Housing The standby battery’s fiberglass housing is weather- and corrosion-resistant. It is suitable for installation where general purpose equipment is in use. The housing door is hinged on the left side and is secured by two latches on the right side. Four mounting feet are attached to the back of the housing (one at each corner). The mounting feet allow you to install the housing to a vertical surface. A conduit hub on the top of the housing is for external wiring connections.
. The standby battery is shipped with the mounting feet positioned behind the housing. Loosen the screws that secure the feet to the housing, rotate the feet to their mounting position as shown in Figure 2, then tighten the screws. #10 Screw, 4X (user supplied) 3.80 1.75 3/4" Conduit Hub 6.06 Min 7.30 6.85 Max 5.90 4.71 5.90 Figure 2: Outline & Mounting Dimensions 6.

Operation When the standby battery is connected to an RKI Instruments, Inc. controller such as the Beacon 110 (ordered with the optional battery charging capability) or the Beacon 200, the controller maintains a trickle charge on the battery to keep it fully charged. If primary AC power to the controller goes down, the standby battery will power the controller for a limited amount of time until primary power returns. When primary AC power returns, the controller will begin charging the standby battery.
Maintenance This section describes preventive maintenance and troubleshooting procedures. It also includes component replacement procedures and a parts list. Preventive Maintenance Check the standby battery voltage with a volt meter on a quarterly basis and verify that it is fully charged. A fully charged standby battery connected to a Beacon 110 or Beacon 200 that trickle charges it will typically measure between 28 volts and 29 volts.
8. Install each replacement battery. Line up the locking strip on the back of the battery with the strip on the inside back of the housing and push the battery firmly onto the strip.
