The DS-K7PEB’s fire‑resistant housing and sand‑blast finish are important for devices expected to be used under emergency conditions. The housing helps preserve structural integrity and visibility in environments where heat, smoke or rough handling may occur. The mechanical break‑glass action is a proven, intuitive method for initiating emergency door release—users can rapidly understand the action required even under stress.
The NO / NC / COM outputs make the unit highly flexible. Whether you need a normally open or normally closed contact for an alarm panel, maglock, or a door controller, the DS-K7PEB supports common wiring arrangements and allows installers to adapt the device to the control logic in place. The electrical rating of 3 A at 36 VDC covers most small to medium door release circuits and ensures the unit can directly drive many common loads or interface reliably with relays and controllers.
Compact dimensions and low weight simplify placement and installation. This makes the device suitable for narrow corridors and confined mounting spaces where larger emergency stations might not fit, while still providing the user with a clear, tactile actuation point.
Use cases and scenarios where the DS-K7PEB excels
- Commercial office buildings:Positioned at exit doors and routes of egress, this break‑glass unit provides a straightforward manual release for employees and visitors during power failures or alarm events.
- Public facilities:Libraries, community centres and municipal buildings benefit from a conspicuous and reliable release point that integrates with existing alarm and access control equipment.
- Retail and hospitality:Back‑of‑house exits, emergency stairwells and staff doors can use the DS-K7PEB to meet regulatory requirements for emergency egress without adding bulk or complexity.
- Small industrial sites:Light manufacturing or warehouse facilities that use maglocks or electrically controlled doors can deploy this unit where a compact, durable emergency release is needed.
- Installer and contractor specifications:Where a dependable, standards‑friendly break‑glass unit is required on a project, the DS-K7PEB provides consistency of form and function and integrates with common control panels and maglocks.
Proper installation is essential. The DS-K7PEB should be mounted on a wall near the exit point in accordance with local building and fire codes. Wiring and electrical integration must follow national and local wiring regulations, and installers should confirm CE/UKCA markings and any regional approvals on the product datasheet or labels. Because the unit is rated to 3 A at 36 VDC, do not use it to directly drive loads that exceed this rating; instead, use the unit to trigger an intermediary relay or interface device when higher currents are required. Regular testing and maintenance should be performed where mandated by local fire safety legislation.
Comparisons with similar products on the market
The break‑glass emergency release category includes several design approaches: purely mechanical devices, semi‑electronic units with tamper covers, and fully electronic egress buttons with reset features. Here’s how the DS-K7PEB compares across a few common dimensions:
The DS-K7PEB emphasizes mechanical simplicity—an advantage in environments where a low‑failure, intuitive action is preferred. Compared with fully electronic exit buttons or touchless egress sensors, the mechanical break‑glass is less dependent on power for actuation and provides an unmistakable manual action for users. This can be preferable in emergency situations where power or communication may be compromised.
Many competitors offer units with just a normally open contact or with a built‑in alarm. The DS-K7PEB’s NO / NC / COM contacts give installers greater flexibility to wire the unit to different types of alarm panels, door controllers and maglocks without needing additional adapters. For installations that require a dedicated alarm siren or local sounder connected directly to the break‑glass activation, some alternative products include integrated sounders—however, the DS-K7PEB’s approach allows system designers to choose the most appropriate alarm peripherals for their application.
The fire‑resistant housing and sand‑blast finish make the DS-K7PEB a robust option. Some competing units prioritize aesthetic design with smooth plastic housings or larger reset covers; those may look sleeker in high‑end settings but can trade off fire performance or scratch resistance. The availability of green and red colour options and optional transparent cover accessories with the DS-K7PEB helps it balance visibility and site aesthetics.
With a suggested price of $29.99 and an economical construction, the DS-K7PEB offers an accessible entry point for projects that need multiple emergency release points. Higher‑end units with additional electronics, integrated alarms or rugged ingress protection will cost more; the DS-K7PEB’s value comes from providing essential emergency release function and wiring flexibility at a relatively low cost.

Conclusion: Why the DS-K7PEB is a strong choice
The Hikvision DS-K7PEB Emergency Break‑Glass Unit (Green) is a practical, cost‑effective choice for many emergency egress needs. Its combination of a fire‑resistant housing, mechanical break‑glass action, and NO/NC/COM outputs provides both durability and installation flexibility. The compact form factor and modest electrical rating make it well suited to commercial, public and light industrial settings, while its competitive price point supports projects with multiple required exits without escalating costs.
When selecting an emergency break‑glass unit, consider the DS-K7PEB if you need a straightforward, reliable mechanical release that integrates cleanly with existing access control or alarm panels, and where adherence to local fire safety standards is maintained through proper installation and testing. For sites that require integrated alarms, higher current capability or specific environmental protection ratings, you may want to evaluate higher‑specification products; however, for many standard installations, the DS-K7PEB represents a balanced, dependable solution.
