The Annual Security System Inspection SOP

Purpose

An alarm system degrades quietly. A standby battery loses capacity a little each year and still charges to a normal voltage, a wireless sensor's cell runs down until its low-battery signal finally arrives on a Saturday night, a cellular communicator's signal slips after a carrier change, and a door contact gets painted over and stops reporting. None of that shows until the night it matters. This procedure inspects every part the system depends on once a year, in the same order, from the past year's signal history to a report the customer receives, so each problem is found by the shop on a weekday instead of by the customer at 2 a.m.

Scope

Covers an annual inspection of a residential or light commercial intrusion system under a service agreement: history review, battery, every zone, wireless signal and sensor batteries, keypads and siren, the communicator and the station's receipt of a test, findings, and the customer report.

Does not cover fire devices on a combination panel. Smoke, heat and CO detectors connected to the panel are tested only by a tech holding the license the jurisdiction requires, under NFPA 72 in the edition as adopted, through 'The Fire-Side Work and License Routing SOP'. Repairs beyond the inspection visit go to 'The Alarm Service Call SOP'.

Roles and responsibilities

Procedure

1. Pull and read the past year's signal history before the visit. The office requests 12 months of history from the station and attaches it to the ticket; the tech reads it the day before, per Reading Event Codes on a Signal History. Acceptance: a count written on the ticket for each of alarms, troubles, low-battery signals, AC losses and missed periodic tests. Wrong looks like a history with gaps where periodic tests should be; the stop rule is the communicator becomes the first thing inspected on site, ahead of the walk test. Hazard: none, desk work.

2. Put the account on test on arrival. Call the station, request a test window (the shop default is 3 hours for an inspection) and record the confirmation number and operator ID, per How to Put an Alarm Account on Test and Take It Off. Acceptance: confirmation number and window end on the ticket before any device is tripped. Wrong looks like a station that cannot find the account under the number in the file; the stop rule is no device is tripped until the account is located and on test. Hazard: none, a phone call.

3. Inspect the panel, transformer and enclosure. Open the panel and look before touching: transformer secured to its receptacle, no AC trouble on the keypad, wiring dressed and labeled, no corrosion on the battery posts, no swelling of the battery case, enclosure tamper working. Acceptance: tamper signal received at the station when the door opens, and each item marked on the record. Wrong looks like a swollen or leaking battery; the stop rule is that battery is disconnected and replaced this visit, not load tested. Hazard: a swollen lead-acid battery may vent; the tech wears eye protection and nitrile gloves, keeps it upright, and keeps tools from bridging the posts.

4. Load test the standby battery. Note the date written on the battery, then load test it by the method in How to Replace an Alarm Panel Battery and Load Test It, against the pass line on the shop's load-test card. Acceptance: voltage at the end of the test at or above the pass line, and a battery date within the shop's replacement age (the shop default is 4 years). Wrong looks like a battery that rests at a normal voltage and falls under load, which is a battery that has lost capacity but still charges; the stop rule is replace it this visit if one is on the truck, otherwise quote it and write it as a finding. Hazard: if the test removes AC, the tech restores it at the end of the step and confirms the AC trouble clears on the keypad; leads are fitted red then black with the transformer unplugged.

5. Walk test every hardwired zone with the station. Trip each zone and have the operator read back zone number and event, per How to Walk Test Every Zone with the Central Station. Acceptance: every zone received under its own number with the description the account holds. Wrong looks like no signal, the wrong zone, or a contact that only reports with the door pulled hard; the stop rule is the zone is repaired this visit if it is a contact realignment or a loose terminal, and quoted if it needs new wire. Hazard: motion detectors and contacts above 6 ft are reached from a stepladder set on level floor, never from furniture.

6. Check every wireless sensor's signal and battery. Read each wireless zone's signal on the panel's diagnostics with the sensor in place, and read its battery status. Replace any cell the panel reports low or the maker's schedule calls due, with the cell type the maker specifies. Acceptance: each signal at or above the maker's stated minimum, no low-battery status, and a trip received at the station. Wrong looks like a signal that has fallen since install, often from a new appliance, mirror or metal shelving; the stop rule is relocate the sensor or add the maker's repeater, and record which. Hazard: lithium coin and cylinder cells are kept out of pockets with keys or coins, and spent ones are taped across the terminals before they go in the battery bucket.

7. Test keypads and the siren. Press each keypad's panic, if programmed, with the station watching, and confirm every keypad shows the same status. Sound the siren for a few seconds (see related: How to Install an Alarm Siren and Check Its Output). Acceptance: panic received, siren audible through a closed bedroom door. Wrong looks like a keypad with a dead display or a siren that crackles; the stop rule is quote the part. Hazard: ear protection for the tech and a warning to the household before the siren sounds.

8. Confirm the communicator and the periodic test. Read the communicator's signal strength on its diagnostics (see related: Cellular Backup and Alarm Communicators), send a manual test, and confirm with the operator that it arrived and that the account's periodic test interval matches what the panel is programmed to send. Acceptance: signal at or above the maker's stated minimum, manual test received, the station's interval matching the panel's. Wrong looks like a strength reading near the floor or a mismatched interval; the stop rule is relocate the antenna if the maker allows it, otherwise quote, and correct the interval at the panel or the station before leaving. Hazard: none beyond the open panel in step 3.

9. Fix or quote every finding. Items fixed on the visit are written as fixed with the reading after; items not fixed are priced as a quote with a priority: now, at the next visit, or monitor. Acceptance: every failed line on the record has a disposition. Wrong looks like a finding with no disposition; the stop rule is the record is not closed. Hazard: none, paperwork.

10. Take the account off test and send the report. Close the panel, send one final test, have the operator confirm receipt, take the account off test, record the operator ID. The office sends the record and any quote to the customer within 2 business days. Acceptance: confirmed final signal and a sent report. Wrong looks like an account still on test after the truck leaves; the stop rule is the tech stays until the station confirms it is live. Hazard: none, a phone call.

The record this produces

The filled inspection record below, the history counts from step 1, both confirmation numbers, the quote, and the date the report was sent. The office reads it to book repairs, next year's inspector reads it to see what was deferred, and it is the shop's proof that a deferred item was disclosed.

A worked pass

A 10-zone panel, 7 hardwired and 3 wireless, installed March 2022, inspected October 2026.

Final signal rcvd 10:40, acct off test

Step 1 found 2 low-battery signals from zone 9, so the tech carried the maker's cell for that sensor. Step 4 failed: the battery was 4 years 7 months old against the shop's 4-year default and fell below the card's pass line under load, so the stop rule replaced it on the visit and the new battery was tested the same way. Step 6 replaced zone 9's cell, which explains both low-battery signals in the history. The one AC loss in the history lined up with a utility outage date the customer remembered, so it was recorded as explained rather than a finding.
