These small and versatile modems are specifically designed to meet the stringent requirements for industries including Medical Services, Business & Home Security, Remote Monitoring & Data Collection and more.

These controller based modem modules support Ademco's DTMF Contact ID protocol published by SIA (Security Industry Association).  Utilizing standard DTMF tones and selected AT Commands, the HM4-RC family may be provisioned to transmit event and emergency signals to almost any monitoring station.  The HM4-RC can detect "Kiss-off" tones and then restore the telephone line for standard voice communications.

The HM4-RC family also complies with IEC60601-1 with 3KV breakdowns.  The telco and medical certifications are transferable to the integrator to allow easy integration to almost any platform.

Measuring only 1.0" x 1.0" x 0.25", the modem has a built-in data pump, controller and on-board International DAA.  Ready to operate with simple AT commands, the family will function on any OS (operating system).  Its cost-saving line-in-use feature eliminates the need for maintaining a dedicated phone line in many applications.

The modem provides 300 bps to 56k bps data rates and up to 14.4k bps fax operation.  The flexible family may be provisioned for Telephone Answering Machine capabilities with on line voice playback, recording, and DTMF tone detection and generation.  Other features include Caller ID, Modem-on-Hold, Caller waiting detection, Data/Fax/Voice call discrimination, Quick connect, and Extension pickup detection.  Modem customization is available through patch code that can be stored in modems on board memory.
