ZP3 Fire Control Panel Installation, Commissioning, and Maintenance Manual
• 70–100: Values in this range indicate an intrinsically safe (EX) device. The
norm for intrinsically safe devices is 84, which indicates best calibration.
• 135–163: The norm for ZR and ZX devices is 152.
• 197–226: Values in this range indicate a healthy non-intrinsically safe device
(ZP). The norm for devices is 213, which indicates best calibration. If a device
falls outside the range 205 to 218 then it should be recalibrated.
Values falling outside the above ranges indicate a very poorly calibrated or
unhealthy device. The panel treats all such devices as invalid. If occurring on
multiple devices, a wiring fault may be suspected.
Readings two (polling group) and three (device type) together with reading one
(reference group) identify the type of the device. The device types indicated by
combinations of the three readings are provided in Table 52 below.
The Code column gives a three-digit identifier for the device, each digit derived
from the values of the device type readings. Some intrinsically safe devices may
have the same code as standard devices but are distinguished by their reference
group reading (reading 1).
