Waterflow/Tamper Module (One-gang standard mount)
Overview ⭐
✅ The GSA-WTM Waterflow/Tamper Module are part of Kidde’s Signature Series system ⭐
✅ They are intelligent analog addressable devices used to connect one or two Class B normally-open Alarm, Supervisory, or Monitor type dry contact Initiating Device Circuits (IDC). The function of the GSA-WTM is determined by the factory loaded “personality code”. The input modules gather analog information the initiating devices connected to them and convert it digital signals. The module’s on-board microprocessor analyzes the signal and decides whether or not to input an alarm. The microprocessor in each module provides four additional benefits - Self-diagnostics and History Log, Automatic Device Mapping, Stand-alone Operation and Fast, Stable Communicatio
Standard Features
• Monitor and waterflow/tamper applications Includes Alarm with delayed latching (retard) for waterflow applications, Supervisory, and Monitor.
• Non-volatile memory Permanently stores serial number, type of device, and job number. Automatically updates historic information including hours of operation, last maintenance date, number of alarms and troubles, and time and date of last alarm.
• Automatic device mapping Each module transmits wiring information to the loop controller regarding its location with respect to other devices on the circuit.
• Electronic addressing Permanently stores programmable address; there are no switches or dials to set. Addresses are downloaded a PC, or the SIGA-PRO Signature Program/Service Tool.
• Intelligent module c/w integral microprocessor All decisions are made at the module allowing lower communication speed while substantially improving control panel response time. Less sensitive to line noise and circuit wiring properties; twisted or shielded wire is not required.
• Ground fault detection by address Detects ground faults right down to the device level.
• Designed for high ambient temperature operation Install in ambient temperatures up to 120o F (49o C).
Application
GSA-WTM NORMALLY-OPEN ALARM - DELAYED LATCHING (Factory set Personality Code 2) - Assigned to one circuit. Configures circuit 1 for Class B normally-open Waterflow Alarm Switches. An ALARM signal is sent to the loop controller when the input contact is closed for approximately 16 seconds. The alarm condition is latched at the module.
GSA-WTM NORMALLY-OPEN ACTIVE - LATCHING (Factory set Personality Code 4) - Assigned to one circuit. Configures circuit 2 for Class B normally open dry contact Supervisory and Tamper Switches. An ACTIVE signal is sent to the loop controller when the input contact is closed. The active condition is latched at the module.
Installation
The GSA-WTM modules mount to North American 2-1/2 inch (64 mm) deep one-gang boxes and 1-1/2 inch (38 mm) deep 4 inch square boxes with one-gang covers and GSA-WTM mounting plates. The terminals are suited for #12 to #18 AWG (2.5 mm2 to 0.75 mm2 ) wire size. Kidde recommends that this module be installed according to latest recognized edition of national and local fire alarm codes.
Electronic Addressing - The loop controller electronically addresses each module, saving valuable time during system commissioning. Setting complicated switches or dials is not required. Each module has its own unique serial number stored in its on-board memory. The loop controller identifies each device on the loop and assigns a “soft” address to each serial number. If desired, the modules can be addressed using the SIGA-PRO Signature Program/Service Tool. Personality codes are assigned by the factory. No user configuration is required for these modules.
