Figure 4: Example of Detector & MCP Wiring
The zone circuit must be terminated with an end of line resistor with a value of 6.8K (2%
tolerance or better, power rating 1/4W)
4.2
Detector Limitations
1.
Most detectors, with the exception of thermostatic heat detectors, draw a small
monitoring current and this limits the number detectors that can be connected to a
given zone circuit. The total quiescent current of all devices on a zone circuit must be
less than 1.6mA @ 24V to ensure correct operation.
2.
Detectors are
not
intended for use in areas subject to higher than normal corrosive
environments or where hydrogen sulphide or other corrosive gasses may be present.
