The PS-24-8MC may be connected to any 12V or 24V (FWR or DC) Fire Alarm Control Panel (FACP) by using a Notification Appliance Circuit (NAC) or a “Dry Contact”. Primary applications include NAC expansion (supports ADA requirements) and auxiliary power to support system accessories. This unit provides filtered and regulated 24VDC, 8 Amp up to four (4) Class "B", two (2) Class “A”, or two (2) Class “B” and one (1) Class “A” Notification Appliance Circuits. With the optional plug-in PS-4CA module 101648 the unit supports (4) Class “A” Notification Appliance Circuits. Additionally, an auxiliary power output of 3.5 Amps (disconnected upon AC power loss or an alarm condition) or 200 mAmps (constant) is provided, which can be manually reset. The PS- 24-8MC also contains a battery charger capable of charging up to 20 Amp/Hour (AH) of battery backup. Batteries larger than 12 AH will not fit inside cabinet, use of an external battery cabinet is necessary. Two FACP NAC circuits or two “Dry” contact initiating circuits can be connected to the POWERPATH inputs. These inputs can then be directed to control supervision and power delivery to any combination of the four (4) outputs. Each output is rated at 3.0 Amps (Class "B") or (Class "A") and can be programmed to generate a steady or Code 3 Temporal Horn sound and a strobe output under alarm condition. Total load for the PS-24-8MC NAC circuits shall not exceed 8.0 Amps. The PS-24-8MC under non-alarmed condition provides independent loop supervision for Class “A” and Class “B” FACP NAC circuits. In the event of a loop trouble, the FACP will be notified via the POWERPATH steered input (IN1 or IN2). In addition there are two sets of trouble reporting terminals, one used for AC power loss reporting and the other for all troubles. The AC power loss reporting, on the common trouble terminals, can be delayed for either 30 seconds or 170 minutes. The AC power loss terminals will always report the trouble, 30 seconds after loss of AC power. Wheelock horns/strobes, strobes and horns with synchronizing capability can be utilized with the PS-24-8MC. Audibles can be silenced with only two wires. Additionally, the POWERPATH can provide a temporal coded signal for appliances that can utilize it.

TB5-1, 2 + BAT - 24VDC Battery connection. TB7-1, 2 IN1+,IN1- These terminals connect to the input voltage source (i.e. 12VDC or 24VDC FACP). The FACP will supply a voltage from 8-33V (FWR or DC) at 7mA. During the alarm condition these inputs will cause the designated outputs to drive the notification appliances (designated outputs are set by output DIP switch banks). During Stand-by the PS-24-8MC can report troubles from the designated loop by opening the FACP’s initiation loop. During an alarm condition the PS-24-8MC closes the loop to ensure that the alarm condition will be passed through to the next device on the loop. TB7-3, 4 RET1+, RET1- EOLR is connected on these terminals corresponding to IN1+ and IN1-, or the loop may be continued to other power supplies or appliances before terminating. TB8-1, 2 IN2+, IN2- Same as IN1+, IN1- for corresponding terminals. TB8-5, 4 RET2+, RET2- Same as RET1+, RET1- for corresponding terminals. TB7-5, 6 C “DRY1” NC Dry contacts are used to actuate the designated outputs. Contacts are normally closed and actuate the power supply on contact Open. Designated outputs correspond to IN1+,IN1-. NOTE: Wiring must remain in the same room in conduit. NOTE: FACP NAC circuit cannot energize the power supply by these contacts. NOTE: When these terminals are not in use, a jumper must be connected across them. TB8-5, 6 C “DRY2” NC Operates the same as IN2+,IN2- for corresponding terminals. When these terminals are not in use, a jumper must be connected across them. NOTE: Wiring must remain in the same room in conduit. Indicating appliances are connected to these outputs (See Examples in Operation Section). Each output can supply a maximum load of 3.0 Amps Class "B" or Class "A" and can be individually programmed for TB6-1, 2 +OUT1- Normal Mode, Temporal Mode, IN>OUT SYNC Mode, or WHEELOCK TB6-3, 4 +OUT2- SYNC Mode. The outputs can be configured as four Class "B" circuits, TB6-5, 6 +OUT3- two Class "A" circuits, or two Class "B" and one Class "A" circuits. With TB6-7, 8 +OUT4- the optional PS-4CA module 101648 the unit can provide four Class “A” circuits. Outputs are controlled by a designated input (INPUT 1 or 2) as selected by the DIP switch for that output.
