1 General
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.
1.1 Hardware Kit
The PMB ships with all hardware necessary for installation.
• two (2) #8 keps nuts
• one (1) 22” wired cable for CLP bus connection
• six (6) terminal block plugs

• No charger
• Low (7-26AH)
• Medium (33-55AH)
• High (100AH)
3 Installation
The main FACP assembly should be mounted in the top row of the cabinet. Due to cable length restrictions, the PMB-AUX(-RTO) must be mounted in
the second position of the backbox. If installing two PMB-AUX(-RTO) power supplies, the second unit must be mounted in the third position. A max-
imum of two PMB-AUX(-RTO) units is allowed
Wiring methods used shall be in accordance with Standard for Installation and Classification of Burglar and Holdup Alarm Systems, UL 681.
3.1 Requirements
• Installations are to be indoors only, in dry locations, protected from rain, water, and rapid changes in temperature that could cause condensation.
• Equipment must be securely mounted on rigid, permanent walls.
• Operating temperature shall not exceed the range of 32° to 120° F (0 to 49° C).
• Operating humidity not to exceed 93% +/- 2% non-condensing at 100° F (38° C).
• Adequate space must be available around the installation to allow easy access for operation and servicing.
• All sub-assemblies and components are to be located in compliance with local and national codes.
• All installation field wiring shall be in compliance with local and national codes.
!
WARNING: HIGH VOLTAGE PRESENT
REMOVE ALL SOURCES OF POWER BEFORE SERVICING, REMOVING, OR INSTALLING ANY UNITS. ENSURE TO
INSTALL THE SNAP-ON COVER OVER TB1 AFTER WIRING.
!
CAUTION: STATIC SENSITIVE EQUIPMENT
THE CIRCUIT BOARD CONTAINS STATIC-SENSITIVE COMPONENTS. ALWAYS USE PROPER GROUNDING DEVICES
SUCH AS A WRIST STRAP BEFORE HANDLING ANY BOARDS SO THAT STATIC CHARGES ARE REMOVED FROM THE
BODY. USE STATIC SUPPRESSIVE PACKAGING TO PROTECT ELECTRONIC ASSEMBLIES.

3.2 PMB-AUX
The PMB-AUX Power supply comes pre-installed on a chassis for easy installation in a CAB-5 series cabinet.
1. 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.
2. Slide the tabs located on the bottom of the chassis into the mounting slots in the backbox by pressing the chassis down.
3. Secure the chassis to the backbox. Fasten the two supplied #8 keps nuts over the mounting holes at the top.

3.3 PMB-AUX-RTO
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 shouldbe 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. Refer to Figure 3below for details.
