When an unexpected spark or sudden haze threatens your home or business, HEPâs rapid-response team in Reliance is already primed to act. Our licensed electricians install, test, and maintain smoke detectors that communicate instantly with our 24/7 dispatch center, triggering a coordinated response that can cut power, isolate the fault, and alert the fire department in seconds. The result is a seamless safety net that turns a silent potential hazard into a clearly managed eventâoften before you even realize something is wrong.
From comprehensive wiring inspections to same-day replacements, every service call is driven by the promise of speed, transparency, and lasting protection. Choose HEP and gain not only expertly installed smoke detectors, but also the confidence that comes from knowing a dedicated crew is always watching over the circuits that watch over you.
FAQs
How do Reliance rapid-response electrical smoke detectors differ from conventional models?
Reliance detectors combine photo-electric sensing with a micro-controller that analyses particle density 10 times per second. When smoke is detected, the built-in relay activates in under 2 seconds, triggering alarms, strobes or building management notifications. Conventional detectors typically sample every 8â10 seconds and rely on an external control panel to decide if an alarm should sound, which can add several seconds to the response time.
What electrical requirements and wiring configurations are needed for installation?
Each detector operates on 24 V DC supplied from a listed fire-alarm power source. Two wiring options are supported: (1) Class B (Style B) 2-wire for power and signalling, or (2) Class A (Style D) 4-wire for power, signalling and remote annunciation. The units draw 60 ÂľA in standby and 20 mA in alarm. For retrofit projects, existing 18/2 or 18/4 fire cable is usually sufficient, but we recommend confirming conductor integrity and voltage drop over the run length.
How often should the detectors be tested and what maintenance is required?
⢠Test monthly with the built-in magnet or remote test station to verify electronics and relay function. ⢠Perform a functional smoke test twice a year using canned smoke or a smoke-generator cup. ⢠Vacuum the sensing chamber annually to remove dust; sensors are field-replaceable if contamination persists. ⢠Replace the detector head every 10 years to comply with NFPA 72 and manufacturer guidance. ⢠Keep a log of all tests and maintenance to maintain code compliance and warranty coverage.
Can Reliance smoke detectors integrate with my existing fire alarm or BMS platform?
Yes. The detectors provide Form C dry contacts (NO/NC) plus optional Model IF-485 modules that convert status data to Modbus RTU or BACnet MS/TP. This allows seamless connection to most addressable fire panels, intelligent relays or building management systems for centralised monitoring, event logging and remote reset.
What safety standards and certifications do the detectors meet?
All Reliance rapid-response detectors are UL 268-8 listed for smoke detection and UL 864 recognized when used in a listed system. They also carry CE marking for the Low Voltage Directive and EN 54-7 compliance for the EU. The housings are made from UL 94 V-0 flame-retardant plastic and meet RoHS and REACH directives for hazardous substances.
What should I do if a detector goes into alarm?
1. Evacuate occupants immediately following your buildingâs emergency plan. 2. Identify the alarmed detector via the panel or local LED: a steady red LED indicates smoke. 3. If safe, investigate the area for signs of fire. If fire is confirmed, call emergency services and use suppression equipment. 4. Once the area is clear and fire services have given the all-clear, press the system reset button or momentarily remove power to the detector to clear the alarm. 5. Document the event and schedule a maintenance check to ensure the unit remains in optimal condition.
