The RSG RMS-3T-KL is an SPDT terminal-block-connection manual pull station with a Key-Lock (KL) reset. Furthermore, it suits commercial fire alarm circuits where only authorized staff should clear an activation.
First, pulling the lever activates the alarm. Then, the cover stays latched until a key is turned. As a result, casual or accidental reset cannot clear the device.
In addition, KL reset is common in retail, schools, and assembly venues. However, the key catalog (Cat 30, 45, 60, etc.) varies by site standards. Therefore, confirm the keying standard before placing the order.
RSG RMS-3T-KL Option Detail
The KL option adds a key-lock reset mechanism to the standard lever. Furthermore, the SPDT switch supports normally-open and normally-closed wiring. As a result, the station combines familiar pull activation with restricted reset.
