Zone shunt units
Made in Britain
Description

This unit is designed to switch out (shunt) an active security system circuit thus allowing controlled access to a secure area.

This prevents false alarms, as access to the secure area is only possible once the door is unlocked and the circuit is shunted. The shunted zone can only be switched back in if the alarm circuit is clear. An output is available to provide remote indication whilst the unit is shunted.

The DA250U can be switched by either our DA228, DA225 or in certain circumstances our DA223 door lock keep. Alternatively the DA250LS has a built in keyswitch and a red LED which illuminates whilst the key operated switch is in the shunted position.
