OCB-DIALER911

OCB-DIALER911: Automatic PSTN Emergency Voice Dialer

In standalone intruder alarms, fire monitoring panels, environmental sensors, and panic button stations, transmitting instant emergency notifications directly to property owners, off-site responders, or security monitoring staff is essential. The OCB-DIALER911 is an automatic telephone voice dialer engineered to bridge local alarm control panel trigger outputs with standard PSTN (Public Switched Telephone Network) landlines or cellular terminal interfaces.

Programmable Emergency Contacts & Custom Voice Messaging

Equipped with non-volatile internal EEPROM memory, the OCB-DIALER911 allows users to program multiple telephone numbers (up to 4 to 9 contact numbers depending on configuration). Upon activation, the unit dials each programmed number sequentially. Integrated audio recording circuitry allows recording a custom voice emergency message (up to 20 seconds), which plays automatically when the recipient answers the call.

Universal Trigger Input & Non-Volatile Memory

Designed for universal compatibility with security equipment, the OCB-DIALER911 accepts dry contact triggers including Normally Open (N.O.), Normally Closed (N.C.), or positive/negative DC voltage signals from control panel alarm outputs, panic buttons, or water leakage sensors. The device includes a telephone line status check to detect line cuts, on-board keypad programming with LED/LCD display feedback, and password protection against unauthorized tampering.
