Recommended Battery: DSC Model BD7-12 BATTERY CHARGE CURRENT SELECTOR JUMPER ON A-B = 400mA JUMPER ON C-B = 700mA NO JUMPER = FOR FUTURE USE Primary 120VAC 60Hz, 0.3A TRANSFORMER DSC Model PTC1640UG OUTPUT RATING: 11.5VDC - 12.6VDC, 1.5A Note: Devices that require power from the PS4085 shall be UL Listed for the intended application and operation over the range 11.5-12.6VDC Terminal Descriptions AC - Supervised input. Connect the secondary of the transformer to these terminals. Connect the primary of the transformer to a dedicated electrical circuit (commercial fire installations) or to an unswitched AC source (other applications). +12V/COM - Special applications output circuit, power limited. Connect to devices that require power. Connect the positive lead of powered devices to the +12V terminal and the negative lead to the COM terminal. ACT - This open collector output activates when an AC Trouble is detected: Rated 50mA. LBT - This open collector output activates when a Battery Trouble condition is detected: Rated 50mA. TEST - This open collector output activates when the charging circuit is in a trouble condition: Rated 50mA. These outputs may be used to activate an indicating device, such as an LED, or a relay to activate devices requiring more current. The terminals may also be connected to a control panel zone input to generate an alarm and to have the system report trouble conditions. To report AC failure and low battery conditions with individual reporting codes, connect the ACT and LBT to individual alarm zones. The ACT and LBT terminals may also be connected to a single alarm zone. When so connected, both trouble conditions are reported with a single reporting code. +BAT/-BAT - Used to connect the standby battery, non-power limited. Use single or dual lead battery wire assembly. Battery Charge Current Select the battery charge current using jumper “CON1”. To avoid damage to the battery, do not select a battery charge rate greater than 0.1 times the battery AHr rating. Jumper Setting Charge Current Battery Size A-B 400mA 4Ah B-C 700mA 7Ah, 14Ah None Future Use N/A Note: For UL Listed installations use only 700mA setting. Applying Power After all wiring is complete, connect the battery leads to the battery, then connect the AC trans- former. For information on the power requirements of specific devices, refer to the instructions sup- plied with the device. IMPORTANT! Do not connect power until all wiring is complete. Mounting the Cabinet When mounting the cabinet, select a dry location within 1m/3.3ft of the control panel. To mount the cabinet: 1. Press 4 white circuit board stand-offs into the raised mounting holes at the back of the cabinet. 2. Hold the cabinet in position and pull all wiring through the holes in the back. 3. Using the provided mounting screws and appropriate wall anchors, mount the cabinet securely to the wall. 4. Press the PS4085 module onto the plastic stand-offs. Enclosures The PS4085 can be installed in the metal enclosure described below. Tamper protection switches can be installed on all enclosures, including door opening protection and/or removal from the mounting pos- ition. Doors can be secured using screws or keylock. Internal and/or external wiring for this module shall be routed, supported, clamped or secured in a manner that reduces the likelihood of the following: • excessive strain on wire and on terminal connections. • loosening of terminal connections. • damage of conductor insulation.
