GST DC-9503E Manuals

30310469 Issue 1.04 Features  Isolation of short circuit, automatic restore when short circuit is cleared.  Maximum output current is 1A.  DIN-Rail mounted or Wall mounted.  Standard: EN 54-17:2005 Description In fire alarm system, such condition often occurs that partial short circuit of loop affects the whole system. DC-9503E Loop Isolator（hereinafter referred to as the isolator）can isolate the shorted circuit from the whole system to ensure normal operation of other devices and help locate the devices in fault. After the short circuit fault is cleared, those devices will be re-introduced into the system. The isolator is suitable for use in the loop of addressable fire alarm system. Connection & Cabling Terminals of the isolator are shown in Fig. 1. Fig.1 (I+, I-) IN & OUT: input signal loop, I+ is positive and I- is negative. O+, O-: output signal loop, O+ is positive and O- is negative. Recommended Wiring: 1.0mm2 or above twisted pair. Wires should not be laid out in the same conduit or raceway with Class 1 wires such as power cables, high and low voltage distribution cables and so on. Installation 1) Before installation, make sure the enclosure is in good condition and markings are complete. 2) The isolator can be mounted on a 35mm DIN-Rail as shown on Fig. 2. 3) The isolator can also be wall mounted by 4 mounting screws as shown in Fig. 3. Mounting space is 67mm. Fig. 2 Fig. 3 Application System connection is shown in Fig. 4. Note: Terminals of the isolator have polarities. 2831-CPR-F2019 GST-0017-01 18 548n/05 DC-9503E Loop Isolator 30310469 Issue 1.04 Fig. 4 Specification Operating Voltage Loop: 24VDC (16V - 28V) Power Limited Standby Current ≤ 0.15mA Action Current ≤ 1.5mA Capacity Maximum 70 devices Indicator Yellow, flashes in standby state, steady in fault.
