Wiring Guidelines
Although the SAFEPATH
®
Panel products incorporate signal verification and noise filtering circuitry
on their inputs, induced voltages or noise on the input wiring can cause improper operation.
Therefore, use shielded twisted pair wire for all dry contact input wiring.
The shield of each cable should be connected only at one end. Each shield of each cable that
connects to the SAFEPATH
®
Panel is to be connected to the grounding points provided near
the knockout locations on the chassis (see Figure 3-17 on Page 3-16).
All input and output circuits on the Dual-Circuit SAFEPATH
®
Panel are considered non-power
limited circuits. Power limited wiring within the SAFEPATH
®
Panel must have a 1/4” separation.
ALL SAFEPATH
®
PANEL DRY CONTACT INPUT WIRING AND AUDIO
WIRING SHOULD BE ROUTED AWAY FROM ANY HIGH VOLTAGE OR
HIGH CURRENT WIRING (SUCH AS AC OR DC WIRING, AUDIO POWER
WIRING, AND MOTOR OR RELAY ACTUATION WIRING). DRY CONTACT
WIRING SHOULD BE INSTALLED IN SEPARATE CONDUIT FROM THESE
WIRINGS. FAILURE TO DO SO MAY CAUSE LELECTRICAL SHOCK
RESULTING IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH
TO YOU AND /OR OTHERS.
The National Electric Code limits the maximum number of conductors that can
be installed in conduit and wiring boxes depending on the size of the conduit,
the volume of the boxes, and the gauge of the wire used. Make sure that
wiring used for SAFEPATH
®
Panel installation complies with the latest NEC,
NFPA, Local, State, County or Province requirements.
Field Wiring Connections
All SAFEPATH
®
Panel wiring terminals are designed to accept #12 AWG through #22 AWG wiring
(one wire per terminal). Proper wire gage considerations for the Notification Circuit must take into
account current requirements versus length of run.
Prepare System Wiring Diagram.
1. Prepare a system-wiring diagram to include all Notification Appliances, ancillary equipment,
and internal connections and power sources as required.
THE MAXIMUM CURRENT OUTPUT OF THE DUAL-CIRCUIT SAFEPATH

Visual Notification Appliance Output Wiring
Available alarm strobe current varies depending on the amount of alarm current used by the
Dual-Circuit SAFEPATH
®
Panel modules without the strobe function. The audio alarm current of
the amplifier module(s) depends on the number of speakers on the circuit, length and gauge of
wire of the audio circuit, and the audio mode in use. Table 3-1 shows available strobe current for
each model using the standard calculation for a Temporal Code 3 signal. The SAFEPATH
