SEC-H-600 SECURITY CONTROLLER
95-7759—07
28
Providing that the backup battery has tested good, upon loss of primary power the system operates from this backup battery
power until the charge level of the onboard NiMH battery pack reaches 0. Note that both batteries discharge in parallel. However,
as the sealed lead-acid backup battery capacity is much greater, the NiMH battery pack discharges much slower than if these
backup battery(ies) were bad or not present.
NOTE: If the backup battery test was “bad,” upon loss of primary power, the Security Controller performs an immediate shut-
down, backing up data and powering off (including attached readers, expansion modules).
You should replace the sealed lead-acid backup battery(ies) approximately every three years, or more often if the unit is in a high
temperature environment.
NiMH battery pack
A custom 10-cell NiMH (nickel metal hydride) battery pack is mounted onto the unit, under the cover—see Fig. 15 on page 26.
This battery allows the Security Controller to continue station operation (only) through very short power bumps, meaning a few
seconds in duration. If a longer outage, the NiMH battery provides enough run time for the unit to backup data and then
shutdown. Typically, this process takes about one minute. Shutdown occurs automatically, after data is backed up to on-board
flash memory.
Upon startup (boot), a test of the NiMH battery is performed. A system alarm is generated if the NiMH battery voltage level is
found to be bad. A charge is also initiated upon startup, which lasts from 3 hours minimum, and can range up to 18 hours if the
battery is completely discharged. During this NiMH battery charge period, neither the NiMH battery or the Backup Battery is
tested. After the startup NiMH charge period, a periodic test of
both
batteries occurs, and the appropriate battery alarm is
generated is either battery is found to be bad.
NOTE: If the last NiMH battery test was “bad,” upon loss of primary power the Security Controller performs an immediate shut-
down, backing up data and powering off (including attached readers, and expansion modules).
A NiMH battery characteristic is to lose charge if not left in charge mode (trickle charge). Leaving the battery uncon-
nected, or in the unit powered off will cause the battery to fully discharge in a matter of weeks. Note that in the case of a
new Security Controller, it ships from the factory with a completely discharged battery. Therefore, allow at least 18 hours
for the battery to charge if it has not been in a powered unit.
You should replace the NiMH battery pack approximately every three years, or more often if the unit is in a high temperature
environment. For more information on the use and replacement of the NiMH battery, refer to the “Required NiMH Battery
UL REQUIREMENTS
This section provides requirements for a UL 294 Listed system. Failure to install the Security Controller and its expansion
modules in accordance with these instructions voids the listing mark of Underwriters Laboratories, Inc.
NOTE: This product is not Listed to UL 1076. For UL Listed systems, this product should not be programmed or configured for
burglar alarm functions.
• Battery-backed Power Supplies
Mounting and Wiring
1.
The Security Controller must be mounted in a WEBs-AX Security Enclosure, model SEC-ENC-H-1 or SEC-ENC-H-2,
which provides an integral 15Vdc power supply (NPB-PWR-UN-H) to power the unit. Expansion modules must also be
mounted in WEBs-AX Security Enclosures, either (the same or different) enclosure, depending on number and location of
expansion modules needed.
2.
Enclosures must be mounted inside the secured area.
3.
Grounding must be in accordance with Article 250 of the National Electrical Code.
