ZP3-ECU Extinguishing Control Unit Installation and Commissioning Manual
Additional information
When using the ECU with a ZP3 Fire Alarm Control Panel, be aware of the
following.
Planner and Maestro graphics software
When configuring Planner panel programming package or Maestro graphics
package for use with the ECU, the LOOP A address is denoted by "ECU" and the
LOOP B address is denoted by "LRY".
In the Maestro graphics package, the LOOP A address reports the ECU status,
and therefore it is not necessary to allow for an icon for the "LRY" LOOP B
address.
Operation
There is a cosmetic software "bug" in the ZP3 Fire Alarm Control Panel. If the
LOOP B address of the ECU is activated before the LOOP A address, the fire
panel reports "TRIGGR". The ECU is only "triggered" when both the LOOP A and
LOOP B addresses are activated by fire conditions. If the LOOP A address is
activated first then the "bug" is not apparent. This "bug" in no way affects the
correct operation of the ECU.
