6.18  EST3 Installation and Service Manual 
Detector, input module, and output module testing 
The procedures listed in this section should be performed on the 
detectors, input modules, output modules, and related accessories 
connected to each cabinet. These procedures are designed to test 
the devices and the network applications programming. 
Note: The network configuration, Signature Control module 
information must be downloaded into the network and Audio 
Source Unit, using the System Definition Utility (SDU) program, 
before starting testing. 
Every circuit connected to the EST3 system should be visited, 
and manually activated during the installation process to verify 
that: 
1.  The installed location meets proper engineering practices. 
2.  The location annunciated by the system agrees with the 
physical location of the device. 
3.  That the activated device initiates the correct system 
response. 
Duct detectors should be tested to verify that both minimum and 
maximum airflow requirements are met. 
Signature Series detectors and bases on a 3-
SSDC(1) module circuit 
1.  Verify that all components are installed using accepted 
workmanship standards. 
2.  Individually activate each detector. Verify that the 
appropriate Alarm and location message is displayed on the 
LCD module. Verify that the detector initiates the 
appropriate system responses. If the detector is installed in a 
relay base, verify that the base’s relay function operates 
correctly. If the detector is installed in an isolator base, 
verify that the base isolates the required circuit segments. 
Caution: Do not use magnets to test Signature series detectors. 
Doing so may damage the detector electronics. Instead, use an 
approved testing agent (e.g. canned smoke.) 
3.  Duct mounted detectors should be tested using an air 
velocity test kit (6263, 6263-SG) to verify that 
minimum/maximum airflow requirements are met. 
4.  Remove the detector from its base. Verify that the 
appropriate Trouble and location message is displayed on the 
LCD module.
