The SLC communicates with smoke detectors and other input and output modules over a twisted­pair wire. The SLC wiring can be configured as Style 4 (Class B) or Style 6 (Class A). Any combination of detectors and modules can be mixed on the SLC. Each detector is independently configurable to incorpo­ rate an alarm verification feature that reduces the number of "unwanted" alarms. Each detector may have a varying sensitiv­ ity setting that is based upon manual settings or changed in reaction to events or a time or weekly schedule. The ALT­7 polls each analog addressable device and reports their Alarm, Trouble, or Normal status to the COM­2 Communi­ cations Card located in the DAB­7 Motherboard of the DAN­7 Cabinet. Device status is then transmitted over the riser net­ work wires to the Fire Command Center (FCC) and other nodes in the system. Dirty detectors can be sensed and their status reported as a Trouble Maintenance condition. A 1.5A @ 24VDC auxiliary power output provides power for remote modules that require power in addition to the communications loop. Optional Degrade Mode programming allows input and output devices to continue to operate in the event of a failure of the microproces­ sor on the COM­2 card of the DAN­7. The Firefighter/Warden Telephone circuits can be configured as 4 Style Y (Class B) circuits or 2 Style Z (Class A) circuits. Each circuit can communicate with Firefighter Phone Jacks or up to three 2­wire Warden Stations. The telephone circuits are moni­ tored and controlled by the COM­2 Communications card in the DAN­7. When a Firefighter's phone is plugged into a jack or a handset "calls­in", a call­in signal is transmitted to Fire Com­ mand Center (FCC). The operator pushes a switch on a Display Control Module at the FCC to establish a communication ses­ sion between the telephone handset at the FCC and the "called­ in" phone. The FCC operator can communicate with up to five simultaneous Firefighter/W arden phones. Call progress tones are presented through the phone handset. When a phone "calls­ in", a ring­tone can be heard in the earpiece. If a call cannot be processed, a busy tone will be heard. Once the call is in progress, tones are removed. Activation indicators on the module indicate which circuits are in use and turned on. Upon command of the operator at the FCC, a Warden Phone or a handset plugged into a Firefighter Phone Jack can be enabled to page selected areas of the facility. A ground fault on any circuit is automatically detected, and a technician­invoked ground fault isolation test helps in the iden­ tification of the circuit that is presenting the ground fault condi­ tion.
Installation Application The ALT­7 is used to communicate to analog addressable smoke detectors and input/output modules, as well as to communicate with Firefighter Telephone Jacks and 2­wire Warden Phone Sta­ tions. Up to five phones can communicate at one time in the LSN 2000 system. The ALT­7 Analog Loop and Telephone Module installs in any of the eight Option Slots in a DAB­7 Motherboard of a DAN­7 Cabi­ net. Each motherboard is software programmable to allow up to 8 ALT­7 option cards.

Engineering Specifications The ALT­7 Analog Loop and Telephone Module shall contain one SLC capable of communicating to compatible Firecom Analog Addressable Devices (See Compatible Devices ). The SLC shall communicate with up to 126 detectors and/or modules. Any combination of devices shall be allowed on the loop. The ALT­7 shall also contain 4 Style Y (Class B) or 2 Style Z (Class A) telephone circuits. The selection of Style Y or Style Z shall be field selectable. Each phone circuit shall be capable of communicating to Firefighter Phone Jacks or 2­wire Warden Stations with confirmation LED. A ring tone shall be generated on all activated circuits until communications with the Fire Command Center has been established. Indicators on the ALT­7 shall denote circuits with active communication links. The DAB­7 Motherboard of a DAN­7 shall allow up to eight ALT­7 modules to be installed into its option slots.
