H.6 Local Alarm Relay Option
The Verbatim provides a 5 volt output that is turned on whenever the unit goes
into alarm. This is available at JB4, located at the top center of the main board.
Use a molex style 2 pin connector to plug onto the JB4 pins. This output can
activate a sensitive (500 ohm +) relay such as a Potter & Brumfield KHU-
17D11-6). Connect a 150 ohm,1/4 watt resistor across the relay coil. The Potter
& Brumfield relay plugs into a socket (#27E166) which is shown in the accom-
panying figures. Note that it has four separate circuits in SPDT form. This relay
may be used for local alarm, line seizure, or both.
H.6.1 Local Alarm Relay Configuration
1. Wire the relay coil as described in the introduction.
2. Wire the local alarm to one of the four circuits of the relay. In the illustra-
tion, the numbers refer to the four separate circuits, and C refers to the coil
terminals.
3. Note that the Verbatim does not provide the power for the alarm, it
functions only as a switch.
4. The program code for Local Alarm Relay configuration is
960 00 ENTER
which is the factory default.
