The models RA400Z & RA400ZA remote annunciators are polarized devices designed for both conventional and intelligent applications. They have been designed using an active current regulator so that the maximum current required from the system is 10mA when the input voltage is within the specified voltage range.

Installation
The remote annunciator is intended to be mounted to a single gang electrical outlet box. The wiring must be in compliance with all codes. The device must be operated within its published specifications. Wire the remote annunciator according to the instructions supplied with the device being monitored. Polarity of the incoming wires must be observed and connected to the proper terminals “+” and “–”. (See Figure 1.) The tab on the back of the RA400Z and RA400ZA must be broken off for use with most System Sensor intelligent systems. (See Note 1 and Figure 4.) After tab is broken, the input voltage for the RA400Z and RA400ZA is limited to 18 volts minimum.
