The PMB-AUX and PMB-AUX-RTO are auxiliary power supplies for touchscreen fire alarm control panels. The units are identical in functionality,
but differ in mounting availability. The PMB-AUX mounts in a CAB-5 Series enclosure while the PMB-AUX-RTO mounts in a CAB-4 Series enclo-
sure. They both feature 3 amps of power in standby/8.5 amps of power in alarm, four (4) power-limited NAC outputs which can be configured for
either Class A or Class B wiring, two (2) 24VDC auxiliary power outputs, and a remote sync input. One auxiliary power output, AUX1, can be config-
ured for either class A or class B wiring. A maximum of two (2) PMB-AUX(-RTO) power supplies can be installed in an enclosure in addition to the
FACP (fire alarm control panel). If more than five (5) loop cards are installed in the system, a PMB-AUX(-RTO) power supply is required, and if ten
(10) loop cards are installed in the system, two (2) PMB-AUX(-RTO) power supplies are required, for battery charging and alarm load.

- Page 3 3.2 PMB-AUX The PMB-AUX Power supply comes pre-installed on a chassis for easy installation in a CAB-5 series cabinet. Mount the chassis to the backbox by aligning the two mounting tabs with the slots in the backbox, then position the two mounting hole tabs over the studs with nuts located in the upper portion of the backbox.
- Page 4 Mount the chassis into the second row of the backbox. Align the center hole on the edge of the chassis with the studs on the backbox and secure with two supplied #8 keps nuts. (The FACP should be mounted in the top row.) If installing a second PMB-AUX-RTO, install the chassis in the third row of the cabinet using the top mounting holes on the edge of the chassis.
