IDNAC SLC Operation Advantage (Cont’d) 

 

Reduced current allows efficient IDNAC SLC 
operation.

 With 

IDNAC SLCs

, a 

constant

 29 VRMS 

source voltage is maintained, even during battery standby, 
allowing strobes to operate at higher voltage with lower 
current and ensuring a consistent current draw and voltage 
drop margin under both primary power and secondary 
battery standby. Efficiencies include wiring distances up 
to 2 to 3 times farther than with conventional notification, 
or support for more appliances per IDNAC SLC, or use of 
smaller gauge wiring, or combinations of these benefits, 
all providing installation and maintenance savings with 
high assurance that appliances that operate during normal 
system testing will operate during worst case alarm 
conditions. 

Reducing Installation and Testing Time.

 With 

separate controls on the same two-wire SLC, installation 
time and expense for both retrofit and new construction 
can be significantly reduced. When Class B wiring is 
used, 

wiring can be “T” tapped

, allowing more savings in 

distance, wire, conduit (size and utilization), and overall 
installation efficiency. Use of the magnet test feature 
improves installation efficiency. TrueAlert device reports 
conveniently identify information about each connected 
appliance. 

 

TrueAlert Addressable Wiring Isolator  

 

Isolator Model

 

4905-9929 

is available for remote 

mounting on TrueAlert addressable circuits to isolate 
short circuited wiring from functioning wiring. (Refer to 
data sheet S4905-0001 for additional information.) 

TrueAlert Addressable Diagnostics 

 

Test Features.

 Controllers can be selected to pulse each 

appliance’s LED when it receives a supervision poll. 
When the controller is selected for diagnostic mode, the 
appliance magnet test feature provides a response at the 
individual appliance being tested.  

Silent Appliance Magnet Test.

 In this test mode, in 

response to the magnet test, the appliance LED pulses 
sequentially to conveniently indicate the appliance’s 
address.  

Operational Appliance Testing.

 In this test mode, 

after the address is indicated by pulsing the appliance 
LED, the strobe will briefly flash and the horn will briefly 
sound to indicate proper operation. 

TrueStart Instrument Two (TSIT).

 The 2nd generation 

of the Simplex TrueStart Test Instrument adds testing of 
IDNAC SLC wiring and TrueAlert (and TrueAlert ES) 
appliances to its ability to test IDCs, NACs, and IDNet 
communications 

before

 

connection to the control panel
