SNAC-4 SUPPLEMENTARY NOTIFICATION APPLIANCE CIRCUIT PANEL DESCRIPTION The Supplementary Notification Appliance Circuit Panel (SNAC-4) provides four, (4), 24 VDC Class A, Style Z or Class B, Style Y notification appliance circuits, with a total capacity of 6 amperes. These circuits may be activated in groups of two or four by connection to normally open dry contacts or existing Class A or Class B notification appliance circuits with operating voltages ranging from 12 to 32 VDC. The panel may be used to replace earlier versions of the SNAC family. Either non-coded operation, coded operation, temporal pattern or a combination is possible. The SNAC-4 operates from 120/240 VAC input and contains its own battery charger, capable of maintaining a set of 7 A/H batteries. It is supervised for ground fault, overcurrent, open circuits and low battery conditions. The regulated power supply allows the SNAC-4 to be compatible with any Listed, nominal 24 VDC notification appliances. Ground fault, battery and circuit trouble conditions in the SNAC-4 automatically open the notification appliance circuit used to activate the SNAC-4, transmitting a trouble signal to the main fire alarm control panel. The ground fault detection circuit may be disabled. The unit contains a set of dry, jumper programmable (N/O or N/C) trouble actuated contacts, rated 1 amp. @ 24 VDC (resistive). Transfer of these contacts for AC power failure is delayed for a period of ten (10) hours. This delay feature may be disabled. A power limited, non-resettable auxiliary power output of 1.75 amps is available if the panel is arranged via jumper to disconnect itself from the batteries during AC power failure. An output of 0.150 amp. is available when the SNAC-4 is connected to a control panel requiring 24 hr. standby. The current is reduced to .050 amp. when 60 hour standby is required.
