INSTALLING THE TYPE 2 ACPSU.
The Type 2 PSU (ACPSU) consists of an AC PSU Unit with standby batteries
and generates power fail alarms that are passed to the CT.
STEP PROCEDURE
PSU (Type 2) Positioning and Securing
1. Confirm the position of the ACPSU, allow for adequate ventilation and service
access.
2. Note: The life of the batteries within the ACPSU will be increased in a low
temperature, but standby time will be improved by a warm environment. Ideally the
location should be cool, as the electronics within the unit will keep it warm enough
to ensure a good standby period.
