Remote Shutdown
Every gForce Ultra unit has remote shutdown contacts. These are intended for a field supplied dry con-
tact or switch to be wired across two terminals. When the contactor or switch opens, the control circuit
power is interrupted and the unit shuts down, including the control panel. The control circuit is 24 VAC
and the field provided contact or switch should have a minimum rating of 10 amps. A minimum of 18-
gauge wire is recommended or use field-supplied Class 1 wiring.
The remote shutdown contacts are always terminals 1 and 2 on the terminal block designated TB3.
The unit will ship with factory wired metal jumper clip that connects terminal 1 to terminal 2. Remove
the jumper clip prior to installing the field wires.
Remote Alarm Contacts
The dap4 microprocessor control panel provides four (4) remote alarm output contacts that can be field
accessed. The contacts include a Normally Open (NO) or Normally Closed (NC) on Alarm, dry contact,
intended to be used in a control circuit not exceeding 5 amps at 24 VAC. Use field-supplied Class 1
wiring.
These programmable output contacts will close on a failure and remain closed until the alarm is no
longer present. The terminal designations for these alarm output contact pairs are:
