F. Configuring Input 1 (Via Over the Air programming)
Input 1 can be configured to perform one of four functions and is programmable
Over-The-Air via the Uplink Dealer web site.
1. Standard Input - This mode configures the unit to be tripped from a DC voltage
ranging from 9 V DC to 12 V DC or an open collector.
2. Timed Bell - (Default mode) This mode configures the unit to be tripped from a DC
voltage ranging from 9 V DC to 12 V DC. The unit reads a pulsed voltage as a fire
signal and a steady voltage as a burglary signal. It may be necessary to place a 1K
Ohm resistor in parallel to prevent false alarms when using panels with supervisory
voltage on the bell circuit. Some panels with supervised bell circuits may require a
1K Ohm resistor in the circuit. Contact Technical Support for further details.
3. Sampled Siren* - This mode configures the unit to be tripped from a siren driver or
a panel with a built in siren driver. The unit reads a steady tone as a fire signal and a
yelping tone as a burglary signal.
*NOTE: The input assumes that a speaker is connected to the panel. If you are not
using a speaker we recommend using a Timed Bell instead of Sample Siren. This is an
option on most panels.
