GRI releases 4110 overhead door switch

The GRI 4110 is a "Vane" switch for use on storage units with overhead doors and latch-type locks.

When mounted on a roll-up door channel, the 4110 will not allow the alarm system to arm unless the bolt or latch is in a locked position.

Removal of or tampering with the bolt or latch removes the shunting effect and an alarm will be activated when the circuit is opened.
