GRI 4110-A Commercial Overhead Door Switch, Closed, 18" Armored Cable, Normally Open

• The GRI 4110A 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 4110 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
• The 4110A series is available with an 18 armored cable. It is a low profile, extruded aluminum switch mounted on an aluminum plate. Optional mounting kit available.
