Audio Amplifiers
Signature Series amplifiers are high-effi-
ciency switch mode audio amplifiers
available in 30 and 50 watt sizes. Amplifi-
ers have two input channels supporting
dual channel or single channel audio ap-
plications. Signature amplifiers are ide-
ally suited for distributed audio applica-
tions and small centrally banked applications. The audio output is configurable as 25VRMS or 70VRMS in Class B or Class
A wiring configurations. Speakers can connect directly to the output of the amplifier or the amplifier output can run
as an audio riser to Signature modules where speaker zone selection is made. Each amplifier has a built-in 1kHz tone
generator and provision for a back up amplifier. On-board status LEDs provide quick visual indication of amplifier
status.

Auxiliary Power Supplies
The SIGA-APS is a switch-mode power supply that pro-
vides additional power for any fire alarm control panel
that includes a Signature Data Circuit. The SIGA-APS
mounts with local fire alarm equipment or may be
mounted remotely to supply power to signaling devices,
amplifiers or system equipment. The power supply com-
municates with the main control panel over the Signa-
ture Data Circuit. This eliminates the need to mount additional monitoring equipment when the power supply is
mounted remote from the main control panel.
