PIX inputs and
outputs
PIX outputs
PIX outputs comprise four relay contacts controlled by the alarm board and
MCUF. The relays have multiple contacts, some normally open and some
normally closed. The contacts are rated for 1 A at 30 V. The contacts may be
used for control of external equipment such as fans or audible alarms.
PIX inputs
PIX inputs comprise 16 connections to external sensors. These inputs report
alarms to the BSC, via the alarm board and MCUF, which forwards the alarms to
the OMC-R. The end-user supplies the external sensors. Each sensor connects
across an opto-coupled pair of PIX inputs (eight per PIX connector).
All sensors must be dry-contact type with the following specification:
5 kohms or greater across sense inputs for logic 1 (PIX opto-coupler off).
500 ohms or less across sense inputs for logic 0 (PIX opto-coupler on).
Table 3-11 shows PIX0 connections and Table 3-12 shows PIX1 connections.
