Summary
Summary
The Dialog Telephone Interface Module (DTIM) is a battery operated communication link
between the security system control panel and the central monitoring station. The DTIM
receives radio signals from the panel, then uses the phone line to report security system events to
the central monitoring station.
between the security system control panel and the central monitoring station. The DTIM
receives radio signals from the panel, then uses the phone line to report security system events to
the central monitoring station.
The DTIM provides added security by separating the telephone interface from the panel. If the
panel is damaged during a break-in or fire, the DTIM can still report to the central monitoring
station.

The DTIM is a supervised device that transmits supervisory signals every hour for the panel to
receive. When the battery is low, the module transmits a low battery signal.
receive. When the battery is low, the module transmits a low battery signal.
Note
The DTIM does not have a backup power supply. Therefore, the battery must be replaced within 7 days
when a low battery condition occurs to ensure that system events can be reported. If the battery is
allowed to completely drain, the panel identifies the DTIM as being in a supervisory (non-working)
state, which prevents system events from being reported.

Installation Guidelines
•
Before permanently mounting to a wall, test the DTIM from the desired location to ensure
communication with the panel. This means you must first add (learn) the DTIM into panel
memory, then perform a sensor test.

•
Mount the module within 100 feet of the panel, but not closer than 10 feet to another DTIM

or the panel.
•
Always mount the DTIM in the upright vertical position.
•
The DTIM can be connected to a standard analog (loop-start) phone line, with or without
digital subscriber line (DSL) service.
digital subscriber line (DSL) service.
Note
The DTIM cannot be used on digital or PBX phone lines, which are designed only for digital type
devices that operate anywhere from 5 volts DC and up. The DTIM uses an analog modem and does
not have a digital converter, adapter, or interface to operate with such systems.

•
When connecting the DTIM to a standard analog phone line, it is recommended that you
install an RJ-31X jack (CA-38A in Canada) ahead of all phones and other devices on the line
for full line seizure. This allows the DTIM to take control of the phone line when an alarm
occurs, even if the phone is in use or off-hook. It also provides customers with a quick dis-
connect in case the DTIM malfunctions, allowing them to use their phone.
