Commercial Overhead Door Switch
Special Order
The GRI 4110/4482 Series is basically a vane switch for use on storage units with overhead doors and latch type locks. Intended to be mounted on a roll up type door channel, the GRI Vane Switches will not allow the alarm system to arm unless the bolt or latch, which serves as a shunt between the reed switch and magnet, is in a locked position. Removal or tampering of the bolt or latch removes the shunting effect and an alarm will be activated when the circuit is opened.
Dimensions: 2.25 x 1.75 x .55
