The NXFOB is a dual button fob that can be used in conjunction with the ALERTEX Wireless Alert system. The keyfob acts as a portable call point and activates the ALERTEX system when both buttons are pressed and held for 4 seconds; this helps to avoid false activation. Users must be within 100m of standard ALERTEX alerts. The LED light on the fob shows the status of the device when transmitting. A lanyard with a breakaway clip is supplied with the unit so that it may be worn around the neck and accessed easily in case of a lockdown situation. The keyfob counts as one of up to 64 ALERTEX units that can be used per site.
