The ELK-M1TWI is an interface that can add up to 3 zones of two-way listen-in to the M1 Gold Control Panel.
Two-way listen-in gives central station the ability to check in with residents after an alarm to make sure the alarm wasn't accidentally tripped. The interface also lets users use a telephone to check in on other residents (children, elderly parents).
