S.M.A.R.T. E

XTERNALLY

These functions are initially programmed during manufacturing and testing. After installation, they can

be programmed remotely via DTMF data calls, either manually or through TMA. Set the emergency

auto-dial phone numbers in accordance with your security plan. For most applications, the other function

settings will not need to be changed from their factory defaults. For details regarding configurable

options and the factory defaults, please refer to the programming section of this manual and the on-line

help available with TMA.

The emergency push button can be programmed to call three unique telephone numbers. The unique

telephone numbers include a primary telephone number and two backup, or roll over, numbers. In the

event an emergency call cannot connect to the primary telephone number (i.e., a busy signal or no

answer), the emergency phone will automatically dial the first backup, or roll over, number. Again, in the

event an emergency call cannot connect to first backup telephone number, the emergency phone will

automatically dial the second backup, or roll over, number. This sequence will continue either until the

emergency call is answered or the programmed number of retries is reached.

Each of the above S.M.A.R.T. Emergency Phones require a "Class 2" 12 V dc regulated power supply

(included) and can be connected to any of the following:

•

Central Office (CO) line to the Public Switched Telephone Network (PSTN)

•

24 V dc or 48 V dc analog station port of Private Branch Exchange (PBX), Private Automatic

Branch Exchange (PABX) or KSU.

Connection may not be made to pay phone extensions or shared service (party) lines.

: Each telephone requires a dedicated power supply. Multiple telephones cannot be

OTE

connected to a single power supply. The power supply must provide galvanic isolation between its

input and its 12 V dc output. For dc-to-dc applications, galvanic isolation is required. Galvanic

isolation (separation) is achieved by using a transformer or opto-coupler.
