500 Series Intelligent Modules The System Sensor intelligent module products are designed to meet a wide range of applications. Features • SEMS screws for easing wiring • Panel controlled status LED (except M501M) • Analog communications • Rotary address switches (except M500X) • Low standby current • Mounts in standard 4˝ junction box Monitor and control modules can be used to supervise and activate sounders, strobes, door closers, pull stations, waterflow switches, conventional smoke detectors, and more. Each module is rigorously designed and tested for electromagnetic compatibility and environmental reliability, in many cases exceeding industry standards. Modules are addressed with easy-to-use rotary code switches. Full size modules mount in standard 4 in × 4 in × 21⁄8 in junction box. Wiring terminals are easily accessible for troubleshooting. M500M Monitor Module, M501M Mini Monitor Module, and M500DM Dual Input Monitor Module System Sensor monitor modules provide an interface to contact devices, such as security contacts, waterflow switches, or pull stations. M501M and M500DM are capable of Class B supervised wiring to the monitored device. M500M is capable of Class A supervision. Conventional 4-wire smoke detectors can be monitored through their alarm and trouble contacts, wired as an initiating loop to the module. In addition to transmitting the supervised state of the monitored device (normal, open, or short), the full analog supervision measurement is sent back to the panel. This allows detection of impedance changes in the supervised loop to the monitored device. The M500DM module is capable of monitoring two separate Class B circuits simultaneously, making it ideal for waterflow tamper switch and flow switch monitoring. The compact size of the M501M module allows it to fit inside devices or junction boxes behind devices. Agency Listings M500X Isolator Module The M500X Isolator Module is an automatic switch that opens when the line voltage drops below four volts. Isolator modules should be spaced between groups of sensors or modules in a loop to protect the rest of the loop. If a short occurs between any two isolators, then both isolators immediately switch to an open circuit state and isolate the devices between them. The remaining units on the loop continue to fully operate. The number of devices that can be installed between isolator modules varies depending on the device type. Please see your module's manual for more information. continued M502M Zone Interface Module The M502M Zone Interface Module allows intelligent panels to interface and monitor 2-wire conventional smoke detectors. All 2-wire detectors being monitored must be UL or ULC compatible with the module. The M502M module is addressed through the communication line of an intelligent system. It transmits the status of one zone of 2-wire detectors to the fire alarm control panel. Status conditions are reported as normal, open, or alarm. The interface module supervises the zone of detectors and the connection of the external power supply. M500S Control Module The M500S Control Module provides supervised monitoring of wiring to load devices that require an external power supply to operate, such as horns, strobes, or bells. It is capable of Class A and Class B supervision. Upon command from the control panel, the M500S module will disconnect the supervision and connect the external power supply across the load device. The disconnection of the supervision provides a verification to the panel that the control relay actually turned on. The external power supply is always relay isolated from the communication loop, so that a trouble condition on the power supply will never interfere with the rest of the system. Full analog measurement of the supervised wiring is transmitted back to the panel and can be used to detect impedance changes or other special test functions. M500R Relay Module The M500R Relay Module contains two isolated sets of Form C contacts, which operate as a DPDT switch. The module allows the control panel to switch these contacts on command. No supervision is provided for the notification appliance circuit. M500FP Firefighter Phone Module The M500FP module is intended to monitor and control a loop of firefighter phones. It has the ability to differentiate between normal, off-hook, and trouble conditions. When taken off-hook, a phone will immediately receive a ringing tone, and the panel will receive an offhook indication. The panel can then connect that off-hook phone to the main riser for the system. 500 Series Intelligent Module Specifications General Specifications Operating Voltage Communication Line Loop Impedance Temperature Range Relative Humidity Shipping Weight Dimensions Specifications, M502M Standby Current External Power Supply End-of-Line Resistance External Supply Standby Current External Supply Alarm Current Specifications, M500R Standby Current LED Current Relay Contact Ratings 15 to 32 VDC 40 Ω max. 32°F to 120°F (0° to 49°C) 10% to 93% noncondensing M501M: 1.2 oz (37 g) Others: 6.3 oz (196 g) M501M: 2.7 in W × 1.7 in H × 0.5 in D Others: 4.275 in W x 4.675 in H x 1.4 in D 300 µA max @ 24 VDC (one communication every 5 sec. with LED enabled) 18 to 28 VDC (100 mV ripple max.) 3.9 kΩ (included) 11.5 mA @ 24 VDC (nominal) 80 mA @ 24 VDC (nominal) 300 µA max @ 24 VDC (one communication every 5 sec. with LED enabled) 5.5 mA (with LED latched on) 2.0 A @ 25 VAC (PF=.35), non-coded 3.0 A @ 30 VDC resistive, non-coded 2.0 A @ 30 VDC resistive, coded 0.46 A @ 30 VDC (L/R=20ms), non-coded 0.7 A @ 70.7 VAC (PF=.35), non-coded 0.9 A @ 125 VDC resistive, non-coded 0.5 A @ 125 VAC (PF=.75), non-coded 0.3 A @ 125 VAC (PF=.35), non-coded Specifications, M500X Standby Current Isolation Impedance Fault Detection Delay Fault Detection Threshold Line Restoration Threshold Specifications, M500DM Standby Current 450 µA max. 2.25 kΩ to 2.9 kΩ 250 ms min. 4 Volts 7 Volts 750 µA max. @ 24 VDC (one communication every 5 sec. with 47k EOL) Alarm Current 970 µA max.
