Grinnell IXA-500CMA Detector Module

The Grinnell IXA-500CMA is an addressable contact-monitoring module for Grinnell/Autocall fire-alarm systems, designed to mount to a standard 2-gang box and supervise a dry contact on the signaling circuit. It operates on 28 VDC with a signaling current specification of up to 0.18 mA, making it a low-power supervisory device within an addressable loop. The unit uses a polycarbonate ABS alloy housing and measures 4.9 inches high by 4.9 inches wide by 1 inch deep, with an operating temperature range of 32°F to 120°F and 85% noncondensing humidity, suitable for installation in typical fire-system enclosures. An end-of-line resistor pack (10 × 619 Ω) is specified for use with P/N 976081 (IXA-501CM) and the IXA-500CMA is cataloged as 976092, reflecting its role as an addressable contact monitor within Autocall systems.
