PS861 Series power supplies are designed for electromagnetic locks and electric strikes on single door applications. The output power is field selectable for either 24VDC @ 1 ampere or 12VDC @ 2 ampere. Standard input 120VAC @ 0.6 ampere and 240VAC @ 0.3 ampere available. Terminal block will accept up to 14 gauge stranded wire. Enclosure is gray with 1 hinged cover and constructed of heavy 19 gauge steel. Six 1/2" (13mm) knockout holes are provided for conduit connection. Options include keylock cover and sealed lead acid battery pack. The pair of batteries will provide back-up power for three hours at full load or seven hours at half load. Batteries will automatically recharge when failed power is restored.

PS873 Series power supplies are designed to operate a wide variety of electrical products including EL (electric latch retraction) exit devices. The regulated output power is field selectable for either 24VDC @ 2 ampere or 12VDC @ 4 ampere. Standard input 120VAC @ 1.0 ampere or 240VAC @ 0.5 ampere available. Enclosure is gray with a hinged cover and constructed of heavy 19 gauge steel. Five knock-out holes are provided for conduit connection. Terminal block will accept up to 14 gauge wire. The PS873 can be ordered with three standard options: key lock secures the cover to eliminate tampering and provides safety; battery backup provides two hours backup power at full load during a A.C. power failure; fire Alarm provides input for a normally closed fire alarm contact. When the fire alarm contact is “open”, power to locks or other component is removed. Restoring power is field selectable for automatic or manual.

PS873-DE, Delayed Egress function ideal for use with electromagnetic locks, will operate two zones simultaneously. To operate two separate zones, a second 873-DE card is required. UL listed component, when used as part of a Von Duprin delayed egress system.

Field Installed Circuit Cards:
871-2 Two Zone controller provides two inputs and two outputs. Will operate two EL exit devices.
873-AL Alarm function monitors 1 or 2 zones and provides alarm output, upon detecting a door in the open position. Delayed alarming is selectable from 5 to 75 seconds.
873-AO Auto Operator function coordinates the release of one or two locks and signals an auto-operator to open a door. Signaling the auto operator can be performed in two methods; by receiving a signal from a monitoring switch that the lock is unlatched, or upon expiration of a time delay triggered by a “RX” type input switch.
873-SI Security/Safety Interlock provide interlock function for two zones. When combined with a second 873-SI card, the inter-locking of groups are available in two, three or four zones. Safety interlock is available, consult jlm for additional information.
873-2TD-F Two Zone controller with Time Delay and Fire Alarm combines two zone controller, field selectable time delay from 0 to 75 seconds, in intervals of 5 seconds, and a fire alarm input which can be field selected for automatic or manual reset.
873-4TD Four Zone controller with Time Delay provides four inputs and four outputs with time delay. Time delay is field selectable from 0 to 75 seconds, in intervals of 5 seconds.
873-AC Access Control provides supervision of one zone using an electromagnetic lock. Input signals required are: access control contact, motion detector contact, and motion detector override contact. FA, Fire Alarm option is required.
