Section 3: Installation
This section addresses installation procedures for SLCs, NACs and optional modules, including the DACT (UD-1000),
Class A Card, and Remote Annunciators. Wiring requirements and configuration examples are included throughout this section.
Instructions for addressing SLC devices which must be completed before programming your system are also included. Please
read this section carefully before installing devices and/or modules to insure proper installation.
Note: Instructions for installing the PSN-1000/PSN-1000(E) and/or the IP Dialer accessories are located in
Sections 6 and 7, respectively.
Signaling Line Circuit (SLC) Installation
The SLC panel provides power and communication to each of the sensors and modules connected. The SLC is polled by the
system every 4–5 seconds. This panel has a loop capacity of 75 addressable points, which may be configured in any combination
of smoke sensors, heat detectors, and input or output modules.
SLC Wiring Requirements
The wiring parameters listed below MUST be followed to ensure proper installation:
•y Maximum wiring resistance between two (2) Short Circuit Isolators (SCIs) must be less than 10 ohms.
•y Total resistance must be below 50 ohms.
•y Maximum wire resistance must be calculated based on 0.1 ohm per SCI.
•y Maximum loop capacitance must be 0.5 micro farads.
•y All SLC wiring is low voltage and power limited.
