PIR/BMS Plug-in Card (2-Way)
– PIR-0-10-3041-212 (TPCA029) (Optional)
Although the PIR card is designed as a two-way card, when used on the SZAOV panel only
one side of PIR and BMS connectors can be used. This means only one PIR can be fitted in
the system.
PIR 1/PIR 2 (+ -)
The PIR input is available to monitor a typical security type PIR with N/C alarm and tamper
contacts. The PIR requires a 12VDC supply, taken from the boards 12V output. The input
requires a 10KΩ impedance to trigger, with a 6K8Ω 5% 0.25W EOL resistor. Monitoring
current limit is 14mA, unfused.
When operated, the PIR alarm prevents the vent from closing to guard against entrapment
injury. The PIR should be mounted in accordance with the manufacturer’s instructions, to
detect any presence in the vicinity of the entrapment risk.
BMS 1/BMS 2 (0V IN OUT)
Building Management System control interface, using 0-10 volt proportional control signals:
•
0V
– Common 0V output. This is 0 volts common reference for 0-10V input and
output
•
IN
– Positional voltage input. Accepts 0-10 volt (DC) signal in 1 volt steps per 10% of
motor time. Vent position is determined by running time, which by default is 60
seconds, i.e. 10% = 6 seconds running time, 50% = 30 seconds etc. Max input is
10VDC, with 75kΩ impedance.
•
OUT
– Positional voltage output. This output represents the position of the vent in
10% steps of motor run time. Provides feed-back of the 0-10V input status and vent
positional information. Max output is 10VDC 2mA. Max 20KΩ load and 680R
impedance.
RAIN (+ -)
Signal input from wind/rain sensors. Typically, a wind/rain sensor will have a closing contact
alarm signal and may require a 24V supply. The input requires a 2K7Ω impedance to trigger,
with a 6K8Ω 5%0.25W EOL resistor. Monitoring current limit is 14mA, unfused. Any one of
the wind/rain sensors can close a manually opened vent but will not override an alarm signal
input.
