Model 5883 Relay Interface Board

The following instruction describe how to install
the 5883 to a Silent Knight Addressable fire
control panel. Refer to the control panel
installation manual (P/N 151139 or 151209) for
programming instructions.

The 5883 is a relay interface board that has 10
general purpose Form C relays that can be used
for activating voice evacuation, elevator recall or
HVAC fan cut-off, as examples.

Each relay is activated by an open collector
input from a controlling device such as a 5880.

Wiring

Note: Installation and wiring of this device must be done

in accordance with NFPA 72 and local ordinances.

Important! All wiring is supervised and power limited.

Connecting the 5883 to Aux power

Connect the power terminals of the 5883 to a 24
VDC power supply as shown in Figure 2.

Figure 2: Auxiliary Power Connections

Note: Auxiliary power is supplied by a Regulated UL

listed power supply for Fire Protective Signalling
Systems.

Auxiliary Power Using Flexput™ Circuits

The 5883 can use aux power from any 24 VDC
source. The following describes how to use the
Flexput circuits as the auxiliary power source:

1. Connect the aux power wires to the Flexput terminals using “X” terminals as positive, and “O” terminals as negative power. See Figure 3.

Figure 3: Flexput Auxiliary Power Output

2. Configure the auxiliary power output for constant output through programming. Refer to the control panel installation manual (P/Ns 151139 & 151209).
