{"product_id":"edwards-siga-wtm","title":"EDWARDS SIGA-WTM Waterflow Tamper Module","description":"\u003cp\u003eThe \u003cstrong\u003eEdwards SIGA-WTM\u003c\/strong\u003e is an intelligent addressable waterflow and tamper interface module for Edwards Signature Series loops. Specifically, it monitors one waterflow switch and one supervisory or tamper switch on a sprinkler system. As a result, both signals arrive at the panel as individually identified points.\u003c\/p\u003e\n\u003cp\u003eIn addition, the SIGA-WTM uses two device addresses on the Signature loop. Therefore, the panel can distinguish a waterflow alarm from a tamper or supervisory condition without ambiguity.\u003c\/p\u003e\n\u003ch3\u003eHow the Edwards SIGA-WTM Works\u003c\/h3\u003e\n\u003cp\u003eFirst, the waterflow input includes a built-in retard timer of approximately 16 seconds. As a result, momentary water pressure surges do not generate false alarms. Then, after the retard expires, the module reports a latching waterflow alarm.\u003c\/p\u003e\n\u003cp\u003eFurthermore, the second input handles tamper or supervisory switches. Specifically, it latches on any active condition and clears only after the panel issues a reset.\u003c\/p\u003e\n\u003cp\u003eIn addition, the module uses electronic addressing. Therefore, no dip switches or rotary dials are required during installation.\u003c\/p\u003e\n\u003ch3\u003eCritical Compatibility Note\u003c\/h3\u003e\n\u003cp\u003eThe SIGA-WTM does NOT support 2-wire smoke detectors. Therefore, do not connect conventional 2-wire smoke detectors to either input. Instead, use a SIGA-CC1 or SIGA-MM1 configured for the appropriate input type.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFunction: Intelligent waterflow + tamper\/supervisory monitor module\u003c\/li\u003e\n\u003cli\u003eInputs: 2 × Class B (waterflow ~16 s retard; tamper\/supervisory latching)\u003c\/li\u003e\n\u003cli\u003eAddresses used: 2 (one per input)\u003c\/li\u003e\n\u003cli\u003ePower: 15.2 to 19.95 VDC from the Signature SLC\u003c\/li\u003e\n\u003cli\u003eCurrent: 396 µA standby; 680 µA active\u003c\/li\u003e\n\u003cli\u003eStatus LEDs: Green (polled) and red (active\/alarm)\u003c\/li\u003e\n\u003cli\u003eIDC loop limits: 50 Ω total, 0.1 µF maximum per circuit\u003c\/li\u003e\n\u003cli\u003eMounting: Standard 1-gang electrical box\u003c\/li\u003e\n\u003cli\u003eDoes not support: 2-wire smoke detectors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCompatible Edwards Panels\u003c\/h3\u003e\n\u003cp\u003eThe SIGA-WTM works with Edwards Signature-loop control panels.
