AL802 WAL NAC Power Extender (8 A)

www.boschsecurity.com

The AL802 WAL NAC Power Extender is a cost effective 8 A remote power supply and battery charger that can be connected to any 12 VDC or 24 VDC fire alarm control panel (FACP). Its primary

application is to provide notification appliance circuit (NAC) expansion support that meets Americans with Disabilities Act (ADA) requirements. It can also be used to provide auxiliary power to support system accessories.

Functions

Battery Backup

There is a built in charger for sealed lead acid or gel type batteries. The enclosure has room for two

12 VDC, 12 Ah batteries. If AC fails, there is automatic switchover (with zero voltage drop on switchover) to standby battery.

Inputs

Power input is 115 VAC, 60 Hz, 1.45 A. There are two normally closed (NC) dry contact trigger inputs. The unit is equipped for two Class A or two Class B FACP inputs.

uTwo (2) Class A or four (4) Class B outputs

uInput to Output Follower mode maintains synchronization of NAC devices

uAC Fail, Low Battery, and Battery Presence supervision

uLEDs indicate prior fault on one or more signaling circuit outputs

uOne auxiliary power output (1 A supply current) with battery backup

NAC Loop Supervision

In non alarm conditions, independent loop supervision for Class A and/or Class B FACP NACs is provided. In the event of a loop trouble, the FACP is notified by the steered input (input 1 or input 2). In addition, there are common trouble output terminals (NC, C, NO) that are used to indicate general loop or system trouble. A common trouble input is provided for optional normally closed (NC) devices to report trouble to the FACP. Two FACP signaling outputs can be employed and directed to control supervision and power delivery to any combination of the four outputs. The unit also has Loop Output trouble memory indication to help identify troublesome sporadic problems.

Outputs

The AL802 WAL delivers electronically regulated and filtered 12 V or 24 V power to Class B or Class A NAC loop circuits. Additionally, a separate 1.0 A auxiliary output for four wire smoke detectors is available. The 8 A maximum alarm current can be divided among the four outputs for powering NAC devices. Each output is rated at 2.5 A maximum. The outputs are Class 2 rated power limited outputs with auto reset thermal and short-circuit protection.

Output Programming

Each output can be independently programmed for Steady, Temporal Code 3, or Strobe synchronization. All outputs can be programmed for Input to Output Follower mode.

Paralleling Outputs

An individual output of 4 A can be obtained by paralleling two outputs.

Horn and Strobe Synchronization

The two-wire synchronization mode works with the Gentex Commander GOS Sync Mode 3, 4 and ST/HS series, the System Sensor SpectrAlert series of horns, strobes, and horn strobe combinations, and Cooper Wheelock horns, strobes, and horn strobe combinations to provide a means of synchronizing the temporal-coded horns, synchronizing the flash timing of the strobe, and silencing the horns of the horn strobe combination over a two-wire circuit while leaving the strobes active.

Notice

The AL802 WAL will synchronize only the horns, horn strobes and strobes that contain synchronization capability.
