Can I connect an external alarm or auto-dialer to the TV2?

Yes. The TV2 has a normally open, dry-contact relay that closes whenever an alarm condition is active. Run a two-conductor cable from the relay terminals to a sounder, strobe, building alarm input, or auto-dialer. Several monitors can share one star-wired run into the same dialer input.

The relay is rated for under 30 V and is fused at 0.5 A, so it switches a low-voltage circuit rather than powering a device directly. Alarms are enabled per sensor with a high limit, a low limit, and a delay so that a door opening or a defrost cycle does not trigger the alarm.

With the optional auto-dialer the TV2 can place phone calls that play a sixteen second recorded message to a list of people you choose.
