Fast and easy installation

Built for speed in every way, the FireFinder system

contains revolutionary SureWire technology that

can help eliminate installation errors and reduce

installation time by up to 25%.

This technology includes:

Device Programmer and Loop Tester Unit

(DPU) – FireFinder is the only intelligent system

equipped with this powerful tool that will save

many hours of installation time! The DPU allows

installers to test and verify the correct connec-

tion of devices as they are installed instead of

waiting until the end of installation to test at

the fire panel. It instantly communicates with

devices and confirms whether they’re functioning

properly, reporting individual device addresses,

the type of each device, and a summary of total

devices on the loop according to type (i.e.:

# Manual Stations, # Smoke detectors, etc.).

The DPU will also check detector loops for

ground faults and shorts.

Polarity Insensitive Detector Loop Wiring*–

Another big time-saver, polarity insensitive wiring

allows fire detection devices to operate flawlessly

even when detector and module wiring polarity

are inverted on the wrong screw terminals.

When wiring polarity doesn’t need to be observed,

wiring troubleshooting is greatly reduced.

Ground Fault Detection by Module – Ground

faults are easily the most time-consuming wiring

problem to locate in a detection system. But the

FireFinder system greatly simplifies locating

the problem by identifying the specific pair of

wires that contain a ground fault.

Use of Any Existing Wire – The system can be

connected to existing field device and notifica-

tion circuit wiring, which saves time and money

on retrofits.

To further reduce installation

costs, there’s no need for shielded wire on intel-

ligent detector loops, notification appliance

circuits or telephone circuits which may cause

more ground faults.

Windows™ Configuration Program* – A simple,

Windows-based configuration tool makes pro-

gramming faster and easier for all levels of

programmers, from system design engineer

through installing technician. It also allows

configuration programming to be created and

changed in less time.

* Patents pending.

** Use of existing wire requires approval of

local authority having jurisdiction.

Hand-held Device Programmer and Loop

Tester helps reduce installation time.
