Combined smoke and heat detector for use in residential and business premises. With two independent sensors for smoke (optical) and heat (60°C to 65°C). Type of detection (smoke, heat, smoke and heat, smoke or heat) can be set using a jumper. Activation is signaled by an LED and 85dB(A) warning tone (selectable) and a semiconductor alarm output (changeover contact, 60V / max. 0.1A, residual resistance approx. 10 Ohm). Alarm memory function can be selected. Tamper contact (NC) is activated when dismantled. Simple test and muting by pressing the housing. Complies with EN 14604, EN 54-7, EN 54-5/A1. Operating temperature: -10°C to +65°C. Power supply: 9-12V DC (3.5mA idle, 20mA alarm) and 3x 1.5V AA alkaline batteries for self-sufficient alarm in the event of a power failure (included, service life: up to 3 years). Dimensions: D 126 x 50mm. Can be connected to the System 9000 bus via a 9000E1, 9000E16 or 9000EA4 input module (note the module's maximum current consumption). Suitable accessories: Additional base CB20 for accommodating a 9000E1 bus input module.
