14.4 Connecting Alarm Inputs
An 8-position terminal block on the lower left edge of the STAR-ELT is used to connect to dry
contacts from a fire panel. Each pair of zone inputs should be connected to the two sides of one
normally open dry contact at the panel. There is no preferred polarity to this connection. There
are four such “zones” in the 8 connection points.
A bi-color indicator LED is located immediately to the right of each pair of contacts on the
terminal strip: Red indicates when the input is in an Alarm condition (dry contact closure);
Yellow indicates when the input is in a Trouble condition (wire breakage or ground fault).
Opens, shorts and ground faults are detected individually by each input zone.
All input zones must be connected to a 10 kΩ termination resistor at the end of the last open
contact device being monitored. The termination resistor must be placed across the dry contacts
at the end of the last device. If an input zone is not used the termination resistor leads must be
inserted directly into the terminal strip for that zone, if no termination resistor is connected to an
input that zone will be in a trouble condition.
All of the trouble indications are combined to create a single input trouble condition. These
trouble conditions can be transmitted as any function in the wireless system with a response
delay of up to 65 seconds. Thus, the STAR-ELT can be programmed not to respond to a trouble
condition unless it remains in trouble for a period of time. This feature serves to prevent spurious
trouble messages when work is being done on the system.
