RSG RMS-3T-WP-KO SPDT Weatherproof Pull Station Key Operated

The RSG RMS-3T-WP-KO is a SPDT terminal-block-connection weatherproof pull station with the Key-Operated / Institutional (KO) option. Specifically, the KO suffix configures the key-operated / institutional. Furthermore, the SPDT contacts work with conventional and addressable initiating circuits.

First, the KO configuration replaces the pull lever with a keyed actuator. Then, only staff carrying the key can activate the station. As a result, casual users cannot trigger the alarm.

In addition, KO suits schools, correctional facilities, and behavioral-health units. However, key control depends entirely on site procedures. Therefore, confirm staffing and key-control practices before specifying.

RSG RMS-3T-WP-KO Option Detail

The KO option replaces the standard pull handle with a keyed actuator. Furthermore, the SPDT switch supports normally-open and normally-closed contacts. As a result, the station only activates when an authorized key is inserted and turned.
