SLC Circuits without Isolators Overview This chapter concerns itself with the two styles of circuits that do not require isolation devices: • NFPA Style 4 • NFPA Style 6 NFPA Style 4 SLC NFPA Style 4 requirements can be met by using the diagram below. Addressable Detector Addressable Module T-tapped Circuits B+ B– SLC-style4.cdr Control Panel SLC Figure 9 Basic NFPA Style 4 SLC ADT SLC Manual 51348:A 8/29/00 17 . • T-tapping of the SLC wiring is allowed for Style 4 configuration.

Upon powerup. the control panel registers a trouble condition for each addressable device which is isolated on the SLC segment or branch. This isolates the faulty branch from the remainder of the loop preventing a communication problem with all other addressable devices on the remaining branches (labeled “Continuation of the SLC” in the figure below). When more than 100 Isolator Modules and/or Bases are connected to an SLC loop.cdr SLC Isolated branch of the SLC Figure 11 Wiring an M500-X Module ADT SLC Manual 51348:A 8/29/00 19 . an integral relay is latched on. the maximum number of addressable devices that can be connected between Isolators is reduced to seven. Fault Isolator Module . The module detects the short and disconnects the faulted SLC branch or segment by opening the positive side of the SLC (terminal 4). Due to the heavy current draw of the 3251 Multi-Sensor Detector the maximum number of these detectors that can be installed between isolator modules is reduced to two (2). Wiring an Isolator Module The figure below shows typical wiring of an Isolator Module: Continuation of the SLC IN IN OUT OUT SLC-isowire. Isolator modules will not function properly when these limits are exceeded. SLC Circuits with Isolators Overview There are two isolator devices used to protect critical elements of the SLC from faults on other SLC branches or segments: • Fault Isolator Module M500X • Isolator Detector Bases A Fault Isolator Module on both sides of a device. During a fault condition. the module automatically reapplies power to the SLC branch or segment. or the combination of an Isolator Base and Isolator Module are required to comply with NFPA Style 7 requirements. the address capacity of the loop is reduced by two (2) addresses for every isolator device in excess of 100. When relay or sounder bases are used. Once the fault is removed. A short circuit on the SLC resets the relay. If relay or sounder bases are not used a maximum of 25 addressable devices can be connected ! between Isolator Modules and/or Bases. The module periodically pulses the coil of this relay.M500X The module continuously monitors the circuit connected to terminals 3(–) and 4(+).

These bases also automatically restore the entire loop when the cause of the short circuit is corrected. 3. How an Isolator Base Works If a fault occurs at point “Z”. E. If a fault occurs at point “X”. Isolator bases 1 through 4 will remain normal as isolator base ‘1’ will be served by ‘SLC Out’ and isolator bases ‘4. This is accomplished by isolating that part of the loop containing the short from the remainder of the circuit. Only the device in isolator base 2 ceases to function. devices A through F will remain normal. & C will cease to function and display a trouble warning at the control panel. Devices D.

Madison Ave. One primary surge protector must be used with each SLC wiring pair whenever SLC wiring runs outside the building. Largo. Appendix B: Surge Suppression Introduction There is one primary and there are three secondary surge protectors approved for use with the FACP’s listed in this appendix Primary Surge Protector: • 326-2M TII Station Protector Secondary Surge Protectors: • DTK-2LVLP-F Diversified Technology Group.cdr Installation Mounting is inside the FACP enclosure or in a separate enclosure listed for fire protective signaling use. WA 99019 (800) 727-9119 Note: For detailed information refer to the installation documentation supplied with the unit. Add these additional suppressors in series with the SLC wiring at the building entry/exit. Wiring connected to the surge suppressor output must remain within the building while wiring connected to the surge suppressor input may be routed outside the building as shown below.E. 23123 E.
