channel shall be independently configured for “Alarm On Open Circuit”, “Alarm On Closed Circuit”, or “No Alarm” - report on inquiry only, or in lieu of alarming, accumulate equipment running time.
** Autocall Test: When enabled, the unit shall place a single round of test calls, both at the time this function is enabled and also at regular subsequent intervals until this function is disabled at the keyboard. The voice shall identify these calls as test calls.
** Run Time Meter: Each channel shall be keyboard programmable to accumulate and report the number of hours that its input contacts have been closed.
(). Nonvolatile Program Memory Retention: User-entered programming shall be kept intact even when all power is removed for up to ten years.
(). Acknowledgement: Acknowledgement of an alarm phone call is to be accomplished by pressing a Touch Tone@ “9” as the alarm call is being received, and/or by returning a phone call to the unit after receiving an alarm call, at the user’s choice.
(). Synthesized Voice: The Automatic Telephone Dialer is to communicate via a highly intelligible solid state voice synthesizer (magnetic tape loops will not be used) with an identification of its location and the specific alarm conditions(s) that exist.
(). Input Monitoring Function: The unit shall continuously monitor the presence of AC power and the status of four contact closure inputs. AC power failure, or violation of the alarm criteria at any input, shall cause the unit to go into alarm status and begin dial-outs.
(). Alarm Message:Upon initiating an alarm phone call, the system is to “speak” only those channels that are currently in “alarm status”.
(). Inquiry Message and Function: Inquiry phone calls can be made directly to the unit at any time from any telephone, locally or long distance, for a complete status report of all variables being monitored, including power status. Further, by pressing the Touch Tone® "0" ,the user may hear all user-entered programming and diagnostic counts (Cumulative counts of Call In Count, Dial Out Count, Acknowledged Alarm Count, Power Off Alarm Count). All this information shall be available by keyboard inquiry at the unit as well.
(). Power Battery Backup: Normal power shall be 105-135 VAC, 15 watts maximum. The product is to contain its own gel cell rechargeable battery which is automatically kept charged when AC power is present. The battery is to be capable of keeping the product operating, and user programming intact, for a minimum of six continuous hours in the event of power failure. Shorter backup time shall not be acceptable. The built-in charger shall be precision voltage controlled, not a “trickle charger” to minimize recharge time and maximize battery life available.
(). Phone Line:The dialer is to operate on a standard rotary pulse or Touch Tone “dial-up” phone line (direct leased line not to be required) and is to be F.C.C. approved. A regular private line is to be provided. Connection to the telephone is through an industry standard 4-pin modular jack (RJ-11).
(). Integral Surge Protection: Gas tube and solid state surge protection is to be provided on all inputs, including power, phone and signal lines. These protectors are to be integrally incorporated into the main circuit board for maximum protection. Protectors mounted external to the main circuit board shall not be an acceptable substitute. The installer shall provide a good electrical ground connection point near the unit to maximize the effectiveness of the surge protection.
(). Modular Upgrades: The system shall include expansion connectors to accommodate field upgrades for analog input monitoring.
(). Additional Features: Sealed Switches, LED Indicators, Alarm Disable Warning. Talk-Through:All keyboard and front panel switches shall be sealed to prevent contamination. Front panel LED’s shall indicate: Normal Operation, Program Mode, Phone Call in Progress, Unacknowledged Alarm, Acknowledged Alarm, AC Power Present, AC Power Failure, and Low or Discharging or Recharging Battery. On any Inquiry telephone call or On-Site status check, the voice shall provide specific warning if no dialout phone numbers are entered, or if the alarm switch is in the “disable” position, or if AC power is off or has been off since last reset. A built-in microphone shall allow anyone at a remote phone to listen to local sounds and to have a two-way conversation with personnel at the dialer.
(). U.L. Listing:The dialer shall comply with U.L. 1459 and U.L. 1950.
Dialer as manufactured by RACO, Model CB-4.
