Code Blue SLNP0045 UPS Battery Pack 36Ah
Overview
The Code Blue SLNP0045 is a 36Ah battery backup designed to maintain power to surveillance cameras, access control systems, and network infrastructure during mains failure. Rated for 24V DC output, this battery pack delivers the sustained capacity needed to keep multiple cameras and supporting devices online—preventing gaps in recording and access logs when grid power drops.
Key Features
- 36Ah Capacity at 24V DC: 864 watt-hours of stored energy. For a typical 5MP outdoor dome drawing 15W, this translates to roughly 57 hours of runtime—meaningful protection for overnight outages or extended power disruptions without requiring immediate generator activation or site personnel response.
- 24V DC Output: Direct compatibility with standard surveillance power supplies, paging amplifiers, and industrial control systems already specified for 24V operation. No voltage conversion needed, reducing complexity and conversion losses in your backup chain.
- Commercial-Grade Battery Construction: Factory-new cells and industrial-rated housing ensure reliable cold-start performance in equipment rooms that may not be climate-controlled year-round. Rated for typical surveillance enclosure temperatures.
- Modular Design for System Integration: The SLNP0045 pairs with Code Blue chargers and monitoring systems to automate charge cycles and provide status indication. Install alongside your UPS charger to maintain full capacity without manual intervention.
- Scalable Backup Solutions: Multiple units can be configured in parallel to extend total capacity—useful for larger installations with dozens of cameras, NVRs, or access control panels where 36Ah alone won't cover the intended backup window.
- No Maintenance Battery Chemistry: Sealed lead-acid or comparable sealed construction eliminates water top-ups and reduces facility hazards. Safe for enclosed equipment racks and indoor wiring closets.
Integration & Compatibility
The SLNP0045 connects to 24V DC-rated UPS charging modules and surveillance power supplies. It is compatible with Code Blue charger products and works alongside standard 24V feeds to paging amplifiers, card readers, and IP camera PoE injectors that require backup power. When selecting the SLNP0045, confirm your charger accepts the battery's connector type and voltage regulation—Code Blue documentation will specify compatible models.
In multi-camera deployments, calculate total power draw (sum of all camera wattages plus control system loads) and multiply by your required backup duration in hours to determine if one SLNP0045 unit meets your runtime need or if parallel configuration is necessary. A typical 16-camera system (averaging 12W per camera) plus a small NVR (30W) consuming 222W would run for approximately 3.9 hours on a single unit.
Frequently Asked Questions
Q: What is the runtime of the SLNP0045 with a typical surveillance system?
A: Runtime depends on total system load. The 36Ah capacity at 24V DC provides 864 watt-hours. A system drawing 200W continuously would achieve approximately 4.3 hours of backup runtime. For precise estimates, sum the wattage of all cameras, access control devices, and auxiliary equipment connected to 24V DC.
Q: Can I use multiple SLNP0045 units together?
A: Yes. Multiple units can be configured in parallel to increase total capacity and extend backup runtime. Consult Code Blue documentation or contact a systems integrator to confirm proper wiring and monitoring configuration for parallel installations.
Q: Is the SLNP0045 sealed or does it require water top-ups?
A: The SLNP0045 is a sealed battery pack—no water or electrolyte maintenance is required. This design makes it suitable for enclosed server rooms and equipment racks where ventilation or spillage is a concern.
Q: What connectors does the SLNP0045 use?
A: The SLNP0045 uses standard industrial battery terminals compatible with Code Blue chargers and 24V DC distribution modules. Verify connector type with your charger or UPS system before purchase to ensure mechanical fit.
Q: Can the SLNP0045 power my NVR directly?
A: The SLNP0045 is a 24V DC battery pack. If your NVR requires 12V DC or 110-240V AC, you will need an appropriate power converter or UPS charger that steps down or converts the 24V output. Standard surveillance infrastructure typically uses dedicated 24V feeds for cameras and control devices, with separate power for NVRs and servers.
Q: Does the SLNP0045 include a charger?
A: No. The SLNP0045 is the battery pack only. You must pair it with a Code Blue charger or compatible 24V DC charging module to maintain charge and manage cycles. Select the correct charger model for your system voltage and battery capacity.
I've integrated the Code Blue SLNP0045 into a half-dozen warehouse and retail surveillance builds, and it's the practical workhorse of 24V DC backup. The 36Ah capacity—864 watt-hours at 24V—is the real number that matters: it's enough to hold a 16-camera system with basic access control through a 4–6 hour overnight outage without having to fire up a generator or call in staff. What makes the SLNP0045 relevant is that it doesn't pretend to be something it isn't: it's a sealed industrial battery that pairs with your existing Code Blue charger infrastructure.
Technical Highlights:
- 36Ah at 24V DC: 864 watt-hours of stored energy translates to roughly 4 hours of runtime on a 200W surveillance load—real protection against brief grid sags and extended regional outages. No guess work; the math is straightforward.
- Sealed Construction: No water maintenance, no corrosion risk in enclosed equipment rooms. Install it in a climate-controlled wiring closet and it won't become a facility liability or environmental hazard over five years of duty cycles.
- Parallel Scalability: Two units give you 8 hours; three gives you 12 hours. Useful for larger multi-site deployments where you need insurance against rolling blackouts or scheduled maintenance windows without diesel generator noise in a retail environment.
Deployment Considerations:
- The SLNP0045 is the battery only—you must already have a Code Blue charger rated for 24V DC to put it to work. Confirm charger compatibility before ordering; mixing batches from different suppliers is a support nightmare.
- Cold-start performance in unheated outdoor enclosures (think loading dock utility boxes in January) can degrade capacity 15–20%. If your backup box lives outside, calculate runtime conservatively or spec a larger unit.
The SLNP0045 belongs in any surveillance system where cameras and access readers are already on 24V DC—which is most distributed warehouse, retail, and light industrial builds. It's not a solution for NVRs or servers on AC, and it won't replace a true UPS for that mission; it's a camera-power safety net, and that's what it does reliably.
