Description
The DL2 is a dialer module, which contains a Digital Alarm Communicator Transmitter (DACT). The dialer sends alarm, supervisory, and trouble information to a compatible Digital Alarm Communicator Receiver (DACR) through one or two dial-up telephone lines (two per NFPA 72). The dialer supports 20 PPS 4/2 format and Dual Tone Multi-Frequency (DTMF) or Pulse mode dialing. Every 24 hours, the dialer performs an automatic test call to verify communications between the fire alarm panel and the Central Monitoring Station (CMS).
