Operation  操作

With the key in the Main position, the green LED will be lit and the release circuit will be connected to the main bank of the extinguishing agent. Turning the key to the Reserve position turns off the green
将钥匙置于 Main 位置时，绿色 LED 将亮起，释放电路将连接到灭火剂的主组。将琴键转到 Reserve 位置会关闭绿色
LED and lights the yellow LED while disconnecting the release circuit from the main bank of the extinguishing agent and connecting it to the reserve bank.
LED 并点亮黄色 LED，同时断开灭火剂主组的释放电路并将其连接到储备组。

Engineering Specification
工程规格

The Main/Reserve Switch shall be capable of switching the release output of a release panel to either a primary (main) or secondary (reserve) source of extinguishing agent. The unit shall consist of a DPDT key operated switch rated for 1 Amp at 40 VDC mounted to a stainless steel faceplate with a green and yellow LED. The green LED shall be labeled Main and shall only light when the key is in the main position. The yellow LED shall be labeled Reserve and shall only light when the switch is in the reserve position. The Key shall be removable in either position. The unit shall be designed to mount on a standard single gang enclosure. The Main / Reserve Switch shall be a Potter model MRS or equivalent.
主/备用开关应能够将释放面板的释放输出切换到灭火剂的主（主）或辅助（备用）灭火剂源。该装置由一个 DPDT 按键作开关组成，在 40 VDC 下额定电流为 1 安培，安装在带有绿色和黄色 LED 的不锈钢面板上。绿色 LED 应标记为 Main，并且仅在按键位于 main 位置时亮起。黄色 LED 应标记为 Reserve，并且仅在开关处于 Reserve 位置时亮起。钥匙可在任一位置拆卸。该装置设计为安装在标准的单组外壳上。主/备用开关应为 Potter 型号 MRS 或同等型号。
