STI STI-SA5500-G Select-Alert Siren/Strobe Controller
Overview
The STI-SA5500-G is a dedicated siren and strobe controller designed to manage audible and visual alert signals in access control and emergency notification systems. Powered by 9VDC (or external 12–24V supply), it handles up to 32 concurrent users and supports independent timing control for siren and strobe outputs—15 seconds, 30 seconds, 60 seconds, or continuous activation. The unit houses ten high-intensity LEDs and offers 32 user-selectable siren tones at either 100 dB or 85 dB output, allowing facility operators to tailor alert intensity to space size and occupancy without triggering unnecessary alarm fatigue across large deployments.
Compatibility
The STI-SA5500-G integrates directly with STI Select-Alert siren and strobe systems. It works as a cabinet alert, door alert, or networked burglar alert when linked with push buttons, switches, or access control panels. The unit outputs one Form C dry relay contact (12VDC, 50mA rated)—suitable for triggering door strikes, auxiliary relays, or other low-voltage signaling devices in standard security integrations. Available lens colors (amber, green, blue, red, white) allow visual coordination across multi-zone facilities.
Installation Notes
Mounting options accommodate wall, cabinet, or surface installations. The controller includes a tamper switch that triggers an alert when the unit is removed—a critical feature for facilities requiring evidence of tampering attempts. Operating temperature range is 32°F to 120°F; indoor use only. Polycarbonate construction provides durability in typical office and commercial environments. A low-battery indicator alerts operators when power is depleted, supporting maintenance scheduling in battery-powered deployments.
