TrueAlert ES Operation Advantage (Cont’d) 

 

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 Self-Test and Magnet Test 
features improves installation efficiency. TrueAlert device 
reports conveniently identify information about each 
connected appliance. 

TrueAlert ES Diagnostics 

 

Test Features.

 When 

IDNAC SLCs are in 

diagnostic 

mode, 

Self-Test 

and 

Magnet Test

 features provide individual 

appliance testing. With the 

Self-Test

 feature, 

appliance 

operation can be confirmed without leaving the control panel

.

 

Additionally, each appliance’s LED can be selected to pulse 
when it receives a supervision poll during normal operation. 

Self-Test Details.

 Selecting Self-Test Mode from the control 

panel allows on-board sensors, depending on the device type, 
to detect its own strobe and/or horn output and then report their 
status to the control panel. 

 

TrueAlert ES Diagnostics (Continued) 

 

Self-Test Details (Continued).

 Operation is by selected 

VNAC appliance groups and is either automatic (all briefly 
simultaneously activated) or individually activated by applying 
a magnet. (Refer to data sheet S4100-0100 for more Self-Test 
information.)  

Silent Appliance Magnet Test.

 In this test mode, in 

response to application of a magnet, the appliance LED 
pulses sequentially to conveniently indicate the appliance’s 
address.  

Operational Appliance Magnet Test.

 In this test mode, 

after the address is indicated by pulsing the appliance LED, 
the strobe will briefly flash 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 ES appliances to its 
ability to test IDCs, NACs, and IDNet communications 

before

 

connection to the control panel

. Please contact your 

local Simplex representative for additional information.
