Section 3: Installation
is section addresses installation procedures for SLCs, NACs and several optional modules, including the DACT
(UD-1000), Class A Card, and Remote Annunciators. Wiring requirements and conguration 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
e SLC panel provides power and communication to each of the sensors and modules connected. e SLC is
polled by the system every 4–5 seconds. is panel has a loop capacity of 75 addressable points, which may be
congured in any combination of smoke sensors, heat detectors, and input or output modules.
SLC Wiring Requirements
e 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.
