STI EM243608A1 Metal Protective Cabinet with AC/Heater
Overview
The EM243608A1 is a UL Type 4 metal protective cabinet with integrated AC and heating designed to shield fire alarm control panels and high-value electronics from temperature extremes, vandalism, dust, and corrosive environments. The enclosure mounts horizontally to standard wall surfaces and protects equipment up to 21″ L × 33″ H × 6″ D with adequate airflow. The robust metal construction with durable corrosion-resistant finish handles both accidental and intentional damage — a critical layer when your control panel sits in a public or exposed area (lobbies, building exteriors, loading docks). Unlike competitor cabinets, this unit offers an optional transparent window for quick visual identification of the protected equipment without opening the enclosure.
Compatibility
This cabinet fits standard fire alarm control panels, security system processors, and electronic devices requiring environmental protection and thermal regulation. The horizontal mount configuration integrates into wall-mounted access control and fire safety installations where space is tight or where the protected unit must remain flush against vertical surfaces. Verify your internal equipment dimensions (max 21″ L × 33″ H × 6″ D) and confirm your mounting wall can support the assembled cabinet weight and AC/heater unit load before installation.
Installation Notes
The cabinet includes a mounting plate for secure wall attachment. Two 1/4″ quarter-turn latches prevent unauthorized entry — standard for UL Type 4 access control enclosures. The AC/heating unit mounts externally to minimize internal intrusion and preserve equipment clearance. Ensure adequate electrical supply for the integrated climate system and verify ventilation pathways are unobstructed. The durable finish protects against corrosion, reducing maintenance cycles in harsh or humid environments.
