1 Overview
Dual-band infrared light detection for fire alarm.
Sensitive to flame from material containing carbon. Suitable for fire happen with
flame at the start.
Addressable (connecting GST fire alarm control panel) and non-addressable
(through relay contact) working modes optional.
Flame-proof. Applicable to either commercial or hazardous industrial areas, such
as explosive Zone 1 and 2, and flammable dust atmosphere.
2 Specification
Operating Voltage:
Loop 24V come from control panel Z1,Z2 terminals(addressable mode
application) or power supply(non-addressable mode application)
24VDC come from 24VDC power supply
Operating Current:
Loop: Standby current≤1mA, alarm current≤1mA, Maximum Consumption
28mW
24VDC: Standby current≤20mA, alarm current≤30mA, Maximum
Consumption:840mW
Classifications:
The detector has 3 classifications. The factory default sensitivity is class 1,
which can be reduced in field using GST handheld programmer.
Detection Distance:
Class 1 : 25m (furthest)
Class 2: 17m
Class 3: 12m
Test Fire: 33cm×33cm n-heptane fire.
The correlation between detection distance and angle is shown in Fig. 1. The
shaded area is detectable.
The semicircle in the figure represents the detection distance in percentage.
