I’ve always loved the sound of the EH series alarms! I myself have an EHS-EL1 in my collection. It would be pretty cool if you did a test with all System Sensor MASS devices.
That horn strobe might be the same model in my school. For clarification, my school uses T-bars for activation, plus Simplex strobes and a Wheelock model that may be identical to the horn strobe you have up for notification appliances.
