Description

The 4098-9793 isolator base accepts Simplex TrueAlarm analog sensors and provides communications isolation to improve installation convenience and increase system integrity. An internal isolation relay allows a compatible c.i.e. to separate shorted communications wiring from functioning wiring to optimise the available sensors or other IDNet addressable devices. The isolator base’s status is communicated to the FIP, allowing it to assist in identifying the location of the shorted wiring. During installation, earth faults frequently occur. Finding these faults normally requires extensive wiring disconnection. With the 4098-9793 isolator base, earth faults on the IDNet communications lines can be quickly located to assist in their repair and to restore the system wiring
to normal.
