Power supply 24v 2A + 0.8 APM702C
The PM702C is a full-featured EN54-4-approved power supply, ideal for use in fire system applications. It features intelligent battery charging, monitoring and signaling. The 27.6 VDC regulated output will generate up to 2 A in the charge and provide up to 0.8 A to charge the backup batteries. The charging output features full electronic short-circuit protection in both network battery operation and standby mode. Maximum battery life is ensured through continuous active battery monitoring and 3 different charge levels: volume (fast charging), absorption and temperature-compensated flotation. Deep discharge protection prevents premature battery failure when operating from standby mode for extended periods of time. Inside the unit, a diagnostic LED with various flashing patterns ensures accurate diagnosis when the unit fails.
How to install 24v 2A + 0.8 APM702C Power Supply
A PM702C power supply is supplied in a stand-alone wall mount box that can also accommodate 17 Ah batteries (not included). The battery charging circuit is energized only when a battery is properly connected and the battery voltage is greater than 14 V. A green LED and a red LED that is visible when the box is closed indicates network presence and failures. A red diagnostic LED inside the unit distinguishes between several faults by various flicker patterns. A potential-free contact is used to report faults due to output failures, battery failures, charger failures, or internal failures. A second potential-free contact signals network loss. The unit starts automatically withbattery life, i.e. it connects the battery and the unit works. The power grid does not need to be present and is very useful for commissioning in newly built installations.
