SSU-MR-701/C/R SPACE AGE

Product Overview

The Space Age Electronics SSU-MR-701/C/R is a single-position, dual-voltage SPDT control relay housed inside a high-visibility, flame-retardant red ABS plastic enclosure. Primarily specified to meet municipal building mandates requiring identifiable red emergency casings, this versatile low-voltage relay provides reliable signal routing for access control panels, security automation, and auxiliary equipment interfaces. The card can be energized by mapping field connections to either a 12VDC or 24VDC control terminal block. Polarity-protected DC inputs safeguard the internal microcircuitry against wiring errors, while a bright, built-in red diagnostic LED shines through the cover window to confirm that the internal coil is successfully energized without opening the enclosure.

Key Features

• Dual-Voltage DC Input: Accepts polarized 12VDC or 24VDC control circuit inputs for low-voltage equipment interfacing.
• Form C Dry Contacts: Outfitted with a single set of SPDT resistive contacts rated for 10A at 120VAC, 7A at 230VAC, and 7A at 28VDC.
• Red ABS 94V-0 Housing: Enclosed in a flame-retardant red plastic cover optimized for high visibility and adherence to local emergency codes.
• Modular Breakaway Design: Substrate features a snap-apart layout, allowing it to be physically separated from multi-position assemblies if needed.
• Visual Status Tracker: Built with an onboard red LED indicator that lights up instantly when the coil shifts to streamline troubleshooting.
• Reverse Polarity Protection: Incorporates polarized DC control terminals to protect the internal microcircuitry against field cross-wiring errors.
• Life Safety Compliance: Formally evaluated and listed under UL Control Unit Accessories alongside strict UUKL Smoke Control system criteria.
