(d) Alarm verification by point on SLC’s.
(e) At least 4 distinct Day/Night automatic smoke sensor sensitivity adjustments.
(f) One man walk test with optional notification appliance testing.
(g) 600-event history buffer.
C. Distributed Processing - Central Microprocessor
(1) The system should employ a system of distributed processing, to increase system reliability. Each subassembly mounted remotely from the main control system shall include a microprocessor and be supervised by the central microprocessor. The central microprocessor shall monitor, communicate to, and control and monitor all external devices. All custom operating parameters for the system shall be stored in non-volatile memory to prevent loss during power outages. A real time clock shall be provided to denote actual time of occurrence of system events for the display, history buffers and external reporting devices.
D. DISPLAY
(1) An 80-character backlit LCD shall annunciate system conditions and program system operating parameters.
(2) Nine status LEDs, AC Power, Alarm, Supervisory, Trouble, Alarm Silence, Supervisory Silence, Trouble Silence, Offline, and Test Mode shall be provided.
(3) The display unit shall provide a 16 keypad with tactile feel membrane switches that provide operational feedback. Keys shall be dedicated to System Reset, System Silence, Drill, Program Mode, System Status, System Test, and Print Mode. The keypad shall be used to provide all control and programming functions for the system. Programmable Function Keys shall provide for up to 5 input groups from the panel front.
E. Signaling Line Circuits (SLC)
(1) Each SLC shall provide power and communication with up to 126 analog or addressable devices. The basic system shall consist of two (2) SLCs (252 devices total) with expansion to twelve (12) SLCs (1512 devices total). Each SLC shall be capable of meeting the wiring requirements of NFPA 72, Style 4, 6 or 7 without add-on module. The panel shall provide the ability to remotely mount the SLC loops up to 6,000 feet from the main control system in a UL 864 listed enclosure.
(2) Each SLC shall communicate to resident devices using a completely digital communication method to provide a more reliable, noise-immune communication system. All communication between an addressable device or sensor shall use a validation method, to validate the integrity of each message. Systems that use a hybrid analog and digital communication scheme will not meet the requirements of this section.
(3) Each SLC shall be capable of communication over standard wire (no twisted pair or shielding required).
(4) The control system shall meet the requirements of NFPA 72 as a calibrated smoke sensitivity device.
F. Enclosures
(1) The system shall be housed in a small-footprint enclosure with dimensions not to exceed 25.5" X 14.5" X 4.0".
(2) The enclosure shall be capable of surface or semi-flush mounting without requiring additional hardware.
(3) The enclosure shall be painted red with a corrosion-protective, hardened finish.
G. Power Supplies
(1) The power supply shall operate upon either 120 VAC or 240 VAC, 50/60 Hertz without adjustment, and shall provide all power necessary to operate the control system.
(2) The power supply shall provide at least 5.75 amps of power for use on notification appliance circuits or auxiliary power circuits.
(3) Each power supply shall provide battery charger capacity to sufficiently recharge a depleted set of up to 60 AH batteries in a remote enclosure within 48 hours.
(4) Additional power will be available from a UL listed 24VDC-power supply, the IPB-3.
