Description
If you need a reliable, no-fuss auto dialer that powers itself straight from the phone line and won't accidentally fire on incoming calls, the Viking K-1900-5 is built exactly for that job.
This compact hot dialer stores your programmed number in non-volatile E2 memory, so your settings are always intact even without batteries or external power. Ring detection keeps it from triggering on inbound calls, and the user-programmable security code protects against unauthorized changes. Touch Tone dialing adds an extra layer of protection against fraudulent calls from handheld dialers, making it a smart choice for secure or semi-public installations. You can also fine-tune timing with programmable pauses in one and four second increments, or adjust dialing speed between normal and fast to match your line conditions.
The K-1900-5 fits naturally into access control panels, alarm systems, kiosks, and any application where a single-button or contact closure trigger needs to automatically dial out without any user intervention or a separate power supply.
Our Expert Take: What makes the K-1900-5 particularly practical is the combination of ring detection and Touch Tone-only dialing — two features that quietly prevent a lot of real-world headaches in shared or public phone environments. If your application requires triggering the dialer from a dry contact closure rather than a manual action, Viking supports that configuration as well, which opens up a wide range of integration possibilities with alarm panels and automation equipment.
