NORMALLY OPEN / NORMALLY CLOSED DRY CONTACTS
Dry contact sources consist of alarm relays or switches that are isolated and have no external volt-
age applied. These devices can be connected directly to the zone terminals without regard for polarity.
Choose a zone and connect the wires to the corresponding screw terminals for that zone. The following
figure shows how to connect a dry contact sensor:

2.8K/10K TEMPERATURE SENSORS
The Web600 is compatible with 2.8K/10K temperature sensors that match the curve data listed in the
UBCMFTJO"QQFOEJY'5IFNPOJUPSJOHUFNQFSBUVSFSBOHFPGUIF,UIFSNJTUPSJTUP'
to 57ºC) and the 10K thermistor is -87° to 168°F (-66° to 76°C). Temperature sensors can be connected
directly to the zone terminals without regard for polarity. Choose an input and connect the wires to
the corresponding screw terminals for that zone. 2.8K and 10K temperature sensors are available from
Sensaphone. See Appendix C for part numbers. The figure below shows how to connect a temperature
sensor:
